Abstract:
A process for recovering liquefied petroleum gas from tail gas includes recovering a tail gas stream from a pressure swing adsorption zone and contacting the tail gas stream with a sponge liquid such as an unstabilized reformate liquid stream in order to recover C3+ hydrocarbons from the tail gas stream. The C3+ hydrocarbons may be recovered from the sponge liquid as liquefied petroleum gas.
