Wanhua Chemical breaks the foreign technology blockade again and plans to build a 400,000-ton propylene oxide project

After the completion of this project, Wanhua Chemical Group will simultaneously possess three industrial production technologies: PO/MTBE, PO/SM and POCHP, breaking the foreign technology blockade, filling the domestic gap, and making Wanhua the third company in the world to master this technology.

Recently, the official website of Wanhua Chemical Group published a draft of the environmental impact report for the project with an annual output of 400,000 tons of propylene oxide (POCHP)

Project construction background

Propylene oxide (PO) production processes mainly include chlorohydrin method, co-oxidation method, and direct oxidation method

There are 18 existing PO manufacturers in China, with a total capacity of 3.

With the continuous increase of Wanhua Chemical Group’s demand for polyethers, Wanhua’s existing PO production processes have by-products restricted by market uncertainty, while advanced PO processes have always been monopolized by foreign technology, and the development of products is concentrated, with little investment, A PO production process with easy-to-control capacity is imperative

After the completion of this project, Wanhua Chemical Group will simultaneously possess three industrial production technologies: PO/MTBE, PO/SM and POCHP , breaking the foreign technology blockade, filling the domestic gap, and making Wanhua the third company in the world to master this technology.
