Anqing Petrochemical Coal Gasification Plant adopts the core shell coal gasification technology in the world coal chemical industry, and is one of the three subsidiaries of Sinopec that use this technology. By relying on Sinopec's overall advantages and technology platform and strengthening cooperation with key universities and scientific research institutes, Anqing Petrochemical has absorbed and introduced the coal gasification technology and has made independent innovations. Several research and development achievements have been obtained by the State Intellectual Property Office. Patent authorization, and applied to industrial practice.
Shell coal gasification technology is the top technology in the field of coal chemical industry application. Most of its key equipment are imported. Among them, the carbon dioxide absorption tower methanol feed pump is a horizontal multi-stage centrifugal pump produced by U.S. High Quality Pump Company. The cost is high and the single rotor is as high as 650. About 10,000 yuan. If the pump is completely dependent on imports, it is not only costly, but also the reliability of equipment operation and the timeliness of spare parts procurement cannot be guaranteed.
To solve this problem and further promote the localization of coal chemical plant equipment, Anqing Petrochemical took advantage of the opportunity to repair the fertilizer plate, contacted the manufacturers to survey the rotors of the equipment, and conducted several technical exchanges to automate the problems in the use of imported rotors. Innovation and transformation. After two domestically produced rotor tests, the technical parameters were finalized and the adjustment was successful, achieving a successful drive.
On April 16, Anqing Petrochemical successfully reformed the rotor of the core component of the methanol feed pump of the CO2 absorption tower of the low temperature methanol wash unit of the coal gasification unit, and successfully started the drive once. This move changed the status of large-flow, high-lift, multi-stage pump-dependent imports of coal chemical plants, which not only reduced equipment manufacturing costs by 90%, but also further promoted the localization process of some imported coal chemical plant equipment, which has strong promotion and demonstration significance. .
