At 9 a.m. on April 24th, the main framework of the urea packaging building for this project was completed, laying a solid foundation for its early completion and operation. The successful completion of the main framework construction for the urea packaging building represents another important milestone in this project, indicating a partial success in its construction and signaling that it is about to enter the phase of equipment installation. The project is expected to be completed by November 30. It is understood that the urea packaging building for this project began construction in November 2022. It was designed by China Fifth Ring Engineering Co., Ltd. and built by Thirteen Chemical Construction Company. The building covers an area of 935㎡, has a construction area of 4574㎡, 8 floors, and a height of 39.8 meters. The urea packaging building of this project is equipped with 8 fully automatic packaging lines for the continuous packaging of urea finished products, with each line having a production capacity of ~800 bags/h. One semi-automatic packaging line is set up for the centralized packaging of urea powder that has been screened and dust-freeed, while another ton bag packaging line is used to package the finished urea product. Shaanxi Longhua Gasification uses 3 Jinhua furnaces. The project is scheduled for the handover of the urea plant on September 30, 2023, and the handover of the ammonia synthesis plant on October 30, 2023. The gasification unit of the project for the clean, efficient, and comprehensive utilization of coal at different grades and qualities adopts the slurry-cooled wall directly-connected waste boiler gasifier technology (Jinhua Furnace 3.0) developed by Beijing Qingchuang Jinhua Technology Co., Ltd., replacing the existing atmospheric pressure fixed-bed gasification system. There are 3 gasifiers in total. The gasifier operates in a two-in-one-backup configuration. The vaporization pressure is 6.5 MPaG, with a total gas flow rate of 204,000 Nm3/h (CO + H2); high-pressure steam at 10.0 MPaG is produced as a by-product. The single furnace can produce 102,000 m3/h of effective gas. The daily coal input is 1,765 tons. The load regulation range of the gasifier is 60% to 110% of its designed capacity. Project Overview: The Shaanxi Coal Longhua Mining Project aims for the clean and efficient utilization of coal on a differentiated basis. It involves the production of 500,000 tons per year of synthetic ammonia, 800,000 tons per year of urea, 300,000 tons per year of calcium carbide, 1 million tons per year of lignite coke, 300,000 tons per year of lime, 60,000 tons per year of melamine, as well as 50,000 tons per year of LNG. The project utilizes advanced, mature, and reliable technologies such as clean coal gasification, ammonia synthesis, low-temperature methanol washing, sulfur recovery, isothermal shift, and liquid nitrogen washing to produce synthetic ammonia, which is then used as a raw material to manufacture products such as urea and melamine. The total investment for the project is 7.07 billion yuan. The project for the clean and efficient utilization of coal at different grades and qualities in Shaanxi Coal Longhua Mining was halted in September 2021 due to the failure to obtain approval for energy-saving assessments. Once the project for the clean, efficient, and comprehensive utilization of coal based on grading and quality classification is completed, the coal processed at the company’s coal washing plant will be sent to gasifiers for the production of synthetic ammonia. The combustible gases such as methane that remain after synthetic ammonia production, along with coal sludge and gangue, will be used as fuel in power plants to generate electricity. The electricity, heat, and steam produced by these power plants will be supplied to coal mines and chemical plants for use ； Ammonia is ultimately used to produce urea. A complete industrial chain from coal to synthetic ammonia and then to urea products has been established, representing a transition from \"black\" to \"white\". This project is an integrated utilization initiative planned, prepared for, and put into operation by Shaanxi Coal Longhua Mining Company as part of its commitment to implementing Shaanxi Coal Group’s five-carbon development strategy of \"carbon preservation, carbon removal, carbon reduction, carbon sequestration, and carbon transformation.\" By leveraging its own coal resources, the company aims to develop a high-end fine chemical industry chain and advance the concept of \"using coal from start to finish.\"
