Reduction of Vinyl Chloride Monomer Concentration in Poly Vinyl Chloride

Shukla Harsh B | Shukla Akanksha H

Abstract: The polymerization reaction in the reactor takes place by means of chain-growth polymerization of Vinyl Chloride Monomer (VCM). To make the Polyvinyl Chloride (PVC) as per the requirements of the consumer market, many other additives are added into it. This paper is based on suspension polymerization method for PVC production. The monomer recovery section recovers residual amount of the VCM from final PVC slurry. The final PVC slurry is sent to filtration, drying and bagging & packing section. The excess amount of VCM in it will cause some severe problems. Excess VCM amount causes severe effects on environment, product economy as well as on process part. Focus of this paper is on finding out all possible sources which are causing this problem of excess VCM into the final PVC slurry.
