Abstract
An object of the present invention is to reduce costs while maintaining safety in exhausting hydrogen sulfide gas. In exhaust facilities of a plant for manufacturing hydrogen sulfide gas, the concentrations of hydrogen sulfide gas leaking from a reaction facility, a cooling facility, and a sulfur removal facility, respectively, are measured by a measuring apparatus, and when a detected concentration is less than a predetermined concentration, a valve is controlled to exhaust hydrogen sulfide gas from a first exhaust pipe into the air, on the contrary, when a detected concentration is not less than a predetermined concentration, the valve is controlled to exhaust hydrogen sulfide gas from a second exhaust pipe to a gas treatment facility.
