Shaanxi Longhua Group Coal Technology Development Co., Ltd.'s coal classification, quality, clean, efficient and comprehensive utilization project is fully rolled out Author/Source: Chemical Network Coal Chemical Industry Date: 2022-06-26 Click rate: 31 Since the project resumption mobilization meeting was held on May 20, the coal classification, quality, clean, efficient and comprehensive utilization project of Shaanxi Longhua Group Coal Technology Development Co., Ltd. has been fully launched. It is reported that since June, the project has held 27 online and offline discussions and exchanges with design institutes, construction units, and equipment units, focusing on how to control the quality, construction period, and cost of the project through contracts, and how to ensure that the project quality meets expectations under the EPC general contracting model and a fixed total price; how to ensure that the main equipment and materials meet the owner's requirements; how to control changes in the contract price caused by the owner's initiative to change the design, etc., laying a solid foundation for the signing of the next commercial and technical contract. According to the person in charge of project safety, the second batch of project boiler equipment has arrived at the site, with 283 construction personnel and 51 excavator loaders, drilling rigs, tank trucks and other construction machinery on site. On May 20, a mobilization meeting for the resumption of work of the coal classification, quality, clean, efficient and comprehensive utilization project of Shaanxi Longhua Group Coal Science and Technology Development Co., Ltd. was held. The total investment of this project is 70.7 billion yuan. The main construction content is the annual production of 500,000 tons of synthetic ammonia, 800,000 tons of urea, 60,000 tons of melamine and new material production equipment and supporting related public projects. To date, a total investment of 1.206 billion yuan has been completed. The project uses mature and reliable technologies such as clean coal gasification, ammonia synthesis, low-temperature methanol washing, sulfur recovery, isothermal transformation, liquid nitrogen washing and other mature and reliable technologies to produce synthetic ammonia, and then use synthetic ammonia as raw materials to produce urea, melamine and other products. After the Shaanxi Coal Longhua Mining Coal Classification Clean and Efficient Comprehensive Utilization Project is completed, the coal washed from the coal washing plant will be sent to the gasifier for the production of synthetic ammonia. The remaining methane and other combustible gases after processing the synthetic ammonia, as well as coal slime and gangue, will be sent to the power plant for fuel power generation. The electricity, heat and steam produced by the power plant will be sent to coal mines and chemical plants for use; synthetic helium will finally produce urea. Forming a complete "from black to white" industrial chain from coal to synthetic ammonia to urea products. Shaanxi Coal Longhua Mining focuses on the goal of "carbon peaking and carbon neutrality" and optimizes and upgrades the technical route and product plan for the originally proposed coal graded, graded, clean, efficient and comprehensive utilization project. After the energy-saving review of the project was approved by the Shaanxi Provincial Development and Reform Commission at the end of April, the project construction was fully resumed. At present, the project procedures are all in place, and the bidding process for the EPC general contracting of 8 bidding sections has been completed.
