A system for removing contaminants from exhaust gas emitted by a marine combustion engine, the system comprises an exhaust gas inlet 4 and an exhaust gas outlet 7, between the them is a quenching section 6 for mixing the exhaust gas stream with a quenching liquid stream and a scrubbing section 8 downstream of the quenching section for mixing the exhaust gas stream with a scrubbing liquid stream to remove liquid soluble contaminants from the exhaust gas, where the quenching system comprises a packed region 16 comprising packing material through which the exhaust gas and quenching liquid streams pass before entering the scrubbing section. The quenching section may comprise a nozzle 14 for providing the quenching liquid, a curved inlet 18 and a flow restriction 19 upstream of the packing material. The scrubbing section preferably comprises multiple of sub-regions 26 28 30 32, where each region has structured packing material with fluid passageways. After the scrubbing section there may be a sump 34 to collect liquid and a demister 38 to remove moisture from the gas. The quenching and scrubbing liquid may be sea water. |
