A process and a plant for the production of sulfuric acid from a coke oven gas desulfurisation product.

摘要

A process for the production of sulfuric acid from a gas containing H2S and HCN is carried out in a process plant comprising an alkaline absorber, means for separation, an incinerator, a particulate removal device for separating solid particles from the process gas, and means for provision of concentrated sulfuric acid. The plant can further comprise means for obtaining a reduced NOx content and a sulfur dioxide converter comprising a material active in oxidation of SO2 to SO3 eventually being converted to sulfuric acid.
