Instruments Tame Troublesome Slurry

摘要

LUBRIZOL ADVANCED Materials' Louisville, Ky., plant produces chlorinated polyvinyl chloride (CPVC) resin by reacting chlorine and PVC. To transport resin from vessel to vessel, the CPVC is mixed with water. A centrifuge later dewaters the slurry. Some CPVC grades then require dosing a very small amount of an additive chemical before going to a fluid-bed dryer to produce the final resin powder.
