Abstract: Because the H2S and SO2 content exceeds the maximum level in tail gas of the Claus furnace system,it has a serious impact on the downstream production after the desulfurization column,i.e.higher H2S in gas and higher sulfide in biological wastewater.The sulfur reactor is upgraded to two-stage reaction,with less tail gas to reduce the heat exchange area of the waste heat boiler.It is also added with one more sulfur separator.

Key words: Claus furnace, Sulfur reactor, Sulfide
