Metso has been awarded a high-value contract for pneumatic ball valves and butterfly valves by Yantai Wanhua Polyurethanes Limited. The valves will be used in the MDI integration project (diphenymethane disocyanate) at their existing factory site and a new PO/AE integration project under construction in China (epoxy propane and acrylic ester). This is the first partnership between Metso and Yantai Wanhua, which has invested approximately $5 billion in these two projects.
The PO/AE integration project includes plants for propane dehydrogenation, acrylate, and acrylic acid resin, propylene oxide, and polyhydric alcohols, as well as a LPG storage cavern.
The key components of the MDI project, which includes plants for producing isocyanate, oxidized hydrogen chloride, and nitrobenzene, require valves that deliver a superior tightness in difficult applications over long time and which promise control of fugitive emissions.
