Description

Solvent Recovery Kit - 2 Gallon

The BVV Solvent Recovery Kit makes it easy for anyone to recover and reuse their extraction solvent. The kit uses a vacuum pump to lower the boiling point of the solvent, then will use a cooling source such as ice or dry ice to turn the vaporized solvent back into liquid form. This kit has a few different seals, be sure that all materials are compatible with your solvent. These materials include:

• Viton (FKM)
• Silicone
• EPDM / Butyl

Please verify before using that all these materials are compatible with your solvent. For an easy resistance chart please visit the Cole Parmer link below:

Not included in the kit, you will need:

• Ice Tray
  
• Ice Bucket
  
• Ice or dry ice

A 5 gallon bucket and disposable aluminum catering tray will suffice, however a container with a drain plug or valve would be ideal to easily drain the water produced throughout the process.

This kit requires a vacuum pump to operate, we would recommend a chemically resistant diaphragm vacuum pump. We include a 1/4" JIC and 1/4" barb connection to connect to your vacuum pump. The included hosing is 1/4" ID Tygon tubing to easily attach to a barbed vacuum pump.

Running the Unit

Caution: Unit uses flammable solvents. Use caution while operating unit. ALWAYS OPERATE IN EXTREMELY WELL VENTILATED AREAS

1. Place your solution into the Evaporating Vessel. This can be done by:
   1. removing the lid and pouring the solution into the vessel
   2. Using the vacuum pump to suck the liquid mixture through the Liquid Inlet Port. Using this method, you can use a Micro-Cap filter in-line to remove solid particulate.
2. Close the Liquid Inlet Port valve and Air Inlet valve
3. Add ice to the bucket and tray. A drain valve built in to the ice bucket and tray would help to drain water later in the test.
4. Open the Vacuum Pump valve and turn on the Vacuum Pump
5. Turn on the Heat Plate. An induction heating plate is recommended
6. Replace ice as needed throughout the run
7. When recovery is completed, close the Vacuum Pump valve and turn off the Vacuum Pump.
8. Open the Air Inlet valve and release the vacuum pressure from the chamber. Use the included micron filter to prevent contaminants from entering the vessel.
9. Turn off the Heat Plate and allow the solute in the Evaporating Vessel to come down to a safe temperature. Removing the solute is easiest when it is still warm.
10. Remove the solvent from the Receiving Vessel.
11. Once the kit is cooled down, use clean ethanol to wipe down the sealing surfaces for the next run.
