HuaFei Engineering Undertakes Lihuayi Weiyuan Lithium Battery Electrolyte Solvent Plant Process Optimization and Quality Improvement Renovation Project Safety Facility Design Review Successfully Passed
Recently, the safety facility design review meeting for the process optimization and quality improvement renovation project of the lithium battery electrolyte solvent plant of Lihuayi Weiyuan Chemical Co., Ltd. was successfully held.
The Lijin County Emergency Management Bureau organized safety experts to conduct a technical review of the safety facility design specification. Relevant persons in charge from the project construction unit, Lihuayi Weiyuan Chemical Co., Ltd., and the design unit, Hebei Huafei Engineering Design Co., Ltd. (hereinafter referred to as "HuaFei Engineering"), attended the meeting together.
This project does not change the existing product capacity of the plant. Through the renovation of the existing dimethyl carbonate unit, ethyl methyl carbonate unit, tank farm, and loading/unloading facilities, and by adding equipment and facilities such as sodium methoxide methanol solution as a co-catalyst, hydrolysis carbonization, dimethyl carbonate melt crystallization, ethanol dehydration, and carbonate solvent separation and recovery, the production process is optimized, and necessary utilities and auxiliary facilities are provided to achieve quality improvement and upgrading of the target products.

At the meeting, the lead author of the safety facility design specification of HuaFei Engineering gave a detailed report on the project's general layout, core technical solutions, and the situation regarding the "two key points and one major" (key regulated hazardous chemical processes, key regulated hazardous chemicals, and major hazard installations). Safety experts conducted in-depth reviews from multiple dimensions, including process interlock control, automatic fire alarm systems, blast resistance safety assessment, and compliance of reused facilities. The lead author and the chief designers of various disciplines from HuaFei Engineering provided targeted and detailed answers to each question. After in-depth discussion and rigorous deliberation, the expert group unanimously agreed to approve the safety facility design of the project. Next, the construction unit and the design unit will carefully rectify the issues in accordance with the opinions and suggestions put forward by the expert group and file them for record according to procedures. (This project obtained the safety facility design review opinion letter for hazardous chemical construction projects on September 29, 2026.)
