ABSTRACT:
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 by upward passage through an absorption zone. Resultant rich oil passes to a stripping zone and then to a fractionation zone. A first lean oil is withdrawn from fractionation zone bottoms and enters the absorption zone superior to the entry of a second lean oil. The second lean oil is withdrawn from the stripping zone and passed to the absorption zone. A stripped vapor is withdrawn from the stripping zone and is mixed with the feed. This mixture is partially condensed in a cooling zone and then separated into liquid and vapor phases in a separation zone. The vapor phase is then withdrawn from the separation zone and is introduced adjacent the lowermost point of the absorption zone. The liquid phase is withdrawn from the separation zone and is introduced into the absorption zone at an elevation superior to that of the introduction of the vapor phase.
