The expansion refrigeration process, characterized by simple configuration, low investment, quick start, easy operation, good adaptability and energy-saving for natural gas expansion by taking advantage of pipe pressure differences, is widely used in small and medium-sized LNG plants.
Expander refrigeration cycle(basing on various types of refrigerants, it can be classfied in nitrogen expander refrigeration cycle, N-CH4 expander refrigeration cycle and natural gas expander refrigeration cycle)is to achieve liquefaction of natural gas by the use of Claude cycle refrigeration through high-pressure refrigerant adiabatic expansion in turbo expander.
After being compressed in refrigerant compressor, refrigerant is supercharged by expander supercharging side. Then it goes into liquefaction heat exchanger for cooling. Before reheating and entering into refrigerant compressor, refrigerant expands in expander and returns to liquefaction heat exchanger to provide cold energy. Refrigeration cycle forms through this process.
In order to lower energy consumption of expander liquefaction process, an ammonia-freon-propane precooling cycle is added at the high temperature section of the liquefation heat exchanger.
