Abstract

Ethane is removed from a feedstream comprising methane, ethane and higher components by dividing the feedstream and passing one stream directly to the de-ethanizer with the other stream being passed to a stabilizer in order to remove the heavier components of the natural gas stream. The overhead vapor from the stabilizer is then passed to the de-ethanizer. The overhead vapor stream passed to the de-ethanizer from the stabilizer can also be cooled in order to reduce the refrigeration load of the de-ethanizer.
