  • CLEANING APPARATUS FOR GAS SCRUBBER FLUID
    Publication number: 20130157833
    Abstract: A cleaning apparatus for polluted scrubber fluid from an exhaust gas scrubber fluid loop includes means for bleeding off part of the polluted scrubber fluid from the scrubber fluid loop, a disc stack centrifugal separator for separating a pollutant phase and a cleaned scrubber fluid from said part. The separator includes a rotor enclosing a separation space with a stack of separating discs, a separator inlet extends into the separating space, a first separator outlet for cleaned scrubber fluid extending from said separating space, and a second separator outlet for the pollutant phase extending from the separating space. The cleaning apparatus includes means for conducting the part to the separator inlet, and means for discharging the cleaned scrubber fluid from the first separator outlet, and means for collecting the pollutant phase from the second separator outlet.
