Sulphur recovery and tail gas treatment
gas from the sulphur recovery process into the tail gas treatment section. Combustion air is fed to both the reaction and reduction furnaces. An optimal amount of air ensures that complete combustion occurs without excess oxygen passing through to the reactors. The reduction furnace uses separate fuel gas, usually natural gas, to permit combustion.
