Abstract
There is disclosed a process and apparatus 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.
