Abstract
The processing of gas streams containing hydrocarbons and other gases of similar volatility to recover high yields of components such as ethane, propane, and heavier hydrocarbons therefrom by expanding said gas stream in at least two stages through turboexpanders, each stage cooling the gas stream and producing energy in the form of horsepower used to drive a recompressor unit or other mechanical apparatus. Condensed liquids are collected intermediate the expansion stages. Preferably, a supplemental gas cooling stage and condensed liquid recovery occurs following each expansion stage.
