An absorption process is disclosed for the recovery of normally liquid hydrocarbons from a gas stream. The process is useful in recovering hydrocarbons from the gas stream discharged by the main fractionation column of a fluidized catalytic cracking unit. The feed gas is compressed and passed through an absorption zone to produce a high pressure lean gas which is depressurized in a power recovery turbine. The turbine compresses air used within the catalyst regeneration zone of the fluidized catalytic cracking unit.
