Recently, the wireless cluster system for Yanchang Petroleum Yushen Energy’s 500,000 tons per year coal-based ethanol production project was successfully installed and tested, and it is now fully in use. It is reported that the Yushen ethanol project is equipped with one digital trunking system based on a single base station. This system enables seamless two-way communication and recording throughout the entire area, as well as smooth integration between walkie-talkies and dispatch phones, mobile phones, and public address systems. During the commissioning phase, the Mobile Equipment Department and the Operations and Maintenance Workshop of Yushen Energy Chemical Company, together with the relevant contractors involved in the project, closely monitored changes in various indicators, refined the commissioning procedures, and successfully completed the commissioning tasks. The successful deployment of this wireless cluster system provides a solid foundation for the commissioning and operation of subsequent devices, and it also contributes to the timely completion and testing 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 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 (devices such as coal unloading and storage facilities, gasification units, shift reactors, 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 construction 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-class aerospace furnaces.
