The Ministry of Science and Technology of Qinghai Province organized relevant experts recently to carry out the acceptance and results appraisal of the project “Study on the key technology for the production of sodium dichromate by electrosynthesis†undertaken jointly by the Qinghai Salt Lake Research Institute of the Chinese Academy of Sciences and Qinghai Chromium Salt Hi-tech Co., Ltd. The review team highly praised the innovation of this technology, which indicates that the key technology for the production of sodium dichromate by the electrosynthesis of the Qinghai Salt Lake Institute has achieved important breakthroughs. The expert group believes that this project uses sodium chromate solution as raw material and adopts two-stage electrolytic electrolysis to solve the key technical problem of electrosynthetic production of sodium dichromate, forming a complete clean production process with short process flow and products. With high purity and low pollution emission, it provides a technical demonstration for chromium salt chemical industry and the technical achievements have reached the international advanced level. Chromium salt products are an indispensable chemical raw material for the development of the national economy. However, due to its own strong oxidizing properties, it can destroy and corrode organisms. The discharge of chromium residues, waste liquids, and waste gas during the production of traditional chromium salts is large. The chromium salt industry has long been ranked as the first of heavy pollution industries, and it is urgent to improve the production process. industrial restructuring. A team composed of researchers from Qinghai Salt Lake Research Institute, Dong Yaping and Dr. Feng Haitao, used electrochemical synthesis methods to synthesize sodium dichromate by electrolysis, and built the first domestic electrosynthetic sodium dichromate pilot plant, completing 500 Tons of sodium dichromate pilot mission. It is reported that this technology has been listed by the Ministry of Industry and Information Technology as one of the four major processes for promotion and application to the national chromium industry. For the chromium salt production enterprises adopting the technology in 2012 and 2013, the state will provide financial incentives. After 2013, the old process of chromium salt companies will be completely eliminated. The leaders and experts of the Ministry of Environmental Protection, the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology of Qinghai Province, and the Economic Commission of Qinghai Province believe that this technological breakthrough is of great significance to the realization of cleaner production in the chromium salt production industry and can greatly improve the production of chromium salts. The current situation of serious pollution is expected to bring about major changes in the chromium salt production industry. About Silicone phone holder:
