PLANT FOR MANUFACTURING HYDROGEN SULFIDE GAS AND METHOD FOR EXHAUSTING HYDROGEN SULFIDE GAS

摘要

The purpose of the invention is to reduce costs while maintaining safety when exhausting hydrogen sulfide gas. In an exhaust facility for a plant for manufacturing hydrogen sulfide gas, the concentration of hydrogen sulfide gas leaking from reaction facilities, cooling facilities, and sulfur elimination facilities is measured by a measuring apparatus, and valves are controlled when the detected concentration is less than a prescribed concentration to exhaust hydrogen sulfide gas into the air from a first exhaust pipe. When the concentration is above that prescribed, the valves are controlled to exhaust the hydrogen sulfide gas from a second exhaust pipe to a gas treatment facility.
