Solvay commissions the largest hydrogen peroxide plant in the world in Thailand

Solvay announced today that MTP HPJV (Thailand) Ltd, its hydrogen peroxide joint venture with The Dow Chemical Company (Dow), has successfully commissioned the largest hydrogen peroxide (HP) 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 that enables such unique, large-scale plants to benefit from advantages in both specific investment and production costs. Solvay’s HP technology also brings significant environmental advantages such as reductions in energy consumption and in waste water.

The plant has a capacity of over 330,000 tons per year of hydrogen peroxide at 100% concentration and serves mainly as a captive raw material source for the manufacture of propylene oxide (PO) by Dow and Siam Cement Group (SCG). Propylene oxide is primarily used to produce propylene glycol, polyurethanes and glycol ethers. It is the second world-scale HP plant dedicated to PO production, the first being the 230,000 tons HP plant (Antwerp, Belgium) commissioned at the end of 2008, which serves a Dow and BASF HPPO plant. Producing PO with HP offers unique and sizeable economic and environmental benefits compared with conventional propylene oxide production technologies.

Although primarily constructed to provide HP for the Dow/SCG HPPO plant, up to a quarter of the new HP plant’s production will also be supplied to Solvay Peroxythai Limited (SPX). SPX is the leading manufacturer of HP in South-East Asia and for over 20 years has been supplying products throughout the Asian region including unique, high purity grades to the food and electronic industries. This new project at Map Ta Phut will allow SPX to more than double its current capacity, consolidating its industry leadership in the region and offering greater long-term security of supply for its customers.

“This new world-class plant gives Solvay the means to bring its Hydrogen Peroxide business to a significantly higher level within this fast growing region and consolidate its position as technology leader”, said Eric Mignonat, General Manager Strategic Development Unit Essential Chemicals at Solvay. “We look forward to serving the very dynamic market and customers”, he added.
