Clicks: 44. On May 19, the **Ministry of Environmental Protection issued a statement announcing that it had officially accepted the environmental impact assessment documents for Huaxing New Energy Co., Ltd.’s project to produce 4 billion Nm3 of natural gas per year from coal. It will be made public, with the publicity period running from May 19, 2017, to June 2, 2017 (10 working days). On January 20, 2014, the 4 billion Nm3/year coal-to-natural gas project of Inner Mongolia Huaxing New Energy Co., Ltd. received the reply from the General Office of the **Development and Reform Commission titled \"Reply on the Preliminary Work for the Coal-to-Natural Gas Pilot Project of Inner Mongolia Huaxing New Energy Co., Ltd.\" (Document No. Fa Gai Ban Neng Yuan 188), which approved the initiation of the preliminary work for this project. To date, the project developer has obtained a series of relevant approvals and agreement documents regarding land use, energy, infrastructure utilization, and pollutant emissions. The project undertakes the task of demonstrating the industrial application of domestic proprietary 5-meter fixed-bed coal gasification under pressure technology; it utilizes advanced process technologies and equipment to achieve the localization of key equipment such as large-scale air separation units, refrigeration compressors, and methanation cycle gas compressors. The project uses water from the Yellow River as its source of industrial water, and the water resources assessment report has been approved by the Yellow River Water Resources Commission (Document No. Huangshui Tiao 141). Inner Mongolia Huaxing New Energy Co., Ltd.’s 4 billion Nm3/year coal-to-natural gas project: Owner of the project: Inner Mongolia Huaxing New Energy Co., Ltd.; Nature of the construction: New construction; Scale of construction: Production capacity of 4 billion Nm3/year of coal-to-natural gas. Synthetic natural gas is produced using technologies such as fixed-bed pressurized gasification, sulfur-tolerant shift reaction, low-temperature methanol washing for purification, and nickel-based catalysts for methane synthesis. The main by-products include tar, middle oil, crude phenol, naphtha, sulfur, sulfuric acid, and liquid ammonia. A heating station is constructed as part of the infrastructure; the steam generated by the waste heat boiler used in methane synthesis is used to drive 2×100MW extraction-type steam turbine units ； Low-pressure steam generated by the low-pressure waste heat boiler is used to drive 2×10MW condensing steam turbine units ； The boiler room is equipped with 8×480t/h pulverized coal steam boilers and 3×25MW back-pressure steam turbine units, resulting in a total power generation capacity of 227,924 KW for the entire plant. It is also accompanied by storage and transportation engineering, utility engineering, auxiliary engineering, and environmental protection engineering, among others. Construction location: The Shanghai Miao Energy and Chemical Industry Base is located in the central-southern part of the Inner Mongolia Autonomous Region, on the northwest edge of the Ordos Basin in the Hetao area of the Yellow River. It lies at the border between the Inner Mongolia Autonomous Region and the Ningxia Hui Autonomous Region, and is administratively under the jurisdiction of Shanghai Miao Town in Eket Quan Banner. The project covers an area of 3,451,330 square meters, with geographical coordinates ranging from 106°31′20″ to 106°57′20″ east longitude, and from 38°09′40″ to 38°46′20″ north latitude. Total project investment: 2,443,455.68 million yuan. Project composition: The project uses coal as raw material to produce natural gas through processes such as gasification, shift cooling, low-temperature methanol washing, and methanation. The project components include the main structure, auxiliary works, utility systems, storage and transportation facilities, environmental protection measures, and supporting projects. http://img.yf116.cn/image/img/20170522/911103307086.jpg Auxiliary facilities mainly include air separation units, compression and refrigeration systems, flare systems, fire stations, and analysis laboratories ； Public utilities mainly include chemical water treatment systems, circulating water systems, and drainage systems, etc ； Storage and transportation engineering mainly includes systems for storing raw coal and fuel coal, storing ash and slag, as well as storage tanks for other liquid raw materials, auxiliary materials, and by-products ； Environmental protection engineering includes the treatment and disposal of wastewater, waste gas, and solid waste ； The supporting projects include off-site water supply systems and pipelines, off-site power transmission lines, natural gas transmission pipelines, slag dumps, hazardous waste disposal sites (these supporting projects are not within the scope of evaluation for this project), etc. Product plan: The output of synthetic natural gas from the main product is 50.66×104 Nm3/h, which equals 1215.8×104 Nm3/day and 40.527×108 Nm3/year. By-products include tar, middle oil, crude phenol, naphtha, sulfur, and sulfuric acid, etc. Process route and production plan: http://img.yf116.cn/image/img/20170522/9121033130100.jpg http://img.yf116.cn/image/img/20170522/913173319722.jpg Project demonstration tasks: The specific tasks related to process demonstration include the industrial application of domestic fixed-bed coal gasification technology under pressure; the gasification pressure is above 4.0 megapascals, and the diameter of the gasification furnace is increased to 5 meters ； Second is the localization of key equipment such as large-scale air separation units, refrigeration compressors, and methanation cycle gas compressors. It also undertakes the environmental protection demonstration task of \"membrane filtration for oil and dust removal technology\". It undertakes environmental protection demonstration tasks in areas such as the efficient utilization of coal based on its different quality levels, the combined use of resources and energy, and pollution control technologies (such as wastewater treatment techniques, wastewater disposal methods, and utilization and disposal strategies for crystalline salts).
