Industrial Applications

 

Q: Will the recycled solvent meet or exceed virgin solvent purchased?

Yes, in most cases with every cycle, as long as the system is operated correctly in accordance with the provided operator’s manual. The quality of the recycled solvent will meet or exceed virgin solvents and will not contain contaminant carry-over.

 

Q: Is the system safe?

Yes. CBG recycling systems are UL2208 listed with additional built-in safety features. Automatic shutdown sensors and pressure-relief valves are standard on the TechnoClean® systems. For those customers who want to recycle, but need to do so in a recycler in a hazardous setting, CBG offers Class 1/Division 1 for these specific needs.

 

Q: How much operator time is required to run the recycling system?

Approximately 15 minutes per day. This accounts for loading the solvent/waste into the recycler, closing the lid and hitting the start button. No further interface is required—the system operation is automatic and will monitor itself, even during the final shut down phase.

 

Q: Why do I need to use tank liners?

Tank liners are recommended for all recycling projects that contain a solid contaminant(s). The liners make it easier to dispose of the final solid waste.

 

Q: Can CBG provide system or electrical drawings/schematics?

Yes. Simply contact us and we will provide them to you.

 

Q: What permitting is required to operate CBG recycling systems?

Most states follow the Resource Conservation and Recovery Act (RCRA) regulations found under 40 CFR 261.4(a)(8), which identifies the process as being exempt. Please also check with your local regulatory agency.

 

Q: What are the routine maintenance recommendations for the system?

CBG recommends changing the thermal heating oil every 1,000 hours along with replacing the tank lid seal with each oil change. CBG offers preventive maintenance services and DIY kits to support these recommendations.

 

Q: What warranties do the systems have?

All industrial F Series recyclers come with a 12-month parts and labor warranty. All industrial S Series recyclers come with a 12-month parts warranty.

 

Q: What type of financing options does CBG offer?

Solvent/Acetone/Formalin Recycling Questions

 

Q: How much operator time is required for using a CBG Biotech recycler?

Approximately 15 minutes on average to load, fill, start the cycle and unload the recycled product. This unit is totally automated and self-contained. CBG recyclers are designed for easy operation and don’t require highly trained technical staff to operate.

Q: How long does each cycle take?

The actual length of each cycle depends upon the type of material(s) being recycled, the volume of the material, and the type of recycler being used. However, the following is a good generalization:

Product

Bench Top and Standard, Cart-Mounted Models

Xylene and Xylene Substitutes

1 hour per gallon

Alcohols

1.25 to 1.5 hours per gallon

Formalin

2 hours per gallon

Acetone

1 to 1.5 hours per gallon

 

Q: How long does it take to clean the equipment?

The unit is self-cleaning when operated correctly in accordance with the provided operator’s manual, and no cleaning is necessary. Wastes dispense automatically to collection containers for easy disposal.

 

Q: Can the equipment run overnight?

Yes. CBG recyclers are approved to UL standards for distillation equipment and are safe to run unattended. If the unit malfunctions, it is designed to sound an alarm and shut down safely. Many labs start a cycle before employees leave for the day, that way they can arrive to fresh product in the morning. You will also gain increased throughput with this feature.

 

Quality Questions

 

Q: What is the solvent quality?

Purity: 99%

Recovery: 80% to 95% (depending upon solvent)

Q: How do we prove that the solvent is purified? Does the solvent need testing after distillation?

Neither the College of American Pathologists (CAP) nor the Joint Commission (JCAHO) requires any special testing of the recycled solvent(s) before use; you test and use the products, in the same manner, you would use vendor solvents. There is a hydrometer provided with alcohol recyclers to allow the user to check the concentration of the recycled alcohol. For xylene and xylene substitutes, there is a simple test in the operator’s manual to verify the purity. Contact CBG Technical Support for information on formalin testing.

Q: Does the quality and/or purity of a solvent change over time, as the solvent is repeatedly recycled?

No. In fact, the recycled solvent is usually a higher quality when compared to the vendors’ originally supplied starting grade, due to the purification that results from the fractional distillation process. The solvents themselves are extremely stable and generally do not show measurable decomposition, even after many years of storage at elevated temperatures.

