Recovery pumps are used to move LPG's, liquified petroleum gases, between different parts of extraction systems. Recovery pumps are integral to the operation of many extraction facilities.
During hydrocarbon extraction, an LPG solvent (usually propane or butane) is used to extract the desired compounds from plant material. This creates a solution inside the hydrocarbon system that must be separated to collect the desired extract. The collection area of the hydrocarbon system is heated to turn the liquified gas into vapor and separate it from the desired compounds. A recovery pump is then used to move the vapor from the collection area and into a storage vessel. The recovery pump pulls the vapor out of the collection vessel and then pushes it through a condensing coil and into a proper storage vessel. The LPG solvent can then be used for further extractions.
