摘要

Abstract of the DisclosureA process is disclosed for the recovery of ethaneand heavier hydrocarbons from a methane-rich gas utilizingan expander, a high pressure demethanizer tower with flashedand expanded vapor and liquid streams, as coolants in heatexchange relationship with the processed hydrocarbon vapors.
