Shanxi Yixin Energy Technology's 3 million tons/year low-rank coal quality comprehensive utilization project environmental impact assessment was approved author/source: Chemical Network Coal Chemical Industry Date: 2023-03-31 Click rate: 170 Recently, the environmental impact assessment of Shanxi Yixin Energy Technology Co., Ltd.’s 3 million tons/year low-rank coal quality-separated comprehensive utilization project was approved by the Shanxi Provincial Department of Ecology and Environment. The project is located in the Yuanping Economic and Technological Development Zone of Xinzhou City (the starting area of the Yuanping Circular Economy Industrial Park). The project has an annual processing capacity of 3 million tons of low-rank coal. It adopts domestic advanced low-rank coal quality utilization technology to pyrolyze low-rank coal. The Fischer-Tropsch synthesis project uses coke oven gas as raw material, produces cobalt-based Fischer-Tropsch products through purification, conversion, and Fischer-Tropsch synthesis, and develops a new way to utilize coke oven gas. Shanxi Xinshi Energy Technology Co., Ltd. was established in 2011 and is jointly invested by Shanxi Jinlong Energy Investment Co., Ltd. and Shanxi Fengneng Investment Co., Ltd. Shanxi Yixin Energy Technology Co., Ltd. is a wholly-owned subsidiary of Shanxi Xinshi Energy Technology Co., Ltd. and was established in May 2020. Shanxi Yixin Energy Technology Co., Ltd.'s first-phase 2 million tons/year metallurgical coke and coal chemical project and the second-phase 3 million tons/year low-rank coal quality comprehensive utilization project cover a total area of 2,670 acres. The main products of the 3 million tons/year low-rank coal quality comprehensive utilization project include: Upgraded coal is 1.8 million tons/year, tar is 270,000 tons/year, and coal gas is 300 million Nm3/year. The project has an annual processing capacity of 3 million tons of low-rank coal. It adopts the current advanced low-rank coal quality utilization technology to achieve comprehensive utilization of coal under mild conditions. The pyrolysis products are high-quality upgraded coal, low-temperature coal tar with high hydrogen-to-carbon ratio, and low-temperature pyrolysis gas with high calorific value. Clean fuels such as gasoline, diesel, and CNG (LNG) are produced through deep processing of coal tar and pyrolysis gas. The total investment of the 3 million tons/year low-rank coal quality comprehensive utilization project is 1.36 billion yuan, of which 44.46 million yuan is invested in environmental protection. The main construction content includes pyrolysis and quality improvement and gas purification, supporting construction of phenol ammonia recovery, desulfurization waste liquid salt extraction and other projects, as well as corresponding auxiliary projects, storage and transportation projects, public works and environmental protection projects. After purification, part of the gas is reused in the hot stove, and the remaining part is sent to * * Shanxi Aluminum Co., Ltd. of China Electric Investment Group has an annual output of 2.6 million tons of alumina project as a clean fuel.
