ABSTRACT:
A process and apparatus for recovering hydrocarbons from inert gas-hydrocarbon vapor mixtures wherein the mixture is caused to flow through a bed of solid adsorbent whereby the hydrocarbons are removed from the mixture and a residue gas stream comprised of substantially hydrocarbon-free inert gas is produced. A second bed of solid adsorbent having hydrocarbons previously adsorbed thereon is regenerated by evacuating the bed and the inert gas-hydrocarbon vapor mixture produced by the evacuation is contacted with a liquid absorbent whereby a major portion of the hydrocarbons are absorbed therefrom and recovered. The evacuation of the beds is accomplished using a vacuum pump with an integral cooling jacket for cooling the pump as well as the fluids pumped thereby attached thereto. A cooling medium such as the rich liquid absorbent produced in the process is caused to flow through the vacuum pump cooling jacket thereby cooling the pump and the inert gas-hydrocarbon mixture pumped thereby.
