METHODS AND SYSTEMS FOR REMOVING CONTAMINANTS FROM FLUE GAS ON A SHIP OR OFFSHORE FLOATING VESSEL USING A ROTATING PACKED BED DEVICE

摘要

A method for scrubbing flue gas, comprising: providing a rotating packed bed device onboard a ship or an offshore floating vessel; mixing seawater with the flue gas under centrifugal force in the rotating packed bed device to prevent blow-by and produce a scrubbed flue gas having low sulfur; and discharging the scrubbed flue gas; wherein the scrubbed flue gas has less than half of the sulfur that was originally present in the flue gas before the mixing. Also, a system for scrubbing the flue gas according to the method described. Also, a marine ship, comprising: an engine that combusts HSFO; a rotating packed bed device, in a hull or funnel of the ship, comprising a rotating shaft and a porous material that mixes seawater with flue gas and reduces sulfur in the flue gas; and a connector from the engine and the rotating packed bed device.
