Abstract
A process for the recovery of hydrocarbon vapors from an air-hydrocarbon mixture wherein the inlet air-hydrocarbon mixture is passed to an absorber vessel in which is fed a vacuum flashed liquid hydrocarbon absorbent to produce an absorber overhead gas stream which is passed to a solid absorbent bed. Once saturated, the adsorbed hydrocarbon on the solid adsorbent bed is removed by liquid vacuum pump regeneration, separated from the pump liquid, and returned to the system for use. Hydrocarbon free air is vented from the solid adsorbent bed during the adsorption mode.
