OPTIMIZATION OF REFRIGERANT COMPOSITION OF LOW-TEMPERATURE STAGE OF DUAL MIXED REFRIGERANT CYCLE

摘要

The results of optimization of low-temperature refrigerant composition in dual mixed refrigerant cycle by mathematical-analytical method using performance data for increasing liquefied natural gas (LNG) production and decreasing specific energy consumption are reported. The flow diagram of the LNG cycle with dual mixed refrigerant is presented. The advantages of using dual mixed refrigerant cycle are shown.
