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 RMB 30 billion (USD 5 billion) in these two projects.
According to Steven Wang, Account Manager at Metso, '[the company's] valve solutions were chosen because they meet the strictest standards regarding leakage class and low fugitive emission."
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. Metso will supply ball valves including its X series, D series stemball valves, 9000 series flanged valves, S6 series metal seated high pressure valves, and the R-series V-port segment control valves. Materials of construction range from WCB and CF8M grade to Hastelloy, 316L and Monel per the customer's specification.
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.
