Abstract
Electroplating industry has by-products, most of which are harmful. The paper considers the issue of removing aerosol emissions during chrome coating. We developed a droplet separator, which was granted a patent for a useful model. Based on the model, we proposed a stage-by-stage technical procedure for cleaning gas-air mixture to optimize the performance of gas-cleaning equipment during hard chrome coating. We calculated the amounts of water vapor and chromic anhydride which is released during chrome plating without cleaning and when using the developed procedure for gas mixture cleaning. We determined maximum surface concentrations of pollutants in exhaust gases after cleaning.
