【Ten Years of Rapid Development in Chemical Equipment】From 2026 to 2026: China’s independently developed process technologies come into use with the launch of the electronic-grade isopropanol new material project at Jinzhou Petrochemical

In today’s era of rapid advancement in the electronics industry toward higher-end products, precision manufacturing in fields such as semiconductors, photovoltaics, and liquid crystal panels relies on a type of \"ultra-pure cleaning agent\"—electronic-grade isopropyl alcohol (IPA). Among them, Grade G5 serves as the core standard for high-end electronic solvents, imposing extremely strict requirements on purity and impurity control. For a long time, over 80% of the high-purity isopropyl alcohol used in the domestic market has had to be imported, with the core technologies and production capacity controlled by foreign companies. Today, China National Petroleum Corporation’s Jinzhou Petrochemical Plant, in collaboration with Xiamen Luhui Chemical, has successfully installed the first G5 electronic-grade isopropanol production facility within CNPC’s network, breaking through industry constraints. Let’s join CNPC to explore the journey that led to the creation of this \"cornerstone of the electronics industry\". As the first G5 electronic-grade isopropanol production facility within CNPC’s system, this project at Jinzhou Petrochemical carries the important mission of breaking through the technical barriers associated with high-end electronic solvents and filling a gap in the company’s product portfolio. Unlike traditional industrial-grade isopropanol, G5 electronic-grade isopropanol is characterized by its \"ultra-purity and absence of impurities.\" It has strict requirements regarding the removal of metal ions, with these levels needing to be kept below 10 ppt. It can be widely used in key processes such as semiconductor wafer cleaning, photoresist stripping, and surface treatment of photovoltaic cells, and it is an essential basic material for the electronics industry’s transition to more advanced manufacturing processes. The successful implementation of this high-end product is made possible by the full support provided by Xiamen Luhui Chemicals, the provider of the process package. Established in 2009, Xiamen Luhui Chemical has been working in the field of chemical technology services for over a decade, boasting extensive expertise in engineering design and project management. As the provider of the process package for this project, Lu Hui Chemical took full lead in implementing the project’s core technologies, striving for excellence at every stage – from the preparation of feasibility study reports and the optimization of process plans, to detailed design and the final determination of technical parameters ； At the same time, it was involved throughout the entire project development process in coordinating efforts, mobilizing various resources to address technical challenges that arose during construction, and ensuring strict control over every detail of the production process. This approach helped to guarantee that the final product quality met the G5 standards, thereby laying a solid technical foundation for the smooth progress of the project.

From project initiation to the completion of the product, the development of Jinzhou Petrochemical’s G5 electronic-grade isopropanol facility proceeded in an efficient and orderly manner, with clear milestones. The project is built on the land reserved within the existing facility of Jinzhou Petrochemical, with a total investment of 168.25 million yuan and an area of 13,684.4 square meters; no additional land is required, thus enabling efficient utilization of existing resources. In October 2024, the installation process officially entered the mechanical and electrical installation phase, with the construction team overcoming various construction challenges while ensuring strict quality control ； In March 2025, the mechanical commissioning was successfully completed, laying a solid foundation for subsequent operation and commissioning of the facility ； After half a year of debugging and optimization, in September 2025, the facility was successfully brought online and began producing qualified products; it met the required standards from the very first operation, marking CNPC’s breakthrough into the field of high-end electronic solvents. The successful mass production of this G5 electronic-grade isopropyl alcohol holds far greater significance than merely the introduction of a single product. At the corporate level, it fills the gap occupied by CNPC in the field of high-end electronic solvents, enriches the company’s portfolio of high-end chemical products, facilitates the transition from traditional \"heavy chemicals\" to high-end \"fine chemicals\", and further enhances the company’s core competitiveness ； At the industry level, it addresses the issue of China’s reliance on imported high-purity isopropanol, breaks the technical and market monopolies held by foreign companies, helps increase the self-sufficiency rate of electronic-grade isopropanol in China, and alleviates the contradiction of \"structural overcapacity and shortage of high-end products\" in the isopropanol industry ； From an industrial perspective, it provides domestically produced high-end electronic solvents for strategic emerging industries such as semiconductors and photovoltaics in China, reducing the supply chain risks for these industries. It contributes to the independent and sustainable development of China’s electronics industry, while also serving as a model for the traditional refining industry to transform into a more advanced and sophisticated sector. It is worth noting that this project also stands out in terms of environmental sustainability. During operation, waste gas is treated through \"two-stage water washing + activated carbon adsorption\" before being discharged in compliance with standards; wastewater is sent to the company’s existing oil refining wastewater treatment plant for processing, with strict adherence to all environmental protection regulations ； The waste resin generated in the production of ultra-pure water is recovered by the manufacturer, and hazardous waste is stored and transported in accordance with relevant regulations, thereby achieving a win-win situation in terms of economic benefits and environmental protection. With the mass production and supply of this domestically produced G5 electronic-grade isopropanol, it will further disrupt the landscape of the global high-end electronic solvent market, promote the high-quality development of China’s electronic chemicals industry, and provide strong impetus for the advancement of China’s electronics industry to higher levels.
