MOSCOW (MRC) -- Qixiang Tengda’s new propylene oxide complex in Zibo City, China, using technology from Evonik and thyssenkrupp Uhde have become operational, said Specialchem.
The technologically integrated setup offers significant ecological and economic benefits compared to conventional production methods for propylene oxide.
With the capacity to produce 300,000 tons of propylene oxide each year, the state-of-the-art complex involves two main plants: One is a world-scale HPPO facility to synthesize propylene oxide directly from hydrogen peroxide using a method licensed from Evonik and thyssenkrupp Uhde.
The other is a new hydrogen peroxide mega plant licensed from Evonik to provide the raw material directly on-site. Evonik is also supplying its catalyst specifically designed for the process.
HPPO, or “hydrogen peroxide to propylene oxide,” is an efficient propylene oxide production method developed by Evonik and thyssenkrupp Uhde. Through HPPO, propylene oxide can be synthesized directly from hydrogen peroxide without generating any co-products other than water.
It is enabled by a catalyst developed and continuously improved by Evonik specifically for this purpose. Through this combination of streamlined chemical process and high-performance catalyst, HPPO slashes energy and resource use, saves emissions, reduces costs, and avoids unwanted co-products compared to conventional propylene oxide production.
In addition, the on-site hydrogen peroxide mega plant, licensed by Evonik and also running an Evonik catalyst, ensures the highest standards in terms of safety, supply security, and quality of the crucial raw material. More than a century of worldwide expertise in peroxides has made Evonik a global technology leader in hydrogen peroxide, as well as now the first company operating and licensing a hydrogen peroxide mega plant in China.
We remind, LANXESS has doubled its production capacity for benzyl alcohol at its site in Kalama, WA, US, to support the growth of its established customer base in the Americas. The capacity expansion is the result of various technical upgrades. LANXESS also produces benzyl alcohol at its sites in Krefeld-Uerdingen (Germany), Botlek (Netherlands), and Nagda (India).
