Vinyl chloride monomer

Servomex delivers analysis solutions for VCM production

Vinyl chloride monomer (VCM) is an important intermediate product for the production of PVC. We provide the industry-leading gas analysis solutions you need to deliver key measurements while overcoming condensation and corrosion issues.

Key process points for gas analysis

VCM is created from the reaction of hydrogen and chlorine (Cl2) to form hydrogen chloride (HCl), which in turn is combined with acetylene to produce VCM. Gas analysis measurements are required across the process, including monitoring moisture in the Cl2 stream to avoid compressor corrosion, safety measurements for both HCl and Cl2, and oxygen measurements in the acetylene stream.

Accurate measurements in difficult process conditions

Challenging process conditions, such as condensation and corrosion, can affect the gas analysis equipment used in this process. Analytical systems must not only deliver reliable measurements for process control and safety, but have to be able to do so without being impaired by the conditions themselves.

A solution for safety and protection against corrosion

The rugged SERVOTOUGH SpectraExact 2500 is able to accurately provide single and multi-component analysis at key process points, including measurements for moisture in Cl2 to protect the compressor from corrosion damage. It can also make the required measurements for HCl and Cl2 concentrations between the HCl reactor and preheater stages of the process.
