Abstract
PURPOSE: To remove H2S, stably, efficiently, without increasing the thermal loss, by utilizing the heat of catalytic oxidation of H2S in the gas at the upper stream of the gas flow in a Claus catalyst as the heat necessary for the reaction of H2S and SO2 on the Claus catalyst.
CONSTITUTION: The gas discharged from the Claus furnac 1 contains H2S, SO2 and S. S is condensed and removed in the apparatus 2A, and the residual gas is introduced together with introduced air into the Claus reactor 3A. The reactor is provided with an H2S oxidation catalyst layer 5A, in which the introduced gas is heated by the oxidation reaction of H2S contained therein. The heated gas is introduced into the Claus catalyst layer 4A. Consequently, the Claus catalyst layer 4A is maintained at a preset temperature adequate to form S stably by the reaction of H2S and SO2 and to prevent the clogging of the catalyst layer 4A by the condensation of S vapor in the layer. The produced S vapor is condensed and recovered by the apparatus 2B, and the residual gas is successively treated in the Claus reactor 3B in a similar way. The temperature of the gas introduced into the layer 4 is detected by the temperature detector 6 and controlled by adjusting the amount of intruduced air with the valve 7 operated by the controller 8 according to the signal from the detector 6.
