Abstract:
1. A method of capturing CO 2 from flue gas emanating from a carbonaceous fuel combusting power plant, which includes a source of oxygen and a combustion chamber for combusting the carbonaceous fuel with oxygen and thereby producing flue gas comprising CO 2 , water and excess oxygen as its main components, the method comprising the steps of: (a) conducting at least a first portion of the flue gas to a first flue gas channel; (b) compressing the first portion of the flue gas for producing a compressed flue gas stream at a pressure less than about one hundred bar; (c) cooling the compressed flue gas stream in a primary CO (d) discharging the first liquid CO (e) conducting the high pressure vent gas stream to a secondary CO
