Erection of the largest steel grid structure for Yushen Energy’s 500,000 tons/year coal-based ethanol project completed Author/Source: Beijing Petrochemical Engineering Co., Ltd. Date: May 7, 2022 Clicks: 15 On May 5, the grid structure for the circular coal storage area of Yushen Energy’s 500,000 tons/year coal-based ethanol project, which was constructed under EPC contract by Beijing Petrochemical Engineering Co., Ltd., was successfully erected. The circular coal storage yard is a fully enclosed hemispherical structure with a construction area of approximately 5,800 square meters. It can store 40,000 tons of coal, meeting the entire plant’s coal storage needs, and it is the largest steel mesh structure building in the plant. The single span of this coal yard is 80 meters, and the height of its grid structure is approximately 60 meters; as a result, construction is challenging and high safety standards are required. After 29 days, this lifting task was completed with high quality, ensuring the timely commissioning of the coal yard. The Yushen 500,000 tons per year coal-based ethanol project is currently the largest project in the industrialization of coal-based ethanol technology. With a total investment of 6.98 billion yuan, it is located in the South Area of Qingshui Industrial Park within the Yushen Industrial Park in Yulin City, Shaanxi Province. The project covers an area of 1,365 mu, and it utilizes coal-to-ethanol technology that was jointly developed by Yanchang Petroleum and Dalian Institute of Chemical Physics and for which independent intellectual property rights exist. The project is scheduled to be fully handed over on May 30, 2022. The construction scope includes a methanol complex (units such as coal unloading and storage facilities, gasification units, shift conversion units, purification units, gas separation units, methanol production units, and sulfur treatment units), an ethanol plant (units including dimethyl ether production, carbonylation processes, hydrogenation units, separation systems, compression equipment, heating furnaces, and refrigeration stations), as well as new constructions for utility systems and auxiliary facilities; the design capacity is 1.22 million tons of coal to be converted per year. Beijing Petrochemical Engineering Co., Ltd. (Beiyou Engineering) has been assigned a total EPc contract value of 3.78 billion yuan, covering auxiliary facilities and plant-wide system projects, as well as process units and water treatment systems; it is also responsible for providing overall project management services for this project. As the EPC general contractor for the gasification unit of this project, Aerospace Engineering Company signed a general contract with Yushen Energy Chemical Company worth 590 million yuan; the project utilizes two 2,000-ton capacity aerospace furnaces.
