Ethylene oxide production of Sinopec and South Korea reaches a record high

As of 0:00 on December 31, 2019, the epoxyethane (EO) produced by the epoxyethane Department of Sinopec was 170412 tons, breaking 170000 tons for the first time, a record high since the unit was put into operation In recent years, the ethylene oxide Market produced by Sinopec and South Korea is in short supply, and its gross profit ranks first among the company's more than 20 organic chemical products In 2019, the EO / EG unit of the company's epoxy aromatics Department overcame the problem of over design cycle operation of catalyst and actively eliminated the bottleneck of high load production From the aspects of safety, environmental protection, process and equipment, they implemented more than 10 high-temperature production countermeasures, focused on raw material reaction, catalyst activity, and optimized refrigeration conditions of ice machine to ensure high and stable production in summer In view of the fact that the silver catalyst has reached the end of operation, the unit has vigorously carried out the technical research of long-term operation of silver catalyst, formulated a plan, paid close attention to the heating rate of oxidation reactor, and strictly controlled the reaction temperature of silver catalyst In order to reduce the decline of product quality due to the decrease of catalyst selectivity and activity, the unit continuously optimizes and adjusts the operation strategy of silver catalyst By optimizing the amount of inhibitor added, increasing the catalyst activity properly, strengthening the site management and other measures, the fine adjustment and fine control are carried out, and the operation parameters are continuously optimized, so as to lay a solid foundation for high and stable production throughout the year.
