Research on High Efficient Utilization of LNG Cold Energy

Liquefied natural gas (LNG) contains a large amount of cold energy.The development of cascade utilization of LNG cold energy has large economic benefits, and it is beneficial to reduce the cost of LNG.This paper designed a process and simulated the utilization system of LNG cold energy based on the software Aspen plusin order to utilize the cold energy reasonable.The simulation results show that the cascade utilization system is rationalwhich unites the process of cryogenic comminution of waste rubber, production of liquid CO 2 and dryice, and cold storage.The cascade utilization of LNG cold energy increases the utilization efficiency of LNG cold energy greatly, and it can also save energy.