Q: Why is fractional distillation, as compared to simple distillation, so important to my solvent recycling?

The simple answer is that you need fractional distillation to obtain the high-purity solvents you need for your work. Fractional distillation can separate two or more volatile liquids from one another while yielding good purities. Simple distillation, by contrast, collects all of the liquids together without very much, if any, separation of the individual solvents.

Q: What happens if the mixture has other solvents apart from xylene, acetone and water?

Collection is the most important part of successful recycling. If different solvents are in use, each solvent must be collected separately and recycled in the appropriate program. Contaminants consistent with the use of that solvent (i.e., carryover of eosin into the alcohol rinse stations on the histology staining line) are removed in distillation. However, if your lab uses both xylene and a xylene substitute, they should be collected separately and recycled separately.

Q: What if there are suspended solids?

Fine mesh strainers that fit in the fill carboys are provided to allow larger particulate matter to be removed during the fill process. Units with fill pumps have an additional strainer as part of the pump assembly. Particulate matter, such as cellular debris, is not volatile and will be collected as part of the waste at the end of the distillation cycle.

Q: Can absolute alcohol be recycled?

Yes. If collected separately, absolute alcohol will yield a recycled product of 98 to 99% in concentration. This recycled product can be used in processing stations for cleaning and in other applications, depending on your laboratory operations. Due to the alcohol/water azeotrope, a 100% concentration cannot be achieved as a recycled product.

 

Safety Questions

 

Q: Are there any fire risks?

There is no vapor escape. The unit is approved to UL standards for distillation units and was developed in accordance with the rules and regulations in the Uniform Fire Code (UFC) and the National Fire Protection Association (NFPA).

Q: Are there any leak risks?

The interior components are a closed system. The main source of leaks is through improper use of spigots (i.e., a spigot left open on a recovery carboy). Should a leak occur, the recycler has a built-in containment compartment, so a spill would be trapped in the unit.

Q: Does a CBG Biotech solvent recycler need any water hook-ups or special ventilation system?

No. All solvent recyclers are air-cooled using multiple, internal fans. This feature, coupled with both the “no-pour gravity-fill” and “vapor-recovery” systems, ensures that no vapors or odors will be released into your working area.

 

Cost Questions

 

Q: Does your company have a cost-benefit worksheet to help to determine which particular unit will best suit our needs?

Yes. Your sales representative will supply a form for you to enter the volumes and costs of the reagents you use, including the costs for disposal of those solvents. You can start the process here to determine the economic benefits in your laboratory.

Q: What if I don’t have any capital funds but would like to start recycling? How is that possible?

CBG has a variety of programs that can work toward your individual needs. If you need cost savings, we can show you how to address this objective. For example, we offer short-term rental programs that will bridge the gap between the end of your evaluation period and the time when you're purchasing or leasing funds become available. The actual rental payments can come from a noncapital fund budget, and it will cost you less than you’re currently paying to buy new solvents and dispose of old solvents.

In some instances, a portion of your rental payments may be applied to your recycler purchase price. We offer operating leases that can be handled through a noncapital fund budget. The lack of capital funds should not be a hindrance if your facility wants to pursue its recycling journey.

Q: What are the benefits of recycling?

There are numerous benefits to recycling. You simply use, recycle and reuse your solvents at the point of generation; they never leave the area. Your facility saves a lot of money through not having to buy new solvents and not having to pay someone to remove and dispose of your old solvents.

You will also save on the cost of storage space and storage lockers. Savings can also be achieved because you will no longer need to transport hazardous and flammable liquids in hospital corridors and you won’t need to store these solvents in a central location. Finally, recycling is becoming required as part of various federal, state and local mandates on waste minimization and sustainability. Waste minimization makes good sense as a way to avoid compliance problems, and is also good for the environment. Recycling is a way of “doing good while saving money” that also saves you time and space.

 

Service Questions

 

Q: What service programs are offered?

CBG offers a Total Replacement Policy (TRP). If the unit malfunctions and the problem cannot be resolved by our technical support staff over the phone, a replacement unit will be provided. CBG also offers standard and premium onsite preventive maintenance (PM) programs. Our Upgrade program provides trade-in credit for older models and provides for changes in volume and space.

Q: How many years have you been selling this equipment?

