Abstract
A method of and an apparatus for capturing COfrom flue gas emanating from a carbonaceous fuel combusting power plant, which includes a source of oxygen and a combustion chamber for combusting the fuel with oxygen and thereby producing flue gas that includes CO, water and excess oxygen as its main components. At least a portion of the flue gas is compressed to a pressure higher than about sixty bar, the compressed flue gas is cooled in a primary COseparating unit for capturing a first portion of the COby condensing it to produce a liquid COstream and a high pressure vent gas stream that includes oxygen and excess CO, the liquid COstream is discharged from the power plant, and the high pressure vent gas stream is conducted to a secondary COseparating unit for capturing a second portion of the COby adsorbing it to an adsorbing material.
