Abstract
A method of reducing the hydrogen sulfide content of an influent gas stream comprising oxygenated gas and hydrogen sulfide. An aqueous stream including an available metal chelant and the influent gas stream are contacted using an eductor. The eductor releases an eductor effluent stream including a mixture of sulfur, a first treated gas including a lower concentration of hydrogen sulfide than the influent gas stream, a first unavailable metal chelant, the available metal chelant. The eductor effluent stream is received in a common vessel wherein a plurality of activities may be performed. The plurality of activities includes generating a second treated gas by reducing a metal of the available metal chelant and producing the aqueous stream of the available metal chelant by oxidizing the first or second unavailable metal chelant using the oxygenated gas.
