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

Abstract: A method and apparatus or system is provided for cleaning a flue gas and/or cooling a flue gas with a dispersed finely divided absorption liquid. As such, the absorption liquid is dispersed in a wet scrubber through which flue gas flows for absorption liquid and flue gas intermingling and contact to produce a cleaned flue gas. The absorption liquid supplied to the wet scrubber is dispersed from upwardly spraying anti-clogging nozzles and downwardly spraying nozzles arranged to maximize absorption liquid and flue gas contact with minimal spray interference between nozzles.

Abstract: A system and method for controlling oxidation of sulfites in a slurry. The system includes a tank having an inlet for receiving a slurry used in wet flue gas desulfurization. The tank also includes an inlet for receiving a gas. The inlet for receiving the gas is configured so that at least a portion of the gas received in the tank is dispersed through at least a portion of the slurry received in the tank. A sensor is configured to measure a sulfite concentration S1 of the slurry received in the tank. In some embodiments, the sensor is a sulfite analyzer. In other embodiments, the sensor is a virtual analyzer. The system includes a controller. Software executing on the controller generates a signal indicative of an adjustment of a flow rate of gas into the tank based at least in part on the sulfite concentration S1.
