Progress on the Construction of Yanchang Petroleum Yushen Energy Chemicals’ 500,000 tons/year coal-based ethanol project / Author/Source: Huahua Network Coal Chemicals / Date: February 24, 2022 / Clicks: 10. On February 21, Yanchang Petroleum Yushen Energy Chemicals organized relevant technical personnel from the EPC contractor, supervision unit, construction company, and equipment manufacturers to hold a meeting in the on-site conference room to discuss the progress of installing the methanol degreasing tower (T-404) for the ethanol production facility. The successful holding of this meeting marked the official start of the installation work for the internal components of this tower. It is reported that the methanol deesterification tower (T-404) is one of the key equipment in the ethanol production facility. This tower has a diameter of 6.7 m and a height of 99.16 m; its internal volume is approximately 2,115.4 m3. The material used for construction is 304 steel. There are a total of 10 sections of structured packing, with each section having a height of 6 m, and the packing used is of type 500Y plate corrugated packing. 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 the coal-to-ethanol technology developed jointly by Yanchang Petroleum and Dalian Institute of Chemical Physics, which holds independent intellectual property rights. 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. (BPPEC) has been entrusted with the EPC general contracting work worth 3.78 billion yuan. This includes utility facilities and plant-wide system engineering, as well as process units and water treatment systems. The company is also responsible for overall project management services. 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-class aerospace furnaces.
