ABSTRACT OF THE DISCLOSURE Process with improved efficacy for the separation and recovery of desired liquid and vapor constituents from a feed stream containing such constituents. The feed stream is contacted with two separate and distinct lean oils in an ab- sorption zone. Resultant rich oil passes to a stripping zone and then to a fractionation zones. A first lean oil is with- drawn from fractionation zone bottoms and enters the absorp- tion zone superior to the entry of a second lean oil. The second lean oil is withdrawn from the stripping zone and passed to the absorption zone. One preferred embodiment is found in the recovery of LPG and stabilized gasoline from liquid and vaporous products of a fluid catalytic cracking process.
