Abstract
A self-stripping, recycling adsorbing unit for recovery of hydrocarbons from a mixture of hydrocarbon vapors and air, including two adsorbers filled with adsorbent material, automatically controlled valves which route the mixed vapor flow through one adsorber and connect the other to a stripping apparatus, and instrumentation which automatically determines when the flows through the adsorbers should be interchanged and which activates the automatic valves to accomplish this interchange. The stripping apparatus includes a compressor with suction arranged to alternately evacuate the adsorbers and with its discharge connected to a condenser. Condensed hydrocarbon is sent to storage and uncondensed vapors are recycled through the active adsorber together with mixed air and hydrocarbon vapors entering the system for processing. An alternative means of stripping the adsorbers utilizes the compressor, condenser and related equipment from an existing vapor recovery system to which the adsorbers may be connected for stripping. Modifications to the existing system include instrumention to provide for and restrict the use of existing components for stripping the adsorbers to time intervals when such components are otherwise inactive. In further embodiments, the compressor output is periodically routed through selected adsorbers, heating the adsorber selected for regeneration whereby the adsorber is warmed up to induce evaporation of the hydrocarbon collected therein.
