• Description:
  A program implemented to contain and eliminate the exposure of employees to vinyl-chloride (75014) during the opening of the polyvinyl-chloride (9002862) (PVC) polymerization reactors to remove polymer buildup was described. Elimination of reactor fouling was achieved by developing reactor cleaning technology based on the introduction of high pressure water jets, using nozzles inserted into the reactor. Removal of the buildup was successfully achieved by developing a simple and effective commercial system consisting of a chemical feed tank, a pump and a feed nozzle used with the reactors where vinyl-chloride was polymerized to PVC. The operation involved the rinsing with water of the loose resin present in the reactor following each polymerization operation, followed by spraying of a coating solution onto the internal areas of the reactor. The application of the new technology in closed reactor operation, reduction of worker exposure to vinyl-chloride monomer, savings in labor, reduction of reactor down time, increased productivity and improved processing conditions were discussed.
