Map Ta Phut, Thailand - Solvay says its 330 kilotonnes per annum hydrogen peroxide plant, commissioned in early October, is the largest in the world.
The plant, at Map Ta Phut in Thailand, MTP HPJV (Thailand) Ltd, is a joint venture with Dow Chemical Co. and will mainly supply raw material for propylene oxide (PO) production by Dow, using the hydrogen-peroxide-to-PO (HPPO) route.
Solvay is using its proprietary, high-yield hydrogen peroxide technology that it says enables such unique, large-scale plants to benefit from advantages in specific investment and production costs. Also, Solvay says, its HP technology has environmental advantages -- such as reductions in energy consumption and in waste water.
Dow and Siam Cement Group (SCG) have a joint venture propylene oxide at Map Ta Phut, with the PO primarily used to produce propylene glycol, polyurethanes and glycol ethers.
This is Solvay's second world-scale HP plant dedicated to PO production, the first being a 230 ktpa plant at Antwerp, Belgium, commissioned at the end of 2008, which serves a joint Dow/BASF HPPO plant.
Producing PO with HP offers sizeable economic and environmental benefits compared with conventional technologies, said Solvay.
Up to a quarter of the Thai plant's hydrogen peroxide production will be supplied to Solvay Peroxythai Ltd (SPX), which Solvay said is the main manufacturer of HP in South-east Asia, supplying products throughout Asia including unique, high purity grades to the food and electronic industries.
This new plant 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.
