 Apparatus for ethane liquefaction patent thumbnailApparatus for ethane liquefaction
The apparatus for ethane liquefaction can include a mixed refrigerant refrigeration cycle having inline compression without interstage cooling, or cooling only after the first compression stages where there is no liquid formation yet, such that the number of liquid recycle loops are reduced. The lack of cooling in the compressor reduces the compressor's mechanical efficiency; however, this is offset by having a more thermodynamically efficient process cycle because the cycle can operate as a mixed refrigerant rather than cascade..
