A PROCESS FOR THE OXIDATION OF HYDROGEN SULFIDE TO SULFUR TRIOXIDE WITH SUBSEQUENT SULFUR TRIOXIDE REMOVAL AND A PLANT FOR CARRYING OUT THE PROCESS

摘要

Method for sulfur trioxide oxidation of the hydrogen sulfide that involve the removal subsequent sulfur trioxide is at least one catalyst-containing feeding the effluent from step, and the final reactor for oxidizing hydrogen sulfide to sulfur trioxide in a reactor in the candle filter unit in order to remove SO ₃ comprising the step, where it is mixed with the injected alkaline sorbent slurry or powder forms an alkali sulphate and the high temperature purge gas. Preferably, the oxidation is carried out in two reactors I, the first and the oxidation of H ₂ S on the monolithic catalyst to SO _2, the second is the SO ₂ is oxidized on the VK-type catalyst to SO _3.
