Abstract
A method for controlling mercury release, emission and/or re-emission levels in a treated flue gas and a seawater effluent waste stream through control of a sulphite concentration within a seawater scrubber system is disclosed. One method for controlling mercury release, emission and re-emission levels through control of sulphite concentration is to measure the sulphite concentration of seawater entering a seawater scrubber system and comparing the same to a predetermined sulphite concentration value. If the comparison reveals the measured sulphite concentration is above the predetermined sulphite concentration values, the amount of fresh seawater and/or oxidation air supplied to the seawater scrubber system is increased. If the comparison reveals the measured sulphite concentration is below the predetermined sulphite concentration values, the amount of fresh seawater and oxidation air supplied to the seawater scrubber system is decreased.
