Guizhou Energy Shuicheng's 2 million tons/year circular economy comprehensive utilization coal coking project is a combination of the Xinsheng coal chemical project (including the power workshop (2x50MW) of Liupanshui Yingshan Coal and Electrochemical Integrated Base and the first phase of the Liupanshui Yingshan Coal and Electrochemical Integrated Base methanol and dimethyl ether chemical project ) Asset revitalization, Guizhou Energy Shuicheng Coal, Electricity and Chemical Integration Co., Ltd. plans to build Guizhou Energy Shuicheng 2 million tons/year circular economy comprehensive utilization coal coking project at the original site of the Xinsheng Dou Chemical Project. The construction content is an annual output of 2 million tons of coking, 186 million m3 SNG projects and supporting facilities. The construction contents of Xinsheng Coal Chemical Project include 200,000 ta methanol, 150,000 ta dimethyl ether and 2x50MW power plant. In 2007, it obtained the approval of the former Guizhou Provincial Environmental Protection Bureau (Guizhou Environmental Protection Letter [200745] No. 2, Qianhuanhan (2007) No. 453), the main project and supporting environmental pollution prevention and control facilities have been basically completed, and trial production was carried out in 2014. After passing the environmental protection acceptance in 2016, production has been suspended until now. Guizhou Energy Shuicheng's 2 million tons/year circular economy comprehensive utilization coal coking project is located in the coal-based industrial area of Guizhou Shuicheng Economic Development Zone. Together with the Guizhou Energy Shuicheng 2×660,000 kilowatt coal-fired power generation project to be built to the south of the project, it will create a "coal-coke-chemical-electricity" circular economy industrial chain. The total area of the project is approximately 6,504 acres (43.36ha), with a total investment of 4,162,611,600 yuan. It has an annual output of 2 million tons of dry coke, all dry quenching, and is equipped with a dry quenching coke waste heat power generation device. Including coal preparation, coking, dry quenching, coke processing, and gas purification systems. The remaining coke oven gas is used to produce natural gas (SNG), with an annual output of 186 million m3 SNG, and the by-product hydrogen-rich gas is burned to generate electricity. Guizhou Energy Shuicheng 2 million tons/year circular economy comprehensive utilization coal coking project Construction unit: Guizhou Energy Shuicheng Coal, Electricity and Chemical Integration Co., Ltd. Construction nature: New Construction location: Shihe Community, Yingshan Street, Shuicheng District, Liupanshui City Total investment: 4,162,611,600 yuan Area: 650.4 acres (43.36ha) The construction scale has an annual output of 2 million tons of dry coke, SNG production from coke oven gas of 186 million m3/a, and supporting gas purification (chemical product recovery), dry quenching coke waste heat and hydrogen-rich power generation equipment. Project composition: The project plans to build a set of 2×70 hole 6.78m tamping coke oven and 3×130t/h dry coke quenching device, all dry quenching. Including coal preparation, coking, dry quenching, coke processing, and gas purification systems. Construct a natural gas (SNG) device from residual coke oven gas, which will also be equipped with dry quenching waste heat and hydrogen-rich power generation devices. The project components include the construction of a set of 2×70 hole 6.78m tamping coke oven and 3×130t/h dry coke quenching device, with full dry quenching. Including coal preparation, coking, dry quenching, coke processing, and gas purification systems. Constructing a natural gas (SNG) device from residual coke oven gas, supporting dry quenching coke waste heat and hydrogen-rich power generation device
