Power supply to the gasification substation of Yushen Energy Chemicals’ 500,000 tons/year coal-based ethanol project operated by Yan’an Petroleum was successfully established. Author/Source: Huahua Network – Coal Chemical Industry. Date: May 1, 2022. Clicks: 12. On April 28, the 10kV primary power supply to the gasification substation of this project was successfully established. The gasification substation of this project consists mainly of 4 dry-type transformers with a capacity of 2000 kVA, 26 10 kV switchgear cabinets, and 103 low-voltage switchgear cabinets, and is responsible for supplying power to facilities such as the gasification unit, ash treatment systems, and filter rooms. The Mobile Department, the Operation and Maintenance Workshop of Yushen Nenghua Company, along with all the participating units, maintained a high standard of quality and strict requirements throughout the process, following the pre-established power reception plan meticulously to ensure safety and reliability in the operations. After 3 line impulse tests as well as one or two phase comparison tests, successful 10kV power reception at the gasification substation was achieved. The successful power supply to this gasification substation lays the foundation for subsequent individual unit tests and the commissioning of the equipment, while also accelerating the progress of the ethanol project. 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 completed 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 awarded 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-class aerospace furnaces.
