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. Then, the syngas g is contacted with desulfurizing agentincluding iron oxide. Selection is made whether to further execute deoxidization in a deoxidizing partor omit or simplify the deoxidization according to results of measurements in the preceding measurement part
