| Abstract: | In view of the low exergy efficiency of BOG(boil-off gas) reliquefaction plant in LEG(liquefied ethylene gas) vessels,the current process was optimized.Exergy analysis of ethylene BOG reliquefaction system and refrigerant cycle system was carried out based on a detailed thermodynamic analysis of current and optimized process.The results show that the exergy efficiency of the optimized process is 29%,and it is 9.6% higher than that of the current process which is 26.5%. |
