MTP HPJV (Thailand) Ltd., a hydrogen peroxide joint venture of Solvay and Dow, has successfully commissioned the largest hydrogen peroxide plant in the world. The production process of the new plant in Map Ta Phut, Thailand, is based on Solvay’s proprietary, high-yield hydrogen peroxide technology.

The plant has a capacity of over 330,000 t/a of H₂O₂ at 100 % concentration. It serves mainly as a captive raw material source for the manufacture of propylene oxide (PO) by Dow and Siam Cement Group (SCG). PO is primarily used to produce propylene glycol, polyurethanes, and glycol ethers. Producing PO with H₂O₂ offers unique and sizeable economic and environmental benefits compared with conventional propylene oxide production technologies.

Up to a quarter of the new H₂O₂ plant’s production will also be supplied to Solvay Peroxythai Limited (SPX), the leading manufacturer of H₂O₂ in South-East Asia.
