Wet scrubbers: Match the spray nozzle to the operation
- Lechler GmbH and Co., Metzingen (Germany)
Many industrial processes rely on gas scrubbers to remove unwanted constituents from gas streams. For instance, for flue-gas treatment, wet scrubbers are used to cool and moisten the exhaust stream, and remove SOx, NOx, volatile organic compounds and other volatile organic compounds and other acid gases, and particulates prior to discharge. Wet scrubbers are widely used to treat exhaust streams from power plants, waste incinerators, and stationary diesel engines. They are also used during clinker or cement production. Wet scrubbers rely on a finely atomized stream of liquid to capture particulate and gaseous pollutants from an exhaust stream. Heat and mass transfer are accomplished by the direct contact of the exhaust gas with finely atomized droplets of scrubbing liquid. The rate of chemical or physical reaction between the liquid and gas phases is a function of the amount of surface area the liquid droplets offer. Therefore, selection of the appropriate atomizing nozzle has a direct impact on scrubber performance.
