Progress and Prospect of LNG Cold Energy Utilization in China

Values and utilization significance of LNG cold energy LNG is a cryogenic liquid mixture made from gas through purification and liquefaction at the temperature of 162℃.850 kWh/t of power may be consumed for LNG production.230kWh/t of cold energy with the temperature ranging from-162℃ to 5℃ may be released when LNG is gasified under the pressure of latm.During actual gasification operation,pumps are required to be used to increase pressure for LNG gasification and delivery,so part of LNG cold energy will be converted into pressure energy(Fig.1).
