The report gives results of a study of dual-absorption contact sulfuric acid plants, as well as single-absorption plants equipped with vent gas cleaning systems for removal of SO2, to determine the relationship between process parameters and air emissions. Processes studied were dual-absorption acid plants and single-absorption acid plants equipped with sodium scrubbers, ammonia scrubbers, and molecular sieve adsorbers. Emissions considered were SO2 and acid mist emissions and vent gas opacity. Relationships were developed for normal operations and compared to off-normal operations such as shutdown, start-up, malfunction, and misoperation. Process parameters and emission relationships are presented in statistical, tabular, and graphic form. Converter bed operating temperature ranges were established and causes of SO2 and acid mist emissions are illustrated from plant operating data.
