Yangnong Group built the world’s first continuous, automated production facility for ECH using the hydrogen peroxide method, with an annual production capacity of 150,000 tons; this facility began operating on an industrial scale in March 2022. This project is in line with the concept of \"green development\" and represents an environment-friendly manufacturing process that is encouraged for development. Achieving cleanliness and safety in the production process at its source has a significant demonstrative and leading effect; it helps to enhance Yangnong Group’s position in the industry and drives its sustainable development. This is the world’s first set of devices of this type. The green and clean production technology employed in it has passed the evaluation for scientific and technological achievements by the China Petroleum and Chemical Industry Federation; the conversion rate of hydrogen peroxide is ≥99%, the utilization rate is ≥98%, the selectivity for epichlorohydrin is as high as 99%, and the content of epichlorohydrin in the product is ≥99.9%. The overall technology of this project is at an internationally advanced level, while the performance of the catalysts is at the international leading level. In November 2022, the appraisal meeting for the scientific and technological achievement of Yangnong Group’s \"150,000 tons per year green production technology of epichlorohydrin using the hydrogen peroxide method\" was held in Beijing and was a complete success.
