Embodiment Construction

[0021] Such as figure 1 shown, used to reduce the carbon dioxide (CO2) present in the flue gas stream 2 ) includes several devices and processes for removing various pollutants from the flue gas stream 120 generated by the combustion of fuel in the furnace 22 . figure 1 The system can be as submitted on September 9, 2009 under the name "ChilledAmmoniaBasedCO 2 CaptureSystemwithWaterWashSystem” (refrigerated ammonia based CO 2 Capture System), as described in US Patent Application No. 12 / 556,043, which is incorporated herein by reference in its entirety. Such as figure 1 As shown, system 100 includes absorption system 130 for absorbing CO from flue gas stream 120 and (in one embodiment) cooled flue gas stream 140 2 .

[0022] Cooled flue gas stream 140 is generated by passing flue gas stream 120 resulting from combustion of fuel in furnace 122 to cooling system 142 . Flue gas stream 120 may undergo a treatment for removing pollutants therefrom, such as a flue gas desulfur...

Abstract

A method for reducing energy requirements of a CO2 capture system comprises: contacting a flue gas stream with a CO2 lean absorbent stream in an absorber, thereby removing CO2 from the flue gas and providing a CO2 rich absorbent stream; heating a first portion of the CO2 rich absorbent stream using heat from the CO2 lean absorbent stream, and providing the heated first portion of the CO2 rich absorbent stream to a regenerator; providing a second portion of the CO2 rich absorbent stream to the regenerator, wherein the heated first portion is hotter than the second portion and the heated first portion is provided to the regenerator at a lower elevation in the regenerator relative to that of the second portion.

Description

[0001] Cross References to Related Applications [0002] The present patent application claims priority to co-pending US Provisional Application No. 61 / 382,205, filed September 13, 2010. technical field [0003] The presently disclosed subject matter relates to methods for removing carbon dioxide (CO2) from flue gas streams. 2 ) systems and methods. More specifically, the presently disclosed subject matter relates to methods for reducing CO 2 Systems and methods for capturing energy requirements of a system. Background technique [0004] During the combustion of fuels such as coal, oil, peat, refuse, etc. in combustion plants such as power plants, a hot process gas, often referred to as flue gas, is produced which contains, among other components, carbon dioxide ( CO 2 ). The negative environmental effects of releasing carbon dioxide into the atmosphere are well known and have led to the development of systems and processes suitable for removing carbon dioxide from the ...
