According to Guizhou Yufu Energy Development Co., Ltd., the environmental impact assessment for the 2 million tons per year coal-to-clean-fuel project in Bijie, Guizhou, has been completed. To enhance the transparency of environmental impact assessment information, the full report on the environmental impacts of this project is now available for public download (it can be obtained by visiting the company’s official website). The next step is to submit it to the **Ministry of Environmental Protection for approval; the project is scheduled to begin construction in 2017 and be completed by 2018. **The \"13th Five-Year Plan for Demonstrating the Upgrading of Deep Coal Processing\" issued by the Energy Bureau stipulates that by 2020, China’s coal-to-oil production capacity should be 13 million tons per year. Among them, the 2 million tons per year coal-based clean fuel project in Bijie, Guizhou, has been included as a new demonstration project under the 13th Five-Year Plan; the demonstration tasks involve the clean and efficient comprehensive utilization of high-sulfur coal, as well as the production of gasoline through indirect coal liquefaction. The 2 million tons per year coal-based clean fuel project in Bijie, Guizhou, is one of the key strategic projects under the energy development plan for the 13th Five-Year Plan period, aimed at achieving clean and efficient utilization of coal. It is also one of the key projects for deep processing of coal to produce oil during that period, as well as one of the four new projects planned for this purpose. Furthermore, it is the only coal-to-oil demonstration project in the southern region during the 13th Five-Year Plan period. Guizhou Yufu Energy Development Co., Ltd. was established with the approval of the ** authorities in Chongqing, as well as the approval of the Chongqing State-owned Assets Supervision and Administration Commission, and it is led by Chongqing Yufu Asset Management Group Co., Ltd. The business scope includes coal chemical industry, coal-to-oil related industries, the sale of mineral products, and non-financial investments. The company was established in August 2008, with a registered capital of 500 million RMB. Basic Information of the Project (1) Project Name: 2 million tons/year coal-based clean fuel project in Bijie, Guizhou (2) Project Owner: Guizhou Yufu Energy Development Co., Ltd. (3) Nature of Construction: New construction (4) Location of Construction: Shabao Township, Nayong County, Bijie City, Guizhou Province (5) Land Area: The project requires 372.85 hm2 of land for construction, of which 369.85 hm2 is dedicated to the project itself. The wastewater treatment plant for the facility is located within the designated area and covers approximately 3 hm2 (6) Total Scale of the Project: The production capacity for coal-based clean fuel is 2 million tons per year; the nominal capacity is also 2 million tons per year. In reality, the actual output is 2.2696 million tons per year, with 1.3416 million tons per year being gasoline, 700,200 tons per year diesel, 111,500 tons per year LPG, and 116,200 tons per year LNG. By-products include solid sulfur, sulfuric acid, light alcohols, and heavy alcohols. The project also includes related utility systems, auxiliary facilities, and environmental protection measures (7) Operating Hours: 8,000 hours per year (8) Project Investment: The total investment in the project amounts to 3,550,234 million yuan, of which 3,575,022.5 million yuan is allocated to environmental protection facilities (excluding costs related to project evaluation). Environmental protection investments account for approximately 10.07% of the total construction cost (9) Labor Force and Working Hours: The total number of employees required is 1,492, with a working schedule of four shifts per day (3 shifts running simultaneously) (10) Construction Timeline: Construction is scheduled to begin in December 2017, with completion expected by March 2021. Project Composition: The construction scope of the project includes the main structure, storage and transportation facilities, utility systems, auxiliary facilities, environmental protection measures, and supporting infrastructure. The main process units of the project are divided into 8 production units, namely the air separation unit, gasification unit, purification unit, sulfur recovery unit, oil synthesis unit, oil processing unit, gasoline production unit, and exhaust gas treatment unit. In addition, there are various major utility systems, auxiliary systems, and environmental protection facilities, including thermal power generation units, water supply and drainage systems, air compression stations, flare systems, power supply and distribution stations, telecommunications facilities, ventilation systems, facilities for storing and transporting products and materials, instrumentation and process automation control systems, warehouses, laboratories, office buildings, sewage treatment plants, intermediate slag storage areas, and hazardous waste temporary storage facilities. http://img.yf116.cn/image/img/20170621/968327681.jpg Overall Process Flow: The project utilizes coal as a raw material and indirect liquefaction technology to produce liquid fuel products. This technological approach combines elements of coal chemistry with those of petroleum chemistry; it can be divided into two stages – the upstream stage, which involves the production of syngas, and the downstream stage, which involves the synthesis and processing of oil products. (1) Upstream syngas production: Upstream syngas production primarily involves converting coal into crude syngas using coal gasification units. The crude syngas is then purified, and its H2/CO ratio is adjusted to meet the requirements of the Fischer-Tropsch synthesis in the downstream stage. The overall process flow in the upstream stage depends on the gasification technology employed; different gasification technologies result in different overall process flows. After evaluating fixed-bed, fluidized-bed, and gas-flow-bed gasification technologies, the aerospace furnace gasification technology using a gas-flow bed is recommended. The overall process flow for the production of synthesis gas upstream is basically determined as coal gasification → carbon monoxide shift to adjust the hydrogen-to-carbon ratio → removal of acidic gases → obtaining qualified synthesis gas for use in downstream units. Carbon monoxide conversion employs an endothermal sulfur-resistant shift process, while acidic gas removal uses a low-temperature methanol washing process. (2) Downstream oil synthesis and processing: In the downstream phase of this project, the oil synthesis and processing technologies developed independently by Zhongke Synthetic Oil Technology Co., Ltd. are utilized, with the product portfolio focusing on the production of gasoline and diesel. Based on the production process and product scheme, the overall process flow in the downstream stage is determined as upstream syngas → oil synthesis → oil processing → gasoline processing → final product. In summary, the main process flow of the project is as follows: raw coal → coal gasification → carbon monoxide conversion → low-temperature methanol washing → oil synthesis → oil processing → gasoline processing → products
