Abstract

A system (10) for scrubbing exhaust gases from an engine, particularly from a marine engine, comprises a quenching chamber (22) of a high temperature resistant material, the quenching chamber containing nozzles (30) for spraying water droplets into the exhaust gases; a scrubbing duct (24) of sufficient length and cross- sectional area that the residence time for exhaust gases in the scrubbing duct is greater than 2 seconds, the scrubbing duct (24) comprising nozzles (32) for spraying water droplets so that water droplets fall through the flowing exhaust gases; and a demister unit (26) at the downstream end of the scrubbing duct (24). The system (10) can be set up to provide a substantially horizontal flow path for the exhaust gases in which the water droplets pass across the gas flow. The system (10) can be retrofitted to a ship, and does not impose a significant back pressure on the exhaust gases.
