Abstract

See full text

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.
