Abstract

The invention concerns a method and an apparatus for purifying combustion gases, especially combustion gases exhausted from maritime diesel engines and combustion gases produced by power plants situated near the seaside, of impurities contained in the combustion gases. The apparatus comprises a scrubber device (10) for scrubbing the combustion gases and a droplet separator device (20) for separating scrubbing liquid droplets from the outflowing purified combustion gas flow (D). The scrubber device (10) comprises an inflow duct (13) for conveying an overpressurised combustion gas flow (A) containing impurities into the scrubber device (10) and means (16,17,18) for passing seawater used as scrubbing liquid into the scrubber device (10). At least the scrubbing liquid flowing out of the scrubber device (10) has been fitted to flow into the flotation device (30) for the separation of soot particles, oil and other possible solid impurity particles contained in the scrubbing liquid from the scrubbing liquid.
