Progress on the Construction of Yushen Energy Chemical’s 500,000 tons/year coal-based ethanol project by Yan’an Petroleum. Author/Source: Huahua Network – Coal Chemical Industry.

Recently, the single-test for the high-pressure fluidization fan of Boiler No. 1 in the power plant of Yushen Energy Chemical’s 500,000 tons/year coal-based ethanol project was successfully completed. It is reported that the high-pressure fluidized air fan is one of the key components of CFB boilers; its role is to separate the solid materials carried by the flue gas using a cyclone separator, and then return these materials to the furnace through a return device for further combustion. During the testing period, the operators carefully carried out various tasks such as equipment inspection, lubricant application, verification of operating conditions, and powering on the equipment. After two hours of testing, all parameters of the unit were within the standard range, and the three high-pressure fluidization fans passed their individual tests successfully. Thus, the single test of the first power equipment at the power station of the Yushen Ethanol project was successfully completed. The successful individual testing of the three high-pressure fluidization fans for Boiler No. 1 serves as a signal to get started with the commissioning of the first boiler in the power station of the Yushen Ethanol project. In 2022, Yushen Energy & Chemical Company will continue to fulfill its responsibilities and maintain its confidence, making every effort to carry out all tasks properly to ensure the successful completion of the 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 the 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 (devices 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 processes, separation units, compression systems, 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 initiative. 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.
