Abstract
A process is described for the separation and recovery of C.sub.3 and heavier hydrocarbons from a gaseous hydrocarbon containing feed stream such as natural gas or refinery gas in which the gaseous feed stream is cryogenically expanded and the expanded gas is brought into contact with an absorption medium. The C.sub.3 and heavier components are liquefied and subsequently subjected to distillation and recovered as liquid product.
