Aghili, H K

A process is described for separating the constituents of a natural gas stream comprising: (a) lowering the temperature of the gas stream; (b) supplying the lower temperature gas stream to a high pressure separator, the high pressure separator separating the gas stream into predominantly vapor and predominantly fluid streams; (c) lowering the pressure of the predominantly vapor stream; (d) supplying the lower pressure vapor stream to an upper region of a demethanizer column; (e) lowering the pressure of the predominantly fluid stream; (f) supplying the lower pressure fluid stream to the demethanizer column at an elevation below the vapor stream; (g) removing cold vapor residue gas from an upper region of the demethanizer column.
