Abstract
A method and system for removing at least dissolved hydrogen sulphide or another targeted constituent from a feedstock is provided wherein the targeted constituent has a gas: liquid equilibrium. In some embodiments, the method includes the steps of: contacting the feedstock in at least one stripping vessel with a stripping gas to produce a gas stream containing at least hydrogen sulphide gas; conveying the gas stream from the at least one stripping vessel to an oxidation reactor; contacting the gas stream with an oxidizing agent in the oxidation reactor so as to oxidize the at least hydrogen sulphide gas to produce sulphuric acid; and conveying the produced sulphuric acid from the oxidation reactor to the at least one stripping vessel so as to reduce a pH value of the feedstock within the stripping vessel.
