Regarding the Klaus exhaust gas treatment process

This post was last edited by liaifeng on 2018-7-28 07:24. Does anyone know whether it is necessary to carry out hydrogen reduction of SO2 after it passes through the incinerator? Our current level of SO2 is 3,000 milligrams, which is extremely high. We are using products from Hefeng Chaoyou Company, with four reactors in use; the exhaust gas is currently sent to an ammonia-based desulfurization tower. The problem is that a large amount of ammonia is consumed. We would like to further reduce the SO2 levels in the Claus process exhaust gas – is there any efficient process for this purpose? Please suggest some options!
Should we check Scott’s absorption unit? Why is it high behind the incinerator?
No, but there is. Can a catalyst be used at such low SO2 levels?
I suggest trying adding some hydrogen to the third-stage reactor.
The oxygen content in the flue gas after combustion is too high, making it impossible to selectively hydrogenate SO2.
At such a high concentration, ammonia washing cannot solve the problem; direct oxidation in the last stage can be used to send the exhaust gases away.
It seems to make sense; the oxygen level is too high.
There is no problem with the ammonia-based desulfurization tower; our ammonia-based desulfurization method is used in thermal power plants to treat boiler exhaust gases. What does direct oxidation mean?
Selective oxidation – selectively oxidizing hydrogen sulfide into sulfur. Do you have incinerators?
Hello, where are you from? Is the sulfur production process based on the ultra-high-pressure Claus process?
