Happy May Day 2024! Safety first. Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Rapid Development in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** At 15:18 on November 6, 2012, China’s first domestically produced 20-megawatt electric-driven compressor unit for natural gas pipelines (referred to as the 20-megawatt electric-driven compressor unit) was successfully commissioned at the Gaoling distribution compression station on the West-East Gas Pipeline Project Phase II. This marks the entry of the full domestic production of key equipment for long-distance pipelines in our country into the stage of industrial application, thereby breaking the passive situation of relying on imports for such products for a long time. 　　The electrically driven compression units for large-scale long-distance pipelines are the \"heart\" of natural gas transmission pipeline projects; in China’s field of natural gas transmission pipelines, they are comparable to the achievements related to the \"two bombs and one satellite\" program. Previously, only large enterprises in the United States, the United Kingdom, and Germany across the world were capable of designing, manufacturing, and assembling such components; they were also referred to in the industry as the \"pearls on the crown\" of the natural gas industry. For a long time, large-scale compression units in our country have been monopolized by foreign companies, resulting in high import prices and high maintenance costs. 　　On September 16, 2009, a leading group and working groups for promoting the domestic production of key equipment for long-distance natural gas pipelines were established. **Both China National Petroleum Corporation and other entities have established major scientific and technological initiatives, with the West-East Gas Pipeline Company taking the lead in efforts to develop domestic production of key equipment for long-distance gas pipelines. Under the unified leadership of the **Energy Administration and with the strong support of the China National Machinery Industry Federation, China National Petroleum Corporation, together with 10 other key enterprises in China’s mechanical and electrical manufacturing sector including Shenyang Blower Group, has, after two and a half years of intensive efforts, developed the first domestically produced compressor units for long-distance natural gas pipelines. All of the key technical specifications of these units meet international advanced standards. 　　The Gaoling off-take compressor station on the West Second Line is China’s first industrial test site for 20-megawatt electric drive compressor units, as well as the first pilot station for domestically produced compressor units in the country; it holds great significance and responsibility. Under the unified organization and leadership of CNPC, the Pipeline Construction Project Management Department and the West-East Gas Pipeline Company, along with workers from dozens of domestic enterprises involved in the project, took it upon themselves to promote the use of domestic components. After 6 months of hard work, they completed the construction of the first set of 20-megawatt electric-driven compressors at the Gaoling distribution compressor station on August 28, 2012, finishing the task 3 months ahead of the scheduled deadline. 　　The successful development and operation of 20-megawatt electric drive compressor units have greatly improved the overall technical level of compressor units used in China’s long-distance pipelines. They have broken foreign technological monopolies and trade barriers related to such equipment, promoted the development of various related industries, and contributed to ensuring energy security. As a key device in pipeline transportation systems, 20-megawatt electric drive compressor units have broad market prospects; each unit saves at least 20% more costs compared to imported compressors, and they can compete in the international market against foreign products. 　　The West Line 2 is equipped with a total of 7 sets of 20-megawatt electric drive compressors, of which 4 are located at the Gaoling distribution compressor station; these compressors operate on a \"3 in use + 1 standby\" configuration. As planned, the Gaoling distribution compressor station will draw fully on the experience gained during the installation and commissioning of the first set of 20-megawatt electric drive compressors, make continuous improvements, and then proceed with the construction and installation of the remaining three sets of 20-megawatt electric drive compressors. 　　After the first set of 20-megawatt electric drive compressors at the Gaoling distribution compression station is successfully ignited, a 24-hour test will be conducted. Followed by a surge line test, as well as a 72-hour load operation test and a 4,000-hour prolonged load operation test.
