On April 15, the lifting of the pulverized coal storage tank for the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (relocation and renovation) project, carried out by the Shanxi branch of China National Chemical Engineering Corporation’s 13th Construction Company, was successful, marking the project’s entry into the intensive pipeline installation phase. The coal powder storage tank to be lifted this time is the first custom-made equipment fabricated on-site. It is 18 meters tall and weighs 62 tons; its installation height is 60 meters. The lifting operation was carried out using an 800-ton crawler crane as the main lifting device, along with a 70-ton truck crane for assisting in the lift. The Clean and Efficient Gasification Gas Comprehensive Utilization Project in Jingyuan, Gansu, uses Jingyuan coal as raw material and employs pressurized gasification of coal using aerospace technology, as well as domestic isothermal shift processes, low-temperature methanol washing for desulfurization and decarbonization, liquid nitrogen washing for purification, and low-pressure ammonia synthesis to produce liquid ammonia, which is then used to manufacture urea, melamine, and other products. Project Review: The Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (Relocation and Renovation) project has a total investment of 5.425 billion yuan. It is located in the Yindong Industrial Park of the Baiyin High-Tech Industrial Park, covering an area of 839 mu. The raw coal and fuel coal used in the project are primarily Jingyuan coal, and advanced, mature, and energy-saving technologies such as pressurized coal gasification, isothermal shift, and Claus sulfur recovery are employed to produce products such as synthetic ammonia, methanol, urea, melamine, and urea solutions ； At the same time, it supplies high-quality raw materials such as hydrogen and carbon monoxide to other chemical enterprises in the Yindong Industrial Park, thereby promoting the development of a circular economy in the park. The designed production capacity is 2×300,000 tons of synthetic ammonia per year, 2×350,000 tons of urea, 100,000 tons of methanol, 216 million m3 of (H2+CO), 60,000 tons of melamine, 50,000 tons of urea solution, 50,000 tons of liquid CO2, and 2,500 tons of catalysts. The project uses 2 2,000-ton-class space gasification furnaces. The project is planned to be constructed in two phases. In the first phase, the main facility to be built is a pulverized coal gasification unit, along with newly installed facilities for air separation, raw gas conversion and purification, and ammonia synthesis. Upon completion of the project, it is expected that 1.725 million tons of raw coal can be processed on-site each year, enabling annual production capacities of 600,000 tons of synthetic ammonia, 700,000 tons of urea, 100,000 tons of methanol, 60,000 tons of melamine, and 50,000 tons of urea **solution. Once the project reaches full production capacity, it is expected to generate annual sales revenue of 2.7 billion yuan and total profits and taxes of 700 million yuan. On December 19, 2021, the pile foundation construction for the gasification unit of Phase I of the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (Relocation and Renovation) Project commenced.
