High-pressure pipe to lose natural gas in the city before the gas pipeline network, subject to pressure regulator station, resulting in a large number of cold process. The availability and utilization of cooling energy in pressure regulating process are analyzed. The method and integrated model of cascade utilization of process cooling energy and the implementation conditions and solutions for comprehensive utilization of process cooling energy are put forward.
