Zhenhai Branch of Zhenhai Chemical & Chemical Co., Ltd. is the largest petrochemical production unit with a single set of joint ventures of Sinopec, and is the largest in the world. In the PO/SM production process, a large amount of volatile organic waste gas is generated. The plant's exhaust gas treatment link was originally planned to introduce catalytic oxidation technology from abroad, but in order to reduce investment and operating costs, the localization of PO/SM exhaust gas catalytic oxidation treatment technology was promoted. Sinopec Zhenhai Refining & Chemical Branch, Fushun Petrochemical Research Institute and Luoyang Petroleum The three parties of the Chemical Engineering Company formed the research group and successfully developed the self-contained technology.
The main contents of the development of PO/SM exhaust gas catalytic oxidation process technology include catalyst formulation and preparation, process technology package, engineering design technology and operation and operation technology. The complete set of technology features high catalyst activity, long life, low operating temperature, and low energy consumption. The complete set of technology has successfully implemented industrial applications on large-scale devices, significantly reducing the investment in equipment construction and operating costs, and has been approved by PO/SM patents.
The technology currently has 5 Chinese invention patents. Compared with the use of foreign technologies of the same type, investment in device construction can save more than 35 million yuan, and can be promoted and applied in the field of organic waste gas emissions from acrylonitrile, phenol acetone and Other devices, with significant economic and social benefits.
The complete catalytic oxidation treatment of PO (propylene oxide)/SM (styrene) exhaust gas with independent intellectual property rights and alternative import technology was successfully developed by Sinopec Fushun Petrochemical Research Institute, Zhenhai Refinery Branch and Luoyang Petrochemical Engineering Company. The realization of industrial applications has recently passed the technical appraisal of Sinopec in Beijing and the overall technology has reached the international advanced level.
