Abstract

The unconventional natural gas is very abundant in China. Small scale natural gas liquefiers can be effectively used for the extraction of the unconventional natural gas with a very promising future. In this study

a small scale auto-cascade natural gas liquefier using a rectifying column was simulated by HYSYS®. The influence of compositions of refrigerant mixtures on the energy consumption for the liquefaction of per unit LNG and the discharge temperature of the liquefier

was analyzed. Concentrations of the refrigerant mixtures were optimized and the optimum concentrations for the specified operating condition were obtained. The temperature profiles of three recuperators in the system with the optimum concentrations were also investigated to analyze the efficiency elevation of the system.
