Ningxia Baofeng Energy Group Co., Ltd.’s 500,000 tons/year coal-to-olefins project. Project type: new construction ； Construction location: Area A of Linhe Comprehensive Industrial Park, Ningdong Energy and Chemical Industry Base, Yinchuan, Ningxia. Construction contents: New air separation unit, gasification unit, shift unit, purification unit, sulfur recovery unit, methanol unit (intermediate product), 500,000 tons/year MTO unit, EVA polymerization unit, propylene polymerization unit, as well as the accompanying auxiliary facilities. The area planned for land acquisition is 252.82 hectares, with 115 hectares allocated for factory facilities. Total project investment: 1,377,000 million yuan; the total investment in environmental protection measures amounts to 979,469.9 thousand yuan, accounting for 7.11% of the total project investment. http://img.yf116.cn/image/img/20200807/953523563251.jpg http://img.yf116.cn/image/img/20200807/957573587777.jpg The project builds on the enterprise’s existing engineering expertise in gasification processes; it utilizes the domestically developed Beijing Aerospace pressurized coal gasification technology, Linde’s technology for low-temperature methanol washing, and the first-generation technology developed by the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences (with a capacity of 500,000 tons per year per system) ； Olefin separation utilizes technology from the American company KBR ； The polypropylene PP plant uses the Lyondellbasell gas-phase process, while the EVA plant employs the Basel high-pressure tubular process ； Sulfur recovery employs a process that includes high-temperature Claus in the furnace, two-stage low-temperature catalytic Claus, hydrogen reduction, and selective oxidation; after combustion of the exhaust gases, they are sent to the power island in the Linhe Industrial Park (where they enter two desulfurization systems in the power station). Baofeng Energy has built the \"Baofeng Energy Circular Economy Industrial Base\" in Areas A and B of the Linhe Comprehensive Industrial Park in the Ningdong Energy and Chemical Industry Base, with the projects that have been put into operation mainly located in Area B. The Baofeng Energy Circular Industry Base is based on coal mining; through coal mining and washing processes, the refined coal is used to produce coke via coking ； Coke oven gas and gasification syngas are recovered and comprehensively utilized to produce methanol; methanol is then used in the MTO process to produce ethylene and propylene, which are further polymerized to yield polyethylene and polypropylene. In-depth processing of high-temperature tar produced as a by-product of coking to manufacture over a dozen products such as phenol, naphthalene, anthracene oil, washing oil, and asphalt ； Crude benzene produced as a by-product of coking is refined through hydrogenation to produce petroleum-grade pure benzene. Since 2005, Ningxia Baofeng Energy has developed a production capacity of \"8.1 million tons of coal, 4 million tons of coke, 1.2 million tons of olefins per year, 600,000 tons of polyethylene, 600,000 tons of polypropylene, and 780,000 tons of fine chemicals.\" The projects that have been built and are in operation in Area B of the Linhe Comprehensive Industrial Park at the Ningdong facility include the 4 million tons per year Maliantai coal mine, a heavy media coal washing project with a capacity of (400+600) million tons per year, Phase I/II coking projects with a capacity of (200+200) million tons per year, a 200,000 tons per year methanol production project using coke oven gas (including Phase I of the power station), a 300,000 tons per year coal tar processing project, a 100,000 tons per year crude benzene hydrogenation refining project, and a project for the comprehensive utilization of coking plant waste gases to produce olefins (including Phase II of the power station). The project for producing 600,000 tons per year of olefins through coke gasification, constructed in Area A of the Linhe Comprehensive Industrial Park in the Ningdong base, successfully completed its trial operation at the end of May 2020.
