| 摘要 |
The invention relates to a combined cleaning system to be used in a wet scrubber process for the reduction of SOX and NOX in exhaust gases from a combustion engine (2). The system comprises an Exhaust Gas Cleaning (EGC) scrubber (1) and an Exhaust Gas Recirculation (EGR) scrubber (11). The combined cleaning system further comprises a scrubber water circulation tank (15) arranged to circulate scrubber water in an EGC scrubber process loop (13) between the scrubber water circulation tank (15) and the EGC scrubber (1) and in an EGR scrubber process loop (14) between the scrubber water circulation tank (15) and the EGR scrubber (11). The EGR scrubber process loop (14) comprises an arrangement (39) for supply of a first alkaline agent to the flow of scrubber water and a first separator unit (29) for the purpose of separating particulate matter from the circulated scrubber water. The invention also relates to a method for the reduction of SOX and NOX in exhaust gases from a combustion engine (2) by using a combined wet scrubber cleaning system. Further, the invention relates to the use of the combined cleaning system on-board a ship. |
