| Abstract: | The high pressure pipe networks of city gas contain huge pressure energy. Based on the technology analysis of natural gas transmission and distribution system, the recovery method and application direction about pressure energy from the loss are discussed. It is proposed that the screw expander changes the pressure energy into electricity with pressure difference of high pressure regulator stations. The technological superiority and key technology of screw expander are described. The application example has proved the security and feasibility of the power genera- tion technology with screw expander, which makes up for the defects of turbomachinery and is worth promoting in the natural gas pressure energy recovery and expansion refrigeration technol- ogy. |

| Keywords: | screw expander pressure energy recovery power generation system sealing sys-tem control system |
