<p>A pressure swing adsorption process and method using a vacuum pump (4) to desorb organic vapors from an adsorption bed (11) and then a liquid-ring compressor (27) to compress the desorbed vapor stream to a pressure above atmospheric pressure to better recover compounds that have an atmospheric pressure boiling point below thirty five degrees centigrade. The process is especially suitable for recovering gasoline vapors from the headspace of a gasoline tank when the tank is being filled.</p> |
