Recovery
|
In the Recovery Section, unconverted VCM is removed from the PVC slurry. VCM gas is vented from the degasser to the gasholder, and remaining VCM dissolved in the polymer is removed by live steam in the stripper. The recovered VCM gas is compressed, cooled and liquefied; water is separated, and the VCM liquid is returned to VCM storage for re-use. Almost all of the VCM that has not been used in the PVC batch is recovered and reused.
