Catalyzing hydrogen sulfide in flue gas
Thread Content
Recently, during catalytic flue gas testing, a hydrogen sulfide level of 1000PPM was detected before the flue gas extractor; it is quite puzzling as to how sulfur dioxide and hydrogen sulfide can both be present in the flue gas at the same time Subvert the fundamental theories of organic chemistry! Neither the PFD nor the HAZOP analysis of the foreign process package includes an analysis of this factor and hazard sources; could anyone help provide an interpretation?
Consider the inclusion of oil and gas into the regeneration system for coaxial devices
The catalytic device utilizes foreign-based oxygen-deficient regeneration; with the use of a sulfur transfer agent, magnesium sulfate undergoes a thermochemical reduction reaction with the organic substances on the catalyst under oxygen-deficient conditions, resulting in the formation of hydrogen sulfide, magnesium carbonate, and carbon dioxide. As a result, the flue gas before the CO combustion furnace equipped with this catalytic system contains hydrogen sulfide, which leads to a high level of SO3 in the flue gas after the furnace. This in turn causes more severe problems such as PTU tailing in wet desulfurization processes, acid mist, and blue smoke. Similar processes require close attention when identifying the risks associated with the H2S level in flue gases after the use of sulfur transfer agents; HAZOP analyses should be conducted additionally, and measures should be taken to reduce these risks.
