Recently, the installation of the first section of the electronic-grade stripping column, a key piece of equipment for Jingmen Yuanhan Battery Materials Co., Ltd.’s 200,000 tons per year ethanol production facility (including electronic-grade ethanol), which was under the general contracting of Beijing Petrochemical Engineering Co., Ltd., was successfully completed. This marks the official start of the installation of large-scale equipment for the ethanol production facility, and the project has now entered the phase of equipment installation and process piping. Yin Changbing, General Manager of Jingmen Yuanhan Battery Materials Co., Ltd. and Deputy General Manager of Beiyou Engineering Company, along with the key officials from the supervision and construction units, were present to witness this important lifting operation. As a key equipment for the project, the electronic-grade degassing tower is designed as a packed tower with partitions, and it is primarily used to remove hydrogen, nitrogen, and other light impurities from anhydrous ethanol as well as those generated during ethane reactions. The tower has a diameter of 3.5 meters and a total height of about 102 meters; the total weight of the equipment and internal components is approximately 410 tons. Given the difficulties of transportation and installation, the equipment is prefabricated in three sections at the factory before being transported to the site, where it is installed using a \"segmental lifting + aerial assembly\" method. To ensure safety, the project team adopted a dual-crane lifting solution of 800 tons + 400 tons, and strictly followed procedures such as equipment inspection and safety briefings. This project involves a total of 26 large-scale pieces of equipment, with a combined weight of around 3,200 tons. These include a carbonyl reactor that weighs up to 580 tons per unit, as well as 4 towers with heights ranging from 90 to 116 meters. Once all the equipment arrives at the site, the process of installing necessary components on them is carried out on the ground first. Since its inception, the project team has always adhered to the construction philosophy of \"safety first, quality foremost, and environmental protection as a priority.\" By optimizing all aspects of the design, procurement, and construction processes and establishing a multi-party coordination mechanism, they ensure the efficient progress of the project. As an important part of the Yuanhan dimethyl carbonate-based chemical products project in Jingmen, Hubei, once completed, the project will have an annual production capacity of 200,000 tons of electronic-grade ethanol. This includes a unit for refining electronic-grade ethanol with an output of 100,000 tons per year; the ethanol produced has a purity of 99.99% and a water content of less than 200 ppm, making it suitable as a high-quality raw material for electrolytes. Currently, the project team is making every effort to advance the subsequent installation work to ensure the project is delivered on schedule and to high quality. The implementation of this project will further enhance the technical level and market competitiveness of China’s ethanol industry, providing strong support for the development of the new energy materials industry chain.