CBG has been manufacturing distillation devices since 1995. Although distillation equipment has been used in laboratories for many years, we have become the market leader by researching the needs of laboratories and developing recyclers that meet those needs by dramatically improving their safety and ease of use.



Essential Oil Applications

SRS Series | EPD=R Systems

SRS Series Equipment

Q. What is the solvent throughput amount and what can the solvent recovery tank hold?  

The solvent is distilled from CBG’s SRS Series equipment at different rates of recovery, depending on your operating temperature.  CBG’s SRS I unit runs at a default operation temperature of 130°C and has an approximate solvent recovery rate of > 2 gallons per hour.  Comparatively, SRS II unit runs at a default temperature of 70°C and recovers roughly 1.5 gallons per hour.  In general, the rates of distillation are faster at the beginning of the process as compared to the end of the process when there is less solvent present in CBG’s distillation apparatus/unit.   

CBG’s SRS simple distillation tank is either 8 or 15 gallons and can connect to a larger tank or drain for solvent recovery.   

Q. What is the amount of solvent recovered per run?

The amount of solvent recovered per run can vary depending on the quantity of recoverable oil/extract or solids which may be present in the solvent when introduced into CBG’s distillation unit.  With that said, in general, solvent recovery volumes are 90-97%, depending on the amount of solids and/or extract/oil contained in the solvent when introduced into CBG’s distillation unit.

Q. What is the solvent output?

The solvent output from CBG’s unit is anywhere from 1.5 – 2.0 gallons per hour.   If an operator of CBG’s equipment can run on higher operating temperatures, meaning above 130°C (SRS1), above 70°C (SRS2), the rates of distillation and recovery of solvent will be greater – upwards of 3 gallons per hour recovery.  

It should be noted that CBG’s equipment is versatile in that it can be used for multiple solvent streams.  Therefore, if you, as our customer, are using pure ethanol, isopropyl alcohol and other carrier solvents in your operations, you have the ability and flexibility with CBG’s equipment to recover all of these solvents (by running separate processing runs with these individual solvents).   This improves yield, reduce your cost and aids the environment by recovering all organic solvents used in your operations.  

Q. How much solvent is left in my product after distillation?  

CBG’s simple distillation apparatus is geared for industrial and higher throughput applications.   Our equipment is designed for demanding applications.   Our equipment maintains a rugged industrial design, which will stand up over time to your demanding and growing requirements.   

Assuming that oil/extract is introduced into our distillation unit together with ethanol, the amount of remaining ethanol in the product depends on your desired end product and its application.  We have customers that drive and utilize our equipment to “dryness.”  Other customers will retain residual ethanol in the oil/extract at the end of the process (removing in excess of 95% of the ethanol from the product) and then perform post processing steps which are appropriate for the oil/extract and its final end application.

 Q. What are the electrical requirements?

In the case of CBG’s SRS 1 unit, the electrical requirements are 220-240 V/1 PH/60Hz.  There is one 30 amp power feed needed for the SRS 1 Series. 

Comparatively, for the SRS II Series, this unit runs on 220-240 V/1 PH/60Hz.  The SRS II Series equipment requires one 30 amp power feed for the recycler and one 30 amp power feed for the chiller.  

Q. What are your run times?  

The capacity of our distillation equipment is roughly 8 gallons (up to 15 gallons).   Therefore, with the 8 Gallon SRS 1 Series, run time will be approximately 4 hours, as the equipment will drive off approximately 2 gallons per hour of solvent through the distillation process.  

By comparison, the 8 Gallon SRS 2 Series will drive off approximately 1.5 gallons per hour arriving at a cycle time for 8 gallons of solvent of approximately 5.5 hours.  

In each case, our equipment and the temperature set points associated with our equipment can be adjusted.  Thus, if you or your customer wants to run at a slightly higher setting, then the evaporation rates will increase and the cycle times will decrease.   

Q. Can you use existing processing with your equipment?   

In general terms with our SRS Series equipment, the answer is yes.   In fact, CBG’s SRS Series equipment, while being ideally suited for distillation applications, also has the ability to support our customers who are working with essential oils through a Decarb process.  CBG’s customers physically introduce plant material into our distillation tank and are able to utilize the distillation tank as a Decarb mechanism for your valuable plant products.   

