Abstract
An object is to provide a hydrogen sulfide gas production plant that can recover discharged waste hydrogen sulfide gas and efficiently supply the gas to a process plant where processing is conducted by using hydrogen sulfide gas, and also provide a method for recovering and using the waste hydrogen sulfide gas by the hydrogen sulfide gas production plant. In the present invention, the hydrogen sulfide gas production plant is provided with a pipe that recovers the waste hydrogen sulfide gas discharged from the hydrogen sulfide gas production plant and that has one end connected to the process plant where the hydrogen sulfide gas is used, and the discharged waste hydrogen sulfide gas is recovered and the recovered waste hydrogen sulfide gas is supplied to the process plant through the pipe.
