Objective During the transportation of natural gas, in order to meet the downstream pressure conditions, it is necessary to further regulate the pressure. If this part of pressure can be effectively recycled, it is of great significance to improve economic benefits and reduce environmental pollution. Methods Based on the differential pressure power generation project of PetroChina Southwest Oil & Gasfield Company, this paper introduced the process flow of differential pressure power generation of the imported branch in detail, and optimized the equipment selection on this basis. Through data comparison, the performance change of the differential pressure power generation system is analyzed. Results The main influencing parameters are determined to be the inlet temperature of the product gas, the pressure ratio between the inlet and outlet, and the internal loss of the turbine expander. By adding a preheater to appropriately increase the inlet temperature of the product gas, increase the pressure ratio between the inlet and outlet, and replace key components in a timely manner, the power generation efficiency can be effectively improved. Conclusions This research not only provides direction for optimizing the performance of natural gas pressure differential power generation and selecting key equipment, but also provides a theoretical and practical basis for subsequent research while pioneering a new field of differential pressure power generation in the natural gas purification industry.
