Abstract
A process and a process plant for conversion of SO2 to H2SO4 including a. directing a process gas stream including at least 15 vol % SO2, and an amount of O2 originating from a source of purified O2 or O2 enriched air to contact a first material catalytically active in oxidation of SO2 to SO3 under oxidation conditions involving a maximum steady state temperature of the catalytically active material above 700° C., to provide an oxidized process gas stream, wherein the material catalytically active in oxidation of SO2 to SO3 includes an active phase in which the weight ration of vanadium to other metals is at least 2:1 supported on a porous carrier comprising at least 25 wt % crystalline silica, b. absorbing at least an amount of the produced SO3 in a stream of lean sulfuric acid to provide a stream of liquid sulfuric acid.
