Definitions
- This invention relates generally to the recovery of carbon dioxide from flue gases generated by industrial processes, for example coal-fired power plants, steel plants, smelters, cement kilns and calciners.
- Post-combustion capture is already practised for producing CO 2 from combustion gases for a range of high value uses (eg. food additives or for enhanced oil recovery).
- the process involves:
- the invention accordingly provides, in a first aspect, a method of recovering carbon dioxide from a stream of flue gases, comprising:- cooling the stream of flue gases to a temperature suitable for efficient absorption of CO 2 from the stream by a predetermined sorbent system;
- the invention also provides in the first aspect an apparatus for recovering carbon dioxide from a stream of flue gases, comprising:
- sorbent regeneration means for desorbing CO 2 from the CO 2 -rich absorbent stream by application of heat to the absorbent stream to desorb the CO 2 ;
- the apparatus further includes a first heat exchange zone for recovering energy released by said cooling means and from which the recovered energy is carried by an intermediate fluid.
- means are included for recycling CO 2 -lean sorbent produced by said sorbent regeneration means.
- Heat exchange means may be provided for subjecting the recycled CO 2 -lean sorbent to heat exchange with the CO 2 -rich sorbent for cooling the sorbent to the temperature of the cooled flue gases in the CO 2 absorption.
- means are provided for compressing, cooling, and liquefying CO 2 desorbed from the CO 2 -rich absorbent stream for storage.
- the apparatus includes means for recycling energy released by this step to the aforesaid CO 2 desorbing step.
- the plant utilises a heat pump system including one or more heat exchange stages for effecting said energy recovery in an integrated fashion.
- the invention further provides a plant energy management system that takes advantage of the improved energy efficiency of post-combustion capture of CO 2 enabled by the method and apparatus described above.
- the invention accordingly provides a plant energy management system including: selectively recovering carbon dioxide from a stream of flue gases in accordance with the first aspect of the invention;
- said selective recovery includes relatively reduced recovery of carbon dioxide during periods of high energy demand to maximise power generation by the plant, and relatively increased recovery of dioxide at other times.
- the predetermined limit of carbon dioxide emissions is a total or averaged limit over a prescribed time period, such that selected said periods of relatively reduced recovery of carbon dioxide do not cause the relevant limit to be exceeded.
- FIG. 2 is a diagram of energy transfers in accordance with an embodiment of the invention.
- Figure 3 is a diagram of percentage capture of CO 2 from a flue gas in the CO 2 absorption stage of post combustion capture, as a function of the temperature to which the flue gases are cooled before contacting the absorbent system.
- FIG. 1 depicts the essentials of a coal-fired electricity generation power plant 10.
- Coal and air are delivered to a large scale boiler system 12 which heats large volumes of water to generate steam 14 for driving a steam turbine 16.
- Turbine 16 in turn powers a generator 18 that produces electricity as its output.
- the steam recovered from turbine 16 passes through a condenser 22 for recycling to the boiler and release into the atmosphere via a cooling tower 24.
- the amount of regeneration, and therefore the amount of capture, that can be obtained will depend on several factors including the moisture content of the flue gases, the energy and temperature required for the desorber, and the efficiency of the heat pump system. These factors will also directly affect the parasitic power requirements for the heat pump.
