The scheme uses a 3 stage compressor wherein {TAIL ~ at least a portion} of the high pressure liquid from the high pressure flash zone is used in {HEAD ~ a solvent recovery step} to remove lean solvent from a combined stream of the compressed low and medium pressure off gases in the high pressure flash zone to reduce overall solvent losses from the process
