Summary Introduction
The total mileage of long-distance natural gas pipelines in operation in my country will reach 76000 kilometers, and the total gas transmission capacity of trunk pipelines will reach 350 billion cubic meters per year. China's natural gas pipeline network mostly adopts the way of cascade supply, the main line-provincial network-municipal high-pressure pipeline (4 MPa)-first-class city combustion-second-class city combustion-industrial park franchise. The transmission of natural gas from high pressure to low pressure, and finally to the ultimate user, generally take the throttle decompression, resulting in a lot of energy waste.

MessageDetails Introduction
The total mileage of long-distance natural gas pipelines in operation in my country will reach 76000 kilometers, and the total gas transmission capacity of trunk pipelines will reach 350 billion cubic meters per year. China's natural gas pipeline network mostly adopts the way of cascade supply, the main line-provincial network-municipal high-pressure pipeline (4 MPa)-first-class city combustion-second-class city combustion-industrial park franchise. The transmission of natural gas from high pressure to low pressure, and finally to the ultimate user, generally take the throttle decompression, resulting in a lot of energy waste.
Natural gas expansion power generation and cold energy recovery system, including screw expansion generator set, heat pump heat supplement system, cold energy comprehensive recovery system, etc. The high-pressure natural gas in the upstream pipeline enters the screw expansion generator unit through the bypass pipeline, and enters the lower-level urban pipe network after single-stage or double-stage isentropic expansion. During the expansion process, the screw expander drives the generator to generate stable electric energy, and the cold energy generated during the expansion process is transmitted to the ice making, air conditioning, refrigeration, refrigeration and other cooling units through the refrigerant circulation system. The heat pump supplemental heating system simultaneously heats the natural gas to the specification requirements. The high-pressure natural gas from the upstream enters the natural gas expansion generator set through the bypass pipeline, and after one or two stages of expansion, the pressure drops to the required pressure, and returns to the main road to enter the lower municipal pipeline network. During the expansion process, the generator is driven to generate electricity. The expanded low-temperature natural gas is heated by the refrigerant, and the outlet temperature rises above 5 ℃ to prevent ice blockage and ensure the safety of the natural gas pipeline network. The refrigerant circulation system transfers the heat energy generated by the heat pump refrigeration system to the natural gas, and at the same time transfers the cold energy generated during the expansion of the natural gas to the heat pump refrigeration system, and the refrigeration system recovers the cold energy for refrigeration.
