    摘要: A wet scrubber (1) useful for cleaning a process gas comprises at least a first spray level system (20) and a second spray level system (26) arranged vertically above the first spray level system (20) in a wet scrubber tower (2). The first spray level system (20) comprises at least one gas-liquid contacting plate (38) which is operative for deflecting absorption liquid, that has been atomized by means of the second spray level system (26) and flowing downward in the wet scrubber tower (2), so deflected absorption liquid (AL) may contact process gas (F) contacted by absorption liquid atomized by the first spray level system (20).

    摘要: 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.

    摘要: A method is provided for measuring a concentration of dibasic acid in a substance in a gas cleaning process, the method comprising the steps of sending a plurality of voltage pulses through the substance by a first electrode and a second electrode, wherein the first and second electrodes are in contact with the substance, receiving current responses generated by the plurality of voltage pulses, and analyzing the current responses using a multivariate data analysis for calculation of the concentration of dibasic acid in the substance. Also provided is a dibasic acid sensor, control unit and analysing unit for performing such a method.
