Evonik and thyssenkrupp Industrial Solutions are licensing their HPPO technology for the production of propylene oxide to the Chinese chemical company Zibo Qixiang Tengda Chemical. thyssenkrupp will be responsible for the process design and supply key components for the new plant. In addition, Evonik is licensing hydrogen peroxide (H2O2) technology to Qixiang Tengda for the exclusive supply of the propylene oxide plant. The partners have also signed a long-term supply contract for the corresponding HPPO catalyst.
Over the next few years, Qixiang Tengda will build a plant complex at its Zibo site (Shandong Province, China) that will be capable of producing up to 300,000 metric tons of propylene oxide per year as well as the H2O2 required for the HPPO process. Initial engineering work is scheduled to start in mid-August 2019. The plant is expected to come on stream in the H1 of 2022.
HPPO stands for âHydrogen Peroxide to Propylene Oxideâ?. The HPPO process requires significantly lower investment and is more cost-efficient. In addition, it is extremely environmentally friendly because it is highly selective and no by-products other than water are produced in significant quantities.
