Multiple images! Review of the construction progress of Xinjiang Xinji Energy Chemical’s 1.5 million-ton compound fertilizer and 300,000-ton diesel engine exhaust treatment agent production projects

The Xinjiang Xinji Energy Circular Economy Project utilizes technologies such as Jinhua furnace water-coal slurry gasification (waste boiler process), shift reaction, low-temperature methanol washing, liquid nitrogen washing, sulfur recovery, ammonia refrigeration, 15MPa ammonia synthesis, CO2 stripping for urea production, European high-pressure process for melamine production, high-tower compound fertilizer production, and fluidized-bed compound fertilizer production. The project has an annual production capacity of 1.5 million tons of new type water-soluble compound fertilizers, 300,000 tons of diesel engine exhaust treatment agents, and 120,000 tons of melamine. The Xinjiang Xinji Energy Circular Economy Joint Chemical Project is located in the Shuangfeng Circular Economy Industrial Park in Tiemenguan City, Second Division of the Xinjiang Production and Construction Corps, and has been included as a key construction project in the \"14th Five-Year Plan\" of the Autonomous Region’s State-owned Assets Supervision Commission. Upon completion, the project will be able to produce 1.5 million tons per year of new types of water-soluble compound fertilizers, 300,000 tons per year of diesel engine exhaust treatment agents, and 120,000 tons per year of melamine, thus becoming Xinjiang’s largest nitrogen fertilizer production base. Image: The total investment in the Xinjiang Xinji Energy Circular Economy Joint Chemical Project is 5.86 billion yuan. Backed by the Ministry of Agriculture and Rural Affairs’ restrictions on the use of agricultural fertilizers and its push to increase the use of water-soluble compound fertilizers, as well as the large market for vehicle exhaust treatments, this project takes full advantage of the coal resources produced by Jinchuan Group in Tiemenguan City, Second Division, along with favorable development policies. It utilizes molten urea produced by upstream urea production facilities to manufacture new types of water-soluble compound fertilizers, diesel engine exhaust treatment agents, and melamine.

According to news from October 29, 2024, the No. 3 boiler of the thermal power unit in the circular economy integrated chemical project undertaken by China Tianchen Engineering Co., Ltd. for Xinjiang Xinji Energy and Chemical Co., Ltd. – a project involving the production of 1.5 million tons per year of new type water-soluble compound fertilizers along with 300,000 tons per year of diesel engine exhaust treatment agents – was successfully ignited for the first time. The successful commissioning of Boiler No. 3 marked the beginning of the steam pipeline purging process, and it was a crucial step in advancing the entire project. It not only indicated the stable operation of the thermal power plant but also laid a solid foundation for the full operation of the Xinjiang Xinji Energy project. The Xinjiang Xinji Energy Circular Economy Project utilizes technologies such as Jinhua furnace water-coal slurry gasification (waste boiler process), shift reaction, low-temperature methanol washing, liquid nitrogen washing, sulfur recovery, ammonia refrigeration, 15MPa ammonia synthesis, CO2 stripping for urea production, European high-pressure process for melamine production, high-tower compound fertilizer production, and fluidized-bed compound fertilizer production. The project has an annual production capacity of 1.5 million tons of new type water-soluble compound fertilizers, 300,000 tons of diesel engine exhaust treatment agents, and 120,000 tons of melamine.

On October 23, 2024, the first trial operation of Mill No. 1 and Mill No. 3 for slurry preparation at Unit 610 of the gasification plant in the circular economy integrated chemical project of Xinjiang Xinji Energy Chemical Co., Ltd. – a project that involves the production of 1.5 million tons per year of new type water-soluble compound fertilizers along with 300,000 tons per year of diesel engine exhaust treatment agents – was successfully completed. This project was undertaken by the Northwest Branch of China National Chemical Engineering 16th Construction Co., Ltd. The total weight of a single rod mill is 331 tons; the diameter of its cylinder is 4 meters, and its length is 6 meters. The equipment is driven by a 1,400-kilowatt main motor, and is equipped with auxiliary devices such as reducers, slow-speed transmission units, gears, and dry oil injection systems.

On October 12, 2024, coal was fed into Boiler No. 3 of the circular economy integrated chemical project at Xinjiang Xinhui Energy and Chemical Co., Ltd., which involves the production of 1.5 million tons per year of new type water-soluble compound fertilizers along with 300,000 tons per year of diesel engine exhaust treatment agents. Steam reached the designed pressure for blowing, enabling a successful one-time ignition and operation with coal feeding. The successful ignition and coal feeding of Boiler No. 3 provide a solid foundation for the subsequent steam purging of the entire plant, the commissioning of the large-scale units, and the supply of steam to various facilities. It represents another significant milestone toward the company’s goal of achieving operational capacity by the end of the year. According to reports from October, the Xinjiang Xinhui Energy project has reached various milestone stages, including the commissioning of the desalinated water station and the production of qualified desalinated water, as well as the installation of the condensers in the urea synthesis unit.
