On March 24, the Ministry of Industry and Information Technology issued a public announcement document on the "Catalogue of Technologies and Products Encouraged by the Petrochemical and Chemical Industry to Promote and Use" on its official website. The document shows that a total of 32 technologies and products are planned to be included in the petrochemical and chemical industry's encouraged promotion and application of the technology and product catalog, and will be publicized. The publicity time is from March 24, 2021 to March 30, 2021.

It is understood that the list of technologies and products that are encouraged to be promoted and applied in the petrochemical and chemical industry include the new microchannel reactor equipment and continuous flow process technology recommended by the China Petroleum and Chemical Industry Federation and suitable for the field of fine chemicals and suitable for the petrochemical field. 21 technologies and products including the complete set of reactive distillation technologies. Among them, the new type of microchannel reactor is based on the new type of continuous flow microchannel reaction system, which can be applied to the continuous and efficient synthesis and large-scale production of multiple series of fine chemicals, especially for severe heat release, unstable reactants or products, and material distribution. Than strict, high temperature and high pressure and other dangerous chemical reactions. At present, this technology has been applied to processes such as nitrification, chlorination, oxidation, diazotization, and alkylation.

Six technologies and products, including new technology for high-gravity azo reactor equipment recommended by local economic and information departments, key technology for green preparation of PX oxidation catalysts, and water intelligent technology for petrochemical enterprises are also included in the catalog. Among them, the new technology of high-gravity azo reactor equipment recommended by the Zhejiang Provincial Department of Economy and Information Technology for fine chemicals is developed for the problems of low production efficiency and high labor intensity of traditional batch reactors, which can greatly reduce the risks of the production process. Chemical inventory, to realize the process reengineering and continuous production of the fine chemical production process, and to improve the safety level of the production process. This technology has been applied to the azo reaction of dyes and pigments.

In addition, 5 technologies and products including pipeline integrity management and intelligent analysis and decision-making technology recommended by central enterprises such as Sinopec, Sinochem and China National Chemical Corporation, and new process enhancement technology for p-phenylenediamine antioxidants have been included in the catalog. Among them, the new process enhancement technology for p-phenylenediamine antioxidants recommended by Sinochem Group adopts the noble metal catalytic hydrogenation synthetic rubber antioxidant 6PPD, which can simplify the process, realize continuous production, improve safety, and reduce energy consumption. The technology has been applied in many rubber companies, with consumption reduced by 30%, energy consumption reduced by 20%, unit consumption of raw materials reduced by 5%, and product cost per ton reduced by more than 10%.

Researcher Li Wenjun from the Science and Technology and Equipment Department of the China Petroleum and Chemical Industry Federation told reporters that the technical equipment and products recommended by the Petrochemical Federation have passed the Federation’s scientific and technological achievements appraisal and have been rewarded by the Petrochemical Federation and have been in the industry. Technologies and products successfully applied in many petrochemical companies in China. After these advanced applicable technologies and products are included in the petrochemical industry's encouraged promotion and application catalog, it will help to further increase the promotion of advanced technologies in the whole industry, thereby guiding the technological progress, industrial upgrading, structural adjustment, safety and environmental protection of enterprises in the industry. And green development.
