Abstract

SummaryThe present invention is related to an effective and compact method to clean exhaust gases from particulate matter (PM), sulfur- and nitrogen-oxides. A dynamic or semi-dynamic NaS0scrubber with trays covered with rocker valves, is integrated with a Wet Electro-Static Precipitator (WESP) in a combined tower. This type of NaS0scrubber is able of cleaning 75% of the PM and 98% of the SOx and NOx in exhausted gases from diesel engines and e.g. industrial combustion processes. The WESP integrated above the scrubber in the combined tower effectively collects all remaining PM still in the gas after passing through the scrubber, resulting in a simultaneous 98% cleaning of PM, SOx and NOx.
