In the production of sulfuric acid, the final step is to clean the exhaust gases from the sulfuric acid mist. Currently, many industrial enterprises have abandoned the use of electrostatic precipitators to catch acid droplets in favor of the use of bag filters. The authors conducted an experimental study of the effectiveness of various filter materials and their combination in the form of a bag for catching sulfuric acid fog. A filter package was proposed from layers of fiberglass and fluoroplastic materials for industrial use, which showed a 98% efficiency for cleaning exhaust gases from a sulfuric acid mist.
