Shaanxi Coal and Chemical Industry Commends 12 Chemical Engineering Technologies

Thread Content

Recently, Shaanxi Coal and Chemical Industry Group Co., Ltd. awarded recognition and prizes for the new technologies in coal mining, gas management, and coal chemical processing that were developed independently over the past two years; 12 of these chemical technologies received awards for scientific and technological progress. Among the award-winning projects, the gas control technology for thick coal seams with high gas and oil content that are prone to spontaneous combustion won the Special Prize for Scientific and Technological Progress. The technology for producing acetic acid and acetic anhydride through multi-component carbonylation, the development of larger-scale methanol synthesis towers with uniform temperature control, and research on comprehensive gas utilization each received the First Prize. Eight other technologies, including those related to the technological upgrading of ammonia synthesis, won the Second and Third Prizes. Among them, the **\"11th Five-Year Plan\" scientific and technological research project carried out by the Tongchuan Mining Bureau – a technology for managing gas in thick coal seams with high gas content and oil and gas coexistence, which is prone to spontaneous combustion – achieved significant economic and social benefits, reaching an international advanced level; it won the second prize in the scientific and technological category awarded by the Coal Society in 2008 ； The sub-project research on dry coal powder pressurized gasification technology, part of the **\"863\" project undertaken by the Weihe Coal Chemical Group, contributed to the development of dry coal powder pressurized gasification technology with independent intellectual property rights in China, and won the first prize in science and technology in Shaanxi Province for the year 2007 ； The one-step synthesis of acetic anhydride with co-production of acetic acid, developed by the Coal Chemical Technology Center, breaks away from traditional acetic anhydride production methods, fills a gap in domestic technology, and achieves industrial application for the first time ； The scale-up technology for constant-temperature methanol synthesis towers developed by WeiHua Group has been adopted by various methanol manufacturers in China, opening up new avenues for the domestic production of large-scale methanol synthesis towers ； The synthetic ammonia technology upgrade project carried out by Shaanxi Chemical Industry Company involved expanding the gas generation and compression systems, which are key bottlenecks in fertilizer production, thereby optimizing the manufacturing process and reducing environmental pollution. Shaanxi Coal and Chemical Industry Group Company is the largest coal chemical enterprise in Shaanxi Province, and it has adopted a development strategy of \"one core and two wings\", with coal as the foundation and coal chemicals as the driving force, while pursuing diversified development. Over the past two years, Shaanxi Coal and Chemical Industry Group Corporation and its affiliated enterprises have strengthened cooperation with research institutions. Focusing on addressing key common technical issues such as those related to safety and production that hinder the development of these enterprises, they have prioritized scientific and technological research and innovation in areas such as coal mining, gas management and utilization, and coal conversion, thereby establishing a preliminary innovation mechanism that integrates industry, academia, and research.
