·
OSTI ID:7117435
A process and apparatus disclosed for recovering ethane and heavier hydrocarbons from natural gas by heating the natural gas stream prior to the expansion and introduction thereof into a demethanizer operating under cryogenic conditions. Ethane and the heavier hydrocarbons are recovered from the demethanizer as well as a residual gaseous methane stream which is compressed to a pipeline receiving pressure by the work of expansion without requiring a booster compressor. 10 claims, 1 drawing figure.
