Abstract
Способ получения серной кислоты из сероводородсодержащего газа, включающий стадии сжигания, денитрификации, конверсии сернистого газа, конденсации кислоты, отличающийся тем, что денитрификация производится путем одновременного введения двух стадий: предварительной водной промывки сероводородсодержащего газа и финишной обработки серной кислоты восстановителем, причем количество воды для предварительной водной промывки составляет 5-50% от веса сероводородсодержащего газа, а в качестве восстановителя используются или гидразин, или гидразинсульфат, или гидроксиламин, или сульфат аммония, или карбамид.A method of producing sulfuric acid from a hydrogen sulfide-containing gas, comprising the stages of burning, denitrification, conversion of sulfur dioxide, condensation of acid, characterized in that denitrification is carried out by simultaneously introducing two stages: pre-washing the water with hydrogen sulfide gas and finishing the sulfuric acid with a reducing agent, the amount of water for preliminary water washing amounts to 5-50% by weight of hydrogen sulfide-containing gas, and either hydrazine or razinsulfat or hydroxylamine, or ammonium sulfate or urea.
