A system for cleaning polluted scrubber fluid from an exhaust gas scrubber is provided. The system comprises a disc stack centrifugal separator for separating at least a pollutant phase and cleaned scrubber fluid from the polluted scrubber fluid, the separator comprising a rotor enclosing a separation space with a stack of separating discs, a separator inlet for polluted scrubber fluid extending into the separating space, a first separator outlet for cleaned scrubber fluid extending from the separating space, and a second separator outlet for a pollutant phase extending from the separating space, a first transportation system for transporting polluted scrubber fluid from an exhaust gas scrubber to the separator inlet, a second transportation system for transporting cleaned scrubber fluid from the first separator outlet back to the exhaust gas scrubber, a bleed-off transportation system connected to the second transportation system for bleeding off part of the cleaned scrubber fluid, a dirty drain tank connected to the bleed-off transportation system for receiving bled-off scrubber fluid, a waste reduction transportation system for transporting scrubber fluid from the dirty drain tank to the first transportation system, and a control unit arranged for receiving information related to the work load of the disc stack centrifugal separator and for regulating the transport of scrubber fluid in the waste reduction transportation system based on the information. |

1. A system for cleaning polluted scrubber fluid from an exhaust gas scrubber, comprising:
a disc stack centrifugal separator for separating at least a pollutant phase and cleaned scrubber fluid from the polluted scrubber fluid, said separator comprising a rotor enclosing a separation space with a stack of separating discs, a separator inlet for polluted scrubber fluid extending into said separating space, a first separator outlet for cleaned scrubber fluid extending from said separating space, and a second separator outlet for a pollutant phase extending from said separating space; a first transportation system for transporting polluted scrubber fluid from an exhaust gas scrubber to the separator inlet; a second transportation system for transporting cleaned scrubber fluid from the first separator outlet back to the exhaust gas scrubber; a bleed-off transportation system connected to the second transportation system for bleeding off part of the cleaned scrubber fluid; a dirty drain tank connected to the bleed-off transportation system for receiving bled-off scrubber fluid; a waste reduction transportation system for transporting scrubber fluid from the dirty drain tank to the first transportation system; and a controller arranged for receiving information related to the work load of the disc stack centrifugal separator and for regulating the transport of scrubber fluid in the waste reduction transportation system based on said information. |
