〈Sulfur recovery issue

When a Klaus catalyst is operated at low load, is it easy to control the temperature rise, and what impact does this have on the catalyst?
Under low-load operation, the temperature rise of the reactor is small and difficult to control; if the flow rate is too low, the system is prone to clogging, resulting in excessive exhaust emissions.
Generally, the temperature rise in the bed is very small; excessive oxygen can lead to a reduction in the catalyst’s lifespan, but it’s not a major issue.
At low load, the temperature of the burner may not meet the requirements; if fuel gas is used, it has a significant impact on the catalyst. Reduce catalyst service life
