Abstract
A method for scrubbing flue gas, comprising: providing a rotating packed bed device onboard a ship or marine vessel generating flue gas; co-feeding an absorbent with the flue gas into the rotating packed bed to remove carbon dioxide.
Claims6
A method for removing carbon dioxide from a flue gas, on a ship or marine vessel generating flue gas comprising:
- (a) feeding CO2 containing flue gas to a Venturi Quencher to treat the hot flue gas from a ship and cool it down, (b) feeding the cooled flue gas into a rotating packed bed (RPB) device and (c) contacting with a scrubbing fluid to form a spent fluid with bound CO2.
An integrated system for onboard scrubbing of a marine exhaust gas on a ship, comprising:
- i) a hot exhaust gas entry that feeds the marine exhaust gas, having a temperature greater than 180° C., from an engine on the ship;
- and b) the rotating packed bed device, having:
- iii) a stationary gas distributor, placed along an outer circumference of the rotating packed bed device, connected to a Venturi quencher, wherein the stationary gas distributor is configured to receive the cooled exhaust gas and uniformly distribute the quenched marine exhaust gas along the outer circumference of the rotating packed bed device;
- and
- iv) a stationary liquid distributor, with multiple liquid rings, that is centrally positioned within the rotating packed bed device, wherein the multiple liquid rings are fitted with spray nozzles that spray a liquid absorbent as a co-feed with the cooled exhaust gas into the annulus of the rotating packed bed device.
