Core Viewpoint - The first high-pressure natural gas long-distance pipeline pressure recovery power generation project in China has officially commenced operations in Jiangsu Nantong, marking a breakthrough in the comprehensive utilization of energy in long-distance pipelines [1][3]. Group 1: Project Overview - The Hai Men Station natural gas pressure recovery power generation project efficiently utilizes excess pressure resources during high-pressure natural gas transportation, converting pressure potential into mechanical energy to generate clean electricity [1]. - The project is expected to generate approximately 3 million kilowatt-hours of electricity annually, equivalent to reducing carbon dioxide emissions by over 2000 tons [1]. Group 2: Technological Innovations - The core equipment for the power generation project has been independently developed and manufactured in China, featuring adjustable flow technology and 3D-printed impellers, which enhance the efficiency of low-temperature natural gas reheating while significantly reducing the equipment's own energy consumption [3]. - The new equipment operates in parallel with the existing pressure regulation system, ensuring a reliable gas supply for residents and businesses even if the power generation equipment is offline [3]. Group 3: Future Plans - The company plans to gradually promote megawatt-level domestically produced pressure recovery power generation equipment in typical distribution stations in the Yangtze River Delta region [5]. - It is estimated that the total installed capacity of high-pressure natural gas long-distance pipeline pressure recovery power generation projects in China will reach 42,000 kilowatts under the natural gas self-reheating scheme [5].
