Abstract: A cleaning system for reducing SOx and particulate matter in exhaust gases from a marine combustion engine, burner or boiler. The cleaning system comprises first and second scrubber process loops having first and second scrubber, respectively, and first and second water circulation tanks, respectively. Water from the first tank is evaporated to water vapor inside the first scrubber by contact with the exhaust gases, whereby the water vapor and the exhaust gases form humid exhaust gases. The humid exhaust gases are transferred to the second scrubber, wherein water from the second tank condensates the water vapor in the humid exhaust gases. A reflux of water from the second scrubber process loop to the first scrubber process loop is provided. At least 60% and more preferred at least 90% of a total amount of alkaline agent supplied to the cleaning system is supplied to the second scrubber process loop.

Abstract: A system, a use of such a system and a multi system for cleaning exhaust gas from a combustion engine. The system comprises a first exhaust gas scrubber to communicate with a scrubber water circulation tank. A first outlet of the first exhaust gas scrubber is connectable to a first inlet of the scrubber water circulation tank, and a first inlet of the first exhaust gas scrubber is connectable to a first outlet of the scrubber water circulation tank, to enable circulation of scrubber water between the scrubber water circulation tank and the first exhaust gas scrubber. An air supply device feeds air into the first exhaust gas scrubber to aerate the scrubber water during its passage through the first exhaust gas scrubber. Accordingly, a second inlet of the first exhaust gas scrubber is arranged to be connected to an outlet of the air supply device.
