Abstract (en)
A hydrocarbon feed stream is passed to an extraction column. A recycle portion of the liquid bottom stream withdrawn from the extraction column is recycled back into the extraction column, whereby the recycle portion enters the extraction column in liquid phase. The recycle portion has the same composition as the liquid bottom stream being withdrawn from the extraction column. A vaporous overhead stream is withdrawn from the extraction column, from which a lean methane-containing gas stream is produced.