 It should be noted that CBG’s equipment has the ability to Decarb both flower and stem product, which may be used for the extraction of valuable essential oils.  

On this basis, CBG’s equipment is ideally suited to support CO2 extraction.  CBG’s equipment is currently used by customers who are performing CO2 extraction.  Our equipment is often used to Decarb biomass product prior to introduction into a CO2 extractor.   Subsequently, post CO2 extraction, our equipment is used to drive off ethanol, which is used to purify and separate fats, waxes and lipids from the CO2 extraction.

 In conjunction, post extraction, CBG’s recycling equipment can be used to Decarb your valuable essential oils after solvent removal.  Our equipment can and will effectively Decarb your essential oils post extraction, while your solvent is being removed and recovered.  Many of our customers use CBG’s equipment in this fashion to enable fast throughput.  Through utilization of CBG’s equipment in this part of your process, you effectively take two process steps (Decarb and distillation/solvent removal) and consolidate them into one step, thereby simplifying your production and saving time.

Q. Do you offer scalability?   

Currently, CBG offers the SRS I and the SRS II Series in 8 gallon and 15 gallon configurations.   CBG has the ability to increase scale depending on your demands up to a 30 gallon unit.  It should be noted that processing times will increase with the volume of the equipment. That said, as CBG’s equipment is automated via programming and our controller, the equipment can be engaged and left to run until end of cycle.  This is different from other methods of distillation, which often require constant monitoring, frequent attention and involve glass and glassware, which is breakable.  Our equipment is able to perform this automated feature through a series of level sensors, heat sensors and controller which monitor the status of the distillation.   

 Q. Are your systems UL certified?

Yes, CBG’s equipment is UL2208 and UL610101 certified.  CBG’s equipment is designed for safe operation, including protection of end users operating our equipment.   All of our equipment comes complete with emergency shutoff capability.  This is coupled with the internal safety features, including temperature and level sensors, which interface with our programmer and controller, thereby providing additional safety in the design of our equipment.

Q. Is your equipment Class I Division I explosion proof?

CBG’s SRS I and SRS II Series are designed to be C1D2 compliant.   This is supported by the safety features described above.  

That said, CBG’s SRS I and SRS II Series can be fitted to include C1D1 capability.  This involves modifications to the wiring and certain electrical housings within the equipment.  Therefore, with a C1D1 unit in the SRS I and SRS II Series, there is a modest upcharge for the C1D1 capability for these reasons.

Q. What maintenance is required for the system?

In general, as is the case with most equipment, after operation, a cleaning of the contact parts (primarily the distillation tank) is required for CBG’s SRS I and SRS II Series.  CBG’s distillation tank is a double-wall tank, which includes thermal oil, which is used to heat the vessel.  In general, the thermal oil is recommended to be changed every 1,000 hours of operation.  This involves using a simple and easy to use flush solution, which is used to first clean the oil from the walls of the tank, while also cleaning the heating elements.  After the flush is performed, new thermal oil is filled into the tank for another 1,000 hours of operation. 

In addition, there are some contact parts which are recommended to be replaced on a periodic basis for the proper operation of CBG’s equipment.  In general, tank seals are recommended to be replaced every 6 months.  Otherwise, CBG’s equipment is built with rugged structure and contact parts and does not require significant maintenance. 

For our customers who want to have periodic maintenance, CBG offers Preventative Maintenance services in support of our equipment.  Oftentimes our customers will have CBG perform this on an annual basis or an every-other-year basis to promote effective and efficient use of CBG’s equipment.   

Q. Do you offer financing?

At the present time, CBG does not directly offer financing.   With customers, we do have flexibility with regard to payment terms and can work creatively with our customer to support our customers’ business objectives.  

Some of our customers do have financing partners.  CBG can work with your financing partners to bridge the financial needs of your company with your production needs by enabling and supporting the acquisition of CBG’s SRS Series equipment. 

Q. What does CBG’s SRS Series equipment enable me to do as an essential oils extractor?

CBG’s SRS Series equipment enables you to improve the rates of your solvent recovery as well as your Decarb processing.   Decarb processing is important and relevant prior to extraction, particularly CO2 extraction and enables you to increase your CO2 extraction efficiencies.   

