Abstract:
It is an object of the present invention to downsize facility for removing or reducing concentration of hydrogen sulfide and oxygen in gas and reduce facility cost. Syngas g contains hydrogen sulfide and oxygen as target constituents of removal or reduction in concentration. Hydrogen sulfide content and oxygen content in the syngas g are measured in a preceding measurement part  13.  Then, the syngas g is contacted with desulfurizing agent  14 a  including iron oxide. Selection is made whether to further execute deoxidization in a deoxidizing part  16  or omit or simplify the deoxidization according to results of measurements in the preceding measurement part  13.

Claim (Index 3):
The method for treating gas according to  claim 1 , wherein\n transition metal oxide is contacted with the gas in the contacting step, the transition metal oxide becoming a product that is reactable with oxygen by reaction with the hydrogen sulfide, and selection is made whether to add hydrogen sulfide or a sulfur compound other than the hydrogen sulfide to the gas before or during the contacting or omit the adding according to the results of the measurements or demand by a utilizing part of the gas.
