Abstract
A process is disclosed for producing from a pressurized methane-rich gas stream a pressurized methane-rich liquid stream having a temperature above -112.degree. C. (-170.degree. F.) and having a pressure sufficient for the liquid to be at or below its bubble point. In this process, a methane-rich liquid stream having a temperature below about -155.degree. C. (-247.degree. F.) is supplied and its pressure is increased. A pressurized methane-rich gas to be liquefied is supplied and introduced to the pressurized methane-rich liquid stream at a rate that produces a methane-rich liquid stream having a temperature above -112.degree. C. (-170.degree. F.) and a pressure sufficient for the liquid to be at or below its bubble point.
