Semi-rich amine liquid pump for high sulfur natural gas purification plant

   The high-pressure multistage centrifugal pump of the high-sulfur natural gas purification device of Zhongyuan Oilfield Branch (Puguang Branch) won the third prize of Liaoning Science and Technology Progress Award in 2022 (Liaoning Provincial Science and Technology Progress Award) Zhengfa [2023] No. 10).

   As one of the major national projects of the State Council during the Eleventh Five-Year Plan period, the Puguang Gas FieldSichuan-East Gas Transmission"The main gas supply source of the project, high-sulfur natural gas is purified and transported to more than 70 cities in eight provinces (cities), covering a population of more than 200 million and thousands of enterprises. The social and economic benefits are huge. Natural gas in Puguang Gas Field The pumps used in the high-sulfur natural gas purification device of the purification plant all use imported equipment such as EBARA and Flowserve, which are internationally renowned. There are problems such as long procurement cycle, high price, and technical monopoly of the manufacturer. In addition, the design process parameters are not consistent with the actual operating conditions on site. There is a large deviation, which leads to high energy consumption of the unit, seriously affects the smooth operation of the natural gas purification plant, and restricts my country's "Sichuan-East Gas Transmission"Engineering Energy Construction.

   Shenyang Blower Group Petrochemical Pump Co., Ltd., Shenyang Blower Group Co., Ltd. and Sinopec Zhongyuan Oilfield Branch worked together to focus on actual operating conditions on site, anti-cavitation, docking problems between old and new units, anti-scratch, safe and stable operation A series of key technological breakthroughs have been carried out, and the "semi-rich amine liquid pump for purification of high-sulfur natural gas" has been successfully developed to achieve localized manufacturing. At present, the purification plant of Puguang Gas Field in Zhongyuan Oilfield has been put into operation, and the unit is running stably and reliably. The research and development of this project has filled the gap in the technical field of similar natural gas purification equipment in China. After the appraisal of the Science and Technology Achievement Evaluation Center of Zhongke Hechuang (Beijing), the localization of semi-rich amine liquid pumps for high-sulfur natural gas purification equipment has reached the international level. advanced.

   The project was successfully developed forUsers save a lot of construction funds, save a lot of foreign exchange for the country, and break the monopoly of foreign technology. In the future, the country will build new natural gas purification devices in Southwest China, Iraq and other places, which has broad application prospects.
