At 15:58 on February 25, the first phase of the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (Relocation and Transformation) project successfully produced urea, marking the completion of the entire main production line for ammonia and urea in this phase. The urea production unit of this project utilizes a new carbon dioxide stripping process, with a designed hourly output of 54.16 tons. It comprises processes such as carbon dioxide compression, supply of liquid ammonia as raw material, urea synthesis, low-pressure decomposition and recovery, vacuum concentration of the urea solution, two-stage evaporation, and desorption-hydrolysis of the process condensate. The urea produced features high purity, low biuret content, and stable quality. The exhaust gas from the granulation tower is treated using dry dust removal technology to ensure it meets emission standards. The Gansu Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization Project uses Jingyuan coal as raw material and employs pressurized gasification technology. The first phase of this project enables an annual production capacity of 300,000 tons of synthetic ammonia, 350,000 tons of urea, 20,000 m3/h of (H2+CO), 40,000 tons of methanol, 50,000 tons of liquid carbon dioxide, 60,000 tons of melamine, 50,000 tons of urea-ammonium solution, 1,924 tons of sulfur, and 2,500 tons of catalysts. Project Overview: 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 ammonium nitrate solution ； 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 first phase of the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization Project has an annual production capacity of 300,000 tons of synthetic ammonia, 350,000 tons of urea, 20,000 m3/h of (H2+CO), 40,000 tons of methanol, 50,000 tons of liquid carbon dioxide, 60,000 tons of melamine, 50,000 tons of urea-ammonium solution, 1,924 tons of sulfur, and 2,500 tons of catalysts. The second phase of the project results in an annual production capacity of 300,000 tons of synthetic ammonia, 350,000 tons of urea, 10,000 m3/h of (H2+CO), and 60,000 tons of methanol.
