排ガス及びガス・スクラバ流体浄化装置及び方法
Document Type and Number:
Japanese Patent JP2013527788
Kind Code:
A
Abstract:
The present invention relates to a method for bleeding off a scrubber fluid containing a pollutant phase from a scrubber fluid loop. The invention also comprises use of a bleed-off centrifugal separator for bleeding off a scrubber fluid from a scrubber fluid loop for cleaning exhaust gas, said scrubber fluid containing a pollutant phase. The method and the use involve using a bleed-off centrifugal separator comprising a rotor enclosing a separation space which contains a stack of frustoconical separating discs, a separator inlet extending to said separation space, a first outlet for cleaned scrubber fluid, and a second outlet in the form of discharge ports extending from the separation space for discharge of a separated phase with density higher than the cleaned scrubber fluid. The first separator outlet for cleaned scrubber fluid leads to the outside of a ship for discharge, or to a tank for temporary storage of cleaned scrubber fluid. The second separator outlet is connected to a storage tank for polluted phase.
