Abstract
A process for producing concentrated contact sulfuric acid in which hot gases are produced by roasting sulfur concentrates containing mercury or mercury compounds and said gases are subsequently passed through cooling and purification steps, followed by drying steps., conversion and absorption, to produce sulfuric acid; characterized in that sulfur is added to the hot gas stream before the entry of said stream into the cooling and purification stages, thereby reducing the mercury content of the gases leaving the purification stage and of the acid produced.
