摘要

The present invention relates to an exhaust gas cleaning equipment comprising a gas scrubber (1) and a scrubber fluid cleaning equipment for cleaning polluted scrubber fluid. The scrubber fluid cleaning equipment comprises a centrifugal separator (9) for separating at least a pollutant phase and a cleaned scrubber fluid from said polluted scrubber fluid. The centrifugal separator has a rotor (11) enclosing a separation space (12) with a stack of separating discs (13) a separator inlet (8) for polluted scrubber fluid extending into said separation space a first separator outlet (14) for cleaned scrubber fluid extending from said separation space and a second separator outlet (15) for the pollutant phase extending from said separation space. The present invention further relates to a method for cleaning polluted scrubber fluid.