In addition, post extraction oftentimes winterization is utilized.  CBG’s SRS Series equipment is often used post winterization to remove valuable ethanol (which can be recovered) and used for future processing and leaving the valuable oil/extract behind.

CBG’s SRS Series equipment can also be used to Decarb the extract/oil during the solvent removal process, should this capability be commensurate with your processing requirements.

EPD=R Systems

 

Q. What is the solvent throughput amount and what can the solvent recovery tank hold?  

The solvent will be distilled from CBG’s EPD=R System equipment at different rates of recovery, depending on the operating temperature.  CBG’s EPD=R System runs at a default operation temperature of approximately 70°C and has an approximate solvent recovery rate of roughly 2 gallons per hour.  In general, the rates of distillation are faster at the beginning of the process as compared to the end of the process when there is less solvent present in CBG’s distillation apparatus/unit.   

CBG’s solvent recovery tank aligns with the size of our distillation vessel.  CBG’s fractional distillation tank is 8 gallons and can hold 8 gallons of solvent for recovery.   

Q. What is the amount of solvent recovered per run?

The amount of solvent recovered per run can vary depending on the quantity of recoverable oil/extract or solids which may be present in the solvent when introduced into CBG’s distillation unit.  With that said, in general, solvent recovery volumes are 90-97%, depending on the amount of solids and/or extract/oil contained in the solvent when introduced into CBG’s distillation unit.

Q. What is the solvent output?

The solvent output from CBG’s unit is anywhere from 1.5 – 2.0 gallons per hour.   If an operator of CBG’s equipment can run on higher operating temperatures, meaning above 70°C, the rates of distillation and recovery of solvent will be greater – upwards of 3 gallons per hour recovery.  

 It should be noted that CBG’s equipment is versatile. CBG’s distillation equipment can be used for multiple solvent streams.  Therefore, if you, as our customer, are using pure ethanol, isopropyl alcohol and other carrier solvents in your operations, you have the ability and flexibility with CBG’s equipment to recover all of these solvents (by running separate processing runs with these individual solvents).   This improves yield, reduces your cost and aids the environment by recovering all organic solvents used in your operations.   

Q. How much solvent is left in my product after distillation?  

CBG’s fractional distillation apparatus is geared for industrial and higher throughput applications.   Our equipment is designed for demanding applications.   Our equipment maintains a rugged industrial design, which will stand up over time to your demanding and growing requirements.   

Assuming that oil/extract is introduced into our distillation unit together with ethanol, the amount of remaining ethanol in the product depends on your desired end product and its application.  We have customers that drive and utilize our equipment to “dryness.”  Other customers will retain residual ethanol in the oil/extract at the end of the process (removing in excess of 95% of the ethanol from the product) and then perform post processing steps which are appropriate for the oil/extract and its final end application.

Q. What are the electrical requirements?

In the case of CBG’s EPD=R unit, the electrical requirements are 220-240 V/1 PH/60Hz.  The Extraction Module will require one 10 amp power feed for the extraction tank and one 30 amp power feed for the chiller, a single standard 15amp 120V wall outlet will also be required for the Extraction Module.  The Purification Module will require one 15 amp power feed.  The Distillation Module will require one 30 amp power feed for the recycler. (Note: if we find that a second chiller is needed for the Distillation Module then a second 30 amp power feed will be required for the distillation module)

Q. What is the oil output?  

CBG’s EPD=R equipment uses ethanol as the main carrier solvent.  Ethanol is a tried and true solvent that has been used for centuries to craft tinctures, essential oils and similar substances.   In more modern times, alcohol is till among the most commonly deployed solvents.

Ethanol is non-toxic and is both a polar and non-polar compound, making the ideal solvent for botanical extraction.  

CBG’s automated 30 Liter/8 G Extractionmodules provide subzero temperatures to cool the plant material, while chilling the ethanol.   When the ethanol is lowered below freezing temperatures, its pickup of soluble components is substantially slowed and the ability to attach to frozen water based components is nearly eliminated.    

In accord, CBG’s automated purification module has been designed to preheat and filter the solution through your choice of activated carbon prior to distillation.   In general, CBG’s EPD=R Extraction yields are comparable to those used in BHO recovery and exceed those found in CO2 extraction.  

