Research on Current Status and Prospects of LNG Cryogenic Energy Utilization

The application of liquefied natural gas in our country kept fast growth year by year, while the use of cold energy of LNG has the vital significance to save energy, lower energy consumption and reduce pollutants discharge. Cold energy of LNG not only has feature of the high density but also of extensiveness of temperature distribution. This article unifies lots of domestic and foreign material to start with the purpose and significance of cold energy of LNG summarizes the current usability and features of cold energy of LNG According to the thermodynamics, this article forwards the concept and computational method of evaluation the cold energy of LNG, summarizes the methods and strategies of comprehensive utilization of cold energy of LNG, and also from four aspects of using precautions of cold energy of LNG including the temperature limits, dosage limits factory location, and security restrictions. Finally, the prospects using of cold energy of LNG in our country were analyzed and predicted.
