ABSTRACT:
A process for the removal of water from dispersed particles such as vinyl resins uses electrofiltration to yield a high total solids content wetcake. A final dryer such as a fluid energy dryer is used to yield a dry, finely divided resin or polymer. Accordingly, the need for various spray drying methods accompanied by subsequent harsh grinding steps are eliminated. Substantial energy cost savings are realized and the need for coagulation additives are eliminated as well as the necessary removal and neutralization of undesirable residues.
