IP & E APPLICATION
VINYL CHLORIDE MONOMER ( VCM ) PRODUCTION
VCM is an important intermediate product for the production of polyvinyl chloride ( PVC ). It is created by reacting hydrogen and chlorine ( Cl 2 ) together 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 Cl 2 stream to avoid compressor corrosion , safety measurements for both HCl and Cl 2 , and oxygen measurements in the acetylene stream .
Challenging process conditions , such as condensation and corrosion , can affect the gas analysis equipment used in this process . The analytical systems used 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 .
KEY SOLUTIONS
SERVOTOUGH SpectraExact 2500
The rugged SERVOTOUGH SpectraExact 2500 accurately provides single and multi-component analysis at key process points , including measurements for moisture in Cl 2 to protect the compressor from corrosion damage . It can also make the necessary measurements for HCl and Cl 2 concentrations between the HCl reactor and preheater stages of the process .
