SBB Holdings will use the new HPPO process to build PO units that use hydrogen peroxide (H2O2) and propylene to produce propylene oxide (PO) at a low cost. This process was jointly developed by Evonik and Wood, and has been transferred to other chemical companies.
In mid-January of this year, Evonik partnered with its US joint venture partner Headwaters to complete the expansion of the Ulsan hydrogen peroxide device in South Korea. The H2O2 produced by this device is directly supplied to the Korean market and supplied to SKC in Seoul. . Recently, SKC's new HPPO process will be put into production.
Evonik of Germany and Sibur of Russia signed an agreement at the end of March to conduct a feasibility study on the construction of a propylene oxide (PO) plant in Russia.
