Abstract (en)
[origin: WO2005003187A1] The invention relates to a plate column used in the manufacture of PVC by the suspension process to separate the PVC from unreacted VCM. The invention furthermore relates to a method of preventing the formation of a deposit in a plate column and the invention also relates to a novel use of commercially available tangential cone nozzles. To clean the interior of the plate column and/or to prevent the formation of deposits, suspension from the sump portion of the plate column is sprayed into the middle portion thereof.
