Gansu LiuHua Group is constructing a clean and efficient coal-to-gas comprehensive utilization project in the Yindong Industrial Park of the Baiyin High-Tech Industrial Park. This project serves as an important foundation and support for the group company to achieve high-quality development, by expanding through the coal-electricity-chemical industry chain, further optimizing the industrial structure, and promoting the adjustment and improvement of both the economic and industrial frameworks. The comprehensive planning and investment for the production of clean and efficient coal-based gas amount to around 5 billion yuan. Jingyuan coal is used as the primary raw material, and advanced and mature technologies such as pressurized coal gasification, isothermal shift reaction, low-temperature methanol washing, Claus sulfur recovery, liquid nitrogen washing, low-pressure ammonia synthesis, and CO2 stripping for urea production are employed to manufacture products such as synthetic ammonia, methanol, urea, nitric acid, nitro compound fertilizers, melamine, and urea solutions ； At the same time, it supplies high-quality raw materials such as hydrogen and carbon monoxide to other chemical enterprises, thereby forming an upstream and downstream industrial chain that maximizes resource utilization and minimizes pollutant emissions, thus promoting the development of a circular economy in the park. Upon completion of the project, it will be possible to convert approximately 1.8 million tons of raw coal into useful products each year. This will enable annual production of 600,000 tons of synthetic ammonia, 700,000 tons of urea, 100,000 tons of methanol, 150,000 tons of concentrated nitric acid, 250,000 tons of nitrogen-based fertilizers, 216 million Nm3 of (CO+H2) gas, 60,000 tons of melamine, 50,000 tons of urea solutions, and 50,000 tons of food-grade liquid CO2. In addition, liquid oxygen, liquid nitrogen, liquid argon, and catalysts will also be produced. This will facilitate a transformation in the raw material sources used for fertilizer production as well as an upgrade of the industrial structure. By extending the coal-based industrial chain, Jingmei Group can increase the added value of coal products and improve the efficiency of utilizing coal resources. The industrial structure will be further optimized, thereby creating a modern circular economy system that integrates coal, electricity, and chemical production, enabling the company to achieve sustainable development of high quality. Once the project reaches full capacity, it will have significant practical importance in promoting the social and economic development of the entire province. The project feasibility study report was prepared by the Lanzhou branch of Aerospace Changzheng Chemical Engineering Co., Ltd., and it passed the evaluation by an expert panel on September 19, 2018. The preliminary work for the project was approved at the first interim meeting of the third board of directors of Jingmei Group in 2019. The Provincial State-owned Assets Supervision and Administration Commission issued its approval on March 28, 2019; Gansu Energy and Chemical Investment Group Co., Ltd. approved the initiation of preliminary work on April 2, and the project was registered with the Economic Development Bureau of Baiyin High-tech Zone on June 28. The project’s safety assessment, environmental impact assessment, energy assessment, and geological survey tasks have had their winning contractors determined through public bidding conducted by the Gansu Province Bidding Center; all of these tasks are now in full swing. Meanwhile, efforts related to water supply, power supply, dedicated railway lines, and financing discussions are also being coordinated thoroughly. The project is scheduled to be ready for construction by the end of 2019, with the main production lines for synthetic ammonia, urea, methanol, etc. set to be completed and put into operation in the second half of 2021.
