Phosgene is an intermediate chemical used in the manufacture of Isocyanates, Chloroformates, Acid Chlorides, and specialty chemicals. Because Phosgene is toxic, reliable facilities with minimum inventory are required for personal safety. Chemical Design, Inc. has designed and built Phosgene plants ranging from 0.5 to over 160 tons / day of high purity Phosgene. State-of-the-art bellows seal valves are used to virtually eliminate emissions. Our compact, skid mounted phosgene reactor design allows the entire reaction system to be installed inside a controlled building which acts as secondary containment. The complete plant allows Phosgene to be safely produced onsite, on demand, thereby eliminating transportation and storage concerns.
