As of August 28, the vanadium acid production catalyst developed through independent research by the R&D institute of Nanhua Company has been operating continuously and stably for three months in Guangdong Hongrui Energy Technology Co., Ltd.’s 300,000 tons per year project for the comprehensive utilization of resources in wet acid production. Data show that the key performance indicators of this catalyst are on par with those of imported catalysts, breaking the technical monopoly held by imported catalysts in ultra-large-scale wet acid production plants and laying a solid foundation for the subsequent promotion of domestic alternatives. On May 28, the project was successfully commissioned, with an annual production capacity of 330,000 tons of sulfuric acid. It is currently the largest wet-process sulfuric acid production facility in operation worldwide, and its core reaction zone utilizes vanadium catalysts for wet-process sulfuric acid production that were independently developed by the R&D institute of Nanhua Company. During the commissioning of the plant, the technical team from Nanhua Company provided technical support throughout the process, effectively resolving issues such as abnormal increases in the temperature of the catalyst bed, thereby ensuring the stable operation of the catalyst and the smooth commissioning of the plant. The R&D institute of Nanhua Company continues to drive technological innovation. The vanadium acid catalyst developed using the wet process features advantages such as a simple production process, high sulfur recovery rate, high energy efficiency, and no wastewater generation. It has been successfully applied in more than 30 manufacturers both domestically and internationally, and has been included in Sinopec’s list of internal premium products. Next, the hospital will carry out the replacement of the catalysts in the entire set of sulfur dioxide converters, in order to promote the wider use of domestically produced vanadium catalysts for acid production via the wet process.
