Abstract
The present invention provides a process for recovery of propylene and LPG from the fuel gas produced in FCC unit by contacting a heavier hydrocarbon feed with FCC catalyst. The process provides an energy efficient configuration for revamping an existing unit constrained on wet gas compressor capacity or for designing a new gas concentration unit to recover propylene and LPG recovery beyond 97 mole %. The process of the present invention provides an increase propylene and LPG recovery without loading wet gas compressor with marginal increase in liquid loads.
