Modeling and Simulation of Claus Unit Reaction Furnace

2019-8-1·third of the hydrogen sulfide to sulfur dioxide are fed through the reaction furnace. In the reaction furnace, about 60-70% of the H 2 S in the feed gas stream is converted to the elemental sulfur. As the furnace reactions are highly exothermic, valuable steam can be generated in the waste heat boiler that locates after the furnace.
