RESEARCH ON THE PROCESS FLOW OF NATURAL GAS DIFFERENTIAL PRESSURE POWER GENERATION SYSTEM

ABSTRACT
During the transmission of natural gas in the pipe-line network, the high pressure natural gas needs to be depressurized by the regulator station and enter the low pressure pipe-line, and the depressurization process will release a lot of pressure energy. At present, some scholars and enterprises have begun to use turbine ex­panders to convert excess natural gas pressure energy into electricity. However, with the different working conditions of different regulator stations, there are dif­ferences in the use of pressure energy. In this paper, energy analysis of energy power generation process of a city gate station was applied to optimize the design of energy power generation process. This works provide a method for natural gas pressure power generation process design.
