Abstract
Hard chromium plating is extensively used in the industry to improve the wear characteristics of metal parts. EPA has identified hexavalent chromium, used in chromium plating, as one of the 17 high-priority toxic chemicals. The purpose of this project was to design a new process that will prevent the release of chromic-acid mist into the workplace. Traditionally, temperature control and mixing have been achieved by bubbling air at the bottom of the plating bath using a sparger. These air bubbles burst at the surface of the plating solution and produce aerosols that are responsible for the chromium emissions. The proposed process uses a silicone fluid layer at the top of the plating solution to trap the aerosols. Mixing and heat transfer are achieved by sparging this fluid. Mathematical models have been developed to predict hexavalent chromium emissions, heat transfer, and health risks associated with conventional plating tanks.
