Hydrogen sulfide gas production plant system and method for recovering and using hydrogen sulfide gas

摘要

The present invention allows low-concentration hydrogen sulfide gas to be recovered and supplied to a processing plant that uses hydrogen sulfide gas. The hydrogen sulfide gas production plant is provided with a first supply pipe that supplies hydrogen sulfide gas obtained from a sulfur recovery facility to a processing plant, and a second supply pipe that is branched at a predetermined point in the first supply pipe and supplies the hydrogen sulfide gas from the sulfur recovery facility to the processing plant. The first supply pipe has a concentration meter that is provided on the upstream side than the branch point and measures the concentration of the hydrogen sulfide gas. The first supply pipe and the second supply pipe have ON/OFF valves that are provided on the downstream side of the branch point and perform ON/OFF control of the supply to the processing plant through the supply pipe.

1. A hydrogen sulfide gas production plant system, comprising:
a plurality of systems of hydrogen sulfide gas production plants provided with at least a reaction facility that generates hydrogen sulfide gas from sulfur and hydrogen gas, a plurality of cooling facilities that cool the generated hydrogen sulfide gas, and a sulfur recovery facility that recovers sulfur contained in the hydrogen sulfide gas, the hydrogen sulfide gas production plant system that: the hydrogen sulfide gas production plant of each system is provided with a first supply pipe that supplies the hydrogen sulfide gas from which sulfur has been recovered in the sulfur recovery facility to a processing plant that uses hydrogen sulfide gas, and a second supply pipe that is branched at a predetermined point in the first supply pipe and supplies the hydrogen sulfide gas from the sulfur recovery facility to the processing plant; the first supply pipe has a concentration meter that is provided on the sulfur recovery facility side than the predetermined branch point and measures the concentration of the hydrogen sulfide gas; and the first supply pipe and the second supply pipe each have an ON/OFF valve that is provided on the processing plant side than the predetermined branch point and turns ON/OFF the supply of the hydrogen sulfide gas to the processing plant through the supply pipe.
