Title: Preparation of sulfur from gas containing so2
Inventor: SEIKE YASUHIKO
IPC: C01B17/04
Filed: 1981-07-01
Abstract: PURPOSE:To keep the Claus ratio[molar ratio of H2S to SO2 or (H2S+COS) to SO2]of a gas at the outlet of an SO2 reduction reactor at an optimal value in preparing sulfur using the SO2 reduction reactor and a Claus reactor in combination, by specifying the SO2 conversion rate in the SO2 reduction reactor. CONSTITUTION:A gas, containing SO2, and supplied with additional air is fed to an SO2 reduction reactor to reduce SO2 partially into vaporous S, which is then condensed and separated from the outlet gas of the reactor. The excess gas is introduced into a Claus reactor to produce the vaporous S. The air blowing ratio to the gas containing SO2 fed to the SO2 reduction reactor is adjusted to keep the SO2 conversion at 75-85%, and the Claus ratio of the outlet gas of the reactor can be kept at about 2. The air blowing ratio refers to the ratios of the air blown into the reactor to the unit flow rate of the gas containing SO2, and varies somewhat with the kind of carbonaceous granules used as a reducing agent in the SO2 reduction reactor. If the kind is fixed, there is a fixed correlation between the SO2 conversion rate and the air blowing ratio.