Q. What are your run times (start to finish) for EPD=R?

The run times will vary depending on the following variables, which are based on customer preference and your own processing and extraction requirements:

  • Wash time for the Biomass in Ethanol:  In general, our customers will perform the wash for a period of anywhere from 30 minutes to 120 minutes.  
  • Color requirements through and post Purification:  Through CBG’s Purification module, this purification step typically takes anywhere from 30 to 90 minutes depending on the customer’s desired color for the combination of oil/extract and solvent prior to being introduced into the distillation tank.
  • Running temperatures in distillation:  Depending on the running temperatures in the distillation vessel, distillation times will take anywhere from 4 hours to roughly 6 hours to end of process.    Therefore, CBG’s cycle time to perform a complete extraction, purification and distillation process along with recovery of solvent will take anywhere from a low of roughly 5 hours to a high of roughly 8 hours.  

It should be noted, as CBG’s EPD=R System is built in a modular configuration, as the Extraction is completed and this solution is transferred to the Purification vessel, the Extraction vessel can be recharged with fresh Biomass.  Thus, the system can run in cycles.  We have customers who process approximately 30 pounds of Biomass per day using this approach, which is built into the design of our equipment.  

Q. What type of biomass can I use in CBG’s EPD=R unit?  

It should be noted as CBG’s EPD=R unit is designed with rugged stainless steel construction, our equipment can be used to extract essential oils from:

  • Flower
  • Stem
  • Preprocessed material, for example product from a CO2 unit where additional oil/extract recovery and yield can be achieved through utilization of CBG’s EPD=R ethanol extraction technology.

It should be noted this is important and valuable to end users as our equipment can be utilized to extract oil from stem, which oftentimes is overlooked by processors or discarded.  The same can be indicated for flower product that is processed using a CO2 extractor.  CBG’s EPD=R ethanol extraction technology can be utilized to extract additional yield from that previously processed material, while recovering your valuable ethanol at the back end of our process and reuse.   

Q. Do you offer scalability?

Currently, CBG’s equipment is designed based on an 8 gallon platform. That is, CBG’s extraction vessel holds approximately 8 pounds of biomass (typically, in order to achieve this quantity, the biomass is milled prior to introduction into the extraction vessel). The purification tank is equipped to handle 8 gallons of solvent and our distillation equipment is also equipped to handle 8 gallons of solvent. This is supported by a recovery tank coming off of the back end of our fractional distillation equipment, which also holds 8 gallons of solvent.  Thus, the sizes for processing are aligned to afford the equipment to continuously cycle from extraction to purification to distillation to recovery and back to extraction with the recovered solvent.  

It should be noted that multiple processing runs can be achieved utilizing CBG’s EPD=R equipment. This is because as one step is completed, for example as extraction is completed, the extraction vessel can be recharged with fresh biomass and a second extraction process can be started as the first extraction is being processed through the purification step. This enables staging of your production and higher throughput.  Our customers are able to achieve extraction of roughly 30 pounds of biomass during a normal daily production schedule.

Q. Are the systems UL certified?

As it relates to the EPD=R System, CBG’s D or Distillation portion of this system is UL certified.  This is our fractional distillation capability, which is UL registered and UL certified.  Technically, the Extraction portion of our equipment and the Purification portion of our system is designed with the same intent as the distillation component to our system.   That said, at the present time, the Extraction module and the Purification module are not formally UL certified.   

Q. Is your equipment Class 1 Division 1 explosion proof?  

CBG’s EPD=R System is designed to be C1D2 compliant.   This is supported by the safety features described above.  

Q. What maintenance is required for the system?

In general, as is the case with most equipment, after operation, a cleaning of the contact parts (primarily the distillation tank), is required for CBG’s EPD=R System.  CBG’s distillation tank is a double-wall tank, which includes thermal oil, which is used to heat the vessel.  In general, the thermal oil is recommended to be changed every 1,000 hours of operation.  This involves using a simple and easy to use flush solution, which is used to first clean the oil from the walls of the tank, while also cleaning the heating elements.  After the flush is performed, new thermal oil is filled into the tank for another 1,000 hours of operation.
