Abstract:
A wet scrubber (1) for cleaning a process gas containing sulphur dioxide comprises an absorption vessel (2) for contacting the process gas with an absorption liquid to absorb sulphur dioxide from the process gas, a sulphite sensor (68, 74) for measuring a sulphite concentration in the absorption liquid, and a control unit (52). The control unit (52) is adapted to receive a measurement signal from the sulphite sensor (68, 74) and to control, based on the measured sulphite concentration, at least one wet scrubber operating parameter influencing the sulphite concentration in the absorption liquid.
