Exhaust gas scrubber, system for treatment of scrubber water and use of an exhaust gas scrubber

摘要

An exhaust gas scrubber (1; 52) for cleaning of exhaust gas (EG) from a combustion engine (2), the exhaust gas scrubber (1; 52) being included in a closed scrubber water circulation loop (13) arranged to circulate scrubber water between a scrubber water circulation tank (15) and the exhaust gas scrubber. The exhaust gas scrubber is arranged to aerate the scrubber water during its passage through the exhaust gas scrubber. The invention further relates to a system for treatment of scrubber water and the use of an exhaust gas scrubber for alternating operation between aeration of scrubber water during its passage through the exhaust gas scrubber and cleaning of exhaust gas from a combustion engine during passage of exhaust gas therefrom through the exhaust gas scrubber
