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 |
A process for the oxidation of hydrogen sulfide to sulfur trioxide with subsequent sulfur trioxide removal comprises oxidizing hydrogen sulfide to sulfur trioxide in at least one catalyst-containing reactor and feeding the effluent from the last reactor to a candle filter unit for SO3 removal, where it is mixed with an injected alkaline sorbent slurry or powder to form an alkali sulfate and a hot clean gas. Preferably the oxidation is done in two reactors, the first oxidizing H2S to SO2 over a monolith type catalyst and the second oxidizing SO2 to SO3 over a VK type catalyst. |
