Lenticular Filtration Set-up and Operation For Polishing Crude/ Winterizing

      Setting up Lenticular Filter:

  1. Screw in the center post to the housing of the filter - Make sure it's tight and secure.
  2. Install backflush plate onto the center post.
  3. Place lenticular filter over the post so that its resting on backflush plate.
  4. Install the compression spring onto the center post and screw on tight. The flat gaskets on the filter will seal once the compression spring has been screwed on tight.
  5. Install the top housing onto the bottom housing of the filter and tighten the screw-down clamps.

Operating the Lenticular Filter For Polishing:

  1. Mix adsorbents into alcohol solution. Stir in solution for at least 20 minutes and then let solution sit for a minimum of 45 minutes (This process should take about an hour at the least, but may require some trial & error to discern the proper time based on input material).
  2. Attach hose from mixing vessel (keg, reactor tank, etc.) to inlet valve on lenticular filter.
  3. Open the the inlet valve and and outlet vent on the top of the lenticular filter.
  4. Begin flow of the ethanol solution into the system. Use pressurized keg/reactor OR a non-pulsing pump to push fluid through filter.
  5. Once the solution has reached the top sight glass on the filter, close the outlet vent and then open the outlet valve.
  6. When the solution is finished going through the filter close the outlet valve and inlet valve.
  7. Open the outlet vent on the top of the housing to release any pressure in the system.
  8. On the bottom housing, open the drain valve and drain any leftover solution from the filter.
  9. After the hoses are removed, drain any leftover solution that is still inside the inlet and outlet valves on the system. There may be .5 - 1 gallon(s) of solution that is residual in the system. This can be added to the next extraction if the material is the same, or to some sort of a “house blend” if processing several different types of biomass.
  10. After you have drained the system, take it apart completely in reverse of the way it was assembled. Place the filter in storage for later use and wipe down the system housing of any absorbents that may inside the housing or in the inlet valve. Rinse/wipe down the equipment with clean alcohol to ensure no contamination on future use.

Operating The Lenticular Filter for Winterization:

  1. Attach the hoses from kegs that have been de-waxed to inlet of valve on the lenticular filter.
  2. Open the inlet valve and outlet vent on the top of the lenticular filter.
  3. Begin flow of the alcohol solution into the system.
  4. Once the solution has reached the top sight glass on the filter, close the outlet vent and open the outlet valve.
  5. When the solution is finished going through the filter close the outlet valve and inlet valve.
  6. Open the outlet vent on the top of the housing to release any pressure in the system.
  7. On the bottom housing open the drain valve and drain any leftover solution in the filter.
    After the hoses are removed drain any leftover solution that is still inside the inlet and outlet valves on the system. There will be .5 - 1 gallon(s) of solution that is residual in the system. This can be added to the next extraction if the material is the same, or to some sort of a
    “house blend” if processing several different types of biomass.
  8. Once the system is drained its very important to disassemble the the lenticular filter quickly and get the filter out of the housing and into a freezer. This will prevent the waxes from warming up and soiling the filter.
  9. Wipe down the system housing of any waxes that may inside the housing or in the inlet valve. Rinse/wipe down the equipment with clean alcohol to ensure no contamination on future use.
