Abstract
A method for the treatment of gas generated by the combustion of fossil fuel in a first combustion chamber, the method comprising the steps of transferring the gas to a second combustion chamber, combusting the gas in the second furnace in the presence of oxygen and a fuel source to generate waste gas and treating the waste gas to produce a concentrated carbon dioxide stream.
Claims19
A method for the treatment of gas generated by the combustion of fossil fuel in a first combustion chamber, the method comprising the steps of transferring the gas to a second combustion chamber, combusting the gas in the second combustion chamber in the presence of oxygen and a fuel source to generate waste gas and treating the waste gas to produce a concentrated carbon dioxide stream.
A method according to any one of the preceding claims wherein the second combustion chamber comprises a furnace.
A method according to any one of the preceding claims the fuel source comprises a source of hydrocarbons.
A method according to any one of the preceding claims wherein an operating temperature within the second combustion chamber is higher than an operating temperature within the first combustion chamber.
A method according to any one of the preceding claims wherein at least a portion of the heat generated by combustion of the gas in the second combustion chamber is used to drive one or more electricity generation devices.
A method according to any one of the preceding claims wherein at least a portion of the heat generated by combustion of the gas in the second combustion chamber is directed to the first combustion chamber.
A method according to any one of the preceding claims wherein the waste gas undergoes a separation process to separate certain gaseous components of the waste gas from other gaseous components.
A method according to any one of the preceding claims wherein the concentration of carbon dioxide in the concentrated carbon dioxide stream is greater than 90% v/v.
A method according to any one of the preceding claims wherein the concentrated carbon dioxide stream is collected for sale and/or use.
A method for the treatment of flue gas generated by the combustion of coal in a coal-fired power station, the method comprising the steps of combusting coal in a first furnace, collecting flue gas exiting the first furnace, compressing the flue gas to form a compressed gas, transferring the compressed gas to a second furnace, combusting the compressed gas in the second furnace in the presence of oxygen and a fuel source to generate waste gas and passing the waste gas through one or more separation membranes to produce a concentrated carbon dioxide stream.
