Definitions
- the proposed invention relates to a gas/liquid contacting vessel for treatment of a gas stream, and to a flue gas treatment system for removal of carbon dioxide (CO 2 ) from a flue gas using a liquid absorbent.
- a hot process gas (or flue gas) is generated.
- a flue gas will often contain, among other things, carbon dioxide (CO 2 ).
- the "rich" absorbent containing absorbed CO 2 is subsequently regenerated, whereby absorbed CO 2 is separated from the absorbent, and the regenerated "lean” absorbent is then reused in the CO 2 absorption process.
- a circulating absorbent stream is formed. Regeneration is generally achieved by heating the absorbent in a reboiler to a temperature at which CO 2 is released from the absorbent.
- the chilled ammonia process provides a relatively low cost means for capturing and removing CO 2 from a gas stream, such as, for example, a post combustion flue gas stream.
- a gas stream such as, for example, a post combustion flue gas stream.
- An example of such a system and process has previously been disclosed in the published international patent application WO 2006/022885 titled "Ultra Cleaning of Combustion Gas Including the Removal of CO2".
- the general principle of the chilled ammonia process resembles that of the amine based process described above.
- CCPP combined cycle power plant
- One of the large advantages of CCPP is the operational flexibility, in which the entire load range can be covered within short periods of time. For this reason, CCPP are viewed as a means of complementing the highly variable power output from more unpredictable renewable sources (e.g. wind, solar).
- the flue gas flow rate is a strong function of the gas turbine load, with the value almost halving between 100% and 50% gas turbine load.
- liquid absorbent flow rate can be optimized, resulting in lower liquid absorbent consumption. Also, in systems utilizing regeneration of the liquid absorbent by heating, this in turn leads to reduced regenerator steam consumption when operating the system at partial load.
- the mass transfer device may comprise an absorption column arranged to operate in countercurrent flow mode, wherein the gas stream is fed near a bottom end of the compartment, below the mass transfer device, and a liquid absorbent is fed near a top end of the compartment, above the mass transfer device, such that the gas stream is brought into contact with the liquid absorbent as it rises up through the column.
- the gas stream then leaves the column near the top of the compartment, while the liquid absorbent leaves the column near the bottom of the compartment.
- each gas/liquid contacting compartments 101a, 101 b described with reference to FIG. 1 comprise a single mass transfer device.
- each gas/liquid contacting compartments may also comprise two or more mass transfer devices arranged in series, such that a gas stream fed through the gas inlet first passes through a first mass transfer device and then passes through a second mass transfer device, etc., before being discharged via the gas outlet.
- each gas/liquid contacting compartment may also comprise two or more liquid inlets and, optionally, two or more liquid distribution devices, wherein a first liquid inlet is arranged above the topmost mass transfer device, and a second liquid inlet is arranged between two mass transfer devices.
- Optional outlet valves 1 15, 1 16 prevent gas leaving gas/liquid contacting compartment 101 a from entering gas/liquid contacting compartment 101 b via gas outlet 106b, and/or prevent liquid leaving gas/liquid contacting compartment 101 a from entering gas/liquid contacting compartment 101 b via liquid outlet 1 10b.
- FIG. 2 schematically depicts a regenerator vessel 200, which may for example be employed in an amine based CO2 absorption system, said regenerator vessel having two distinct gas/liquid contacting compartments 201 a and 201 b separated from each other by a substantially vertical partition 202.
- the regenerator vessel 200 of FIG. 2 is similar to the gas/liquid contacting vessel 00 of FIG. 1 , but further comprises a reboiler 220 operative for heating liquid absorbent, collected from the bottom of the two distinct gas/liquid contacting compartments, to generate steam.
- the steam produced in the reboiler 220 may be fed back through gas inlets 204a, 204b to the gas/liquid contacting compartments 201 a, 201 b.
- Each gas/liquid contacting compartment 201 a, 201 b further comprises a mass transfer device 211 a, 2 1 b, arranged between said gas inlet 204a, 204b and said liquid inlet 208a, 208b, and operative for facilitating contact between the steam produced by the reboiler 220 and the CO2 rich liquid absorbent.
- the mass transfer device 21 1a, 21 1 b may, e.g., comprise one or more commonly known structured or random packing materials, or a combination thereof, provided in the form of an absorption column, such as a packed bed column.
- the mass transfer device may preferably be arranged to operate in countercurrent flow mode.
- the mass transfer device may comprise an absorption column arranged to operate in countercurrent flow mode, wherein the steam from the reboiler is fed near a bottom end of the compartment, below the mass transfer device, and the CO2 rich liquid absorbent is fed near a top end of the compartment, above the mass transfer device, such that the steam is brought into contact with the liquid absorbent as it rises up through the column.
- the vessel comprises shut-off means, whereby gas and/or liquid flow to one of the a gas/liquid contacting compartments can be blocked independently of the other of said compartments.
- the gas/liquid contacting vessel 200 comprises a system of fluid valves that enables the liquid and/or gas supply to one of the gas/liquid contacting compartments to be opened or closed.
- the system comprises inlet valves 213, 214 and optionally also outlet valves 215, 216.
- both inlet valves 213, 214 are closed, the entire gas stream coming from the gas duct 205 is directed to the gas inlet 204a of gas/liquid contacting compartment 201a, and the entire liquid stream coming from liquid absorbent supply duct 209 is directed to the liquid inlet 208a of gas/liquid contacting compartment 201a.
- both inlet valves 213, 214 are open, the gas stream and the liquid stream are instead distributed, e.g.
- Optional outlet valves 215, 216 prevent gas leaving gas/liquid contacting compartment 201a from entering gas/liquid contacting compartment 201 b via gas outlet 206b, and/or prevent liquid leaving gas/liquid contacting compartment 201a from entering gas/liquid contacting compartment 201 b via liquid outlet 210b.
- FIG. 3b represents a gas/liquid contacting vessel having four gas/liquid contacting compartments, a-d, each defined by an inside wall of the vessel and a two substantially vertical walls extending throughout two different substantially vertical cross-section planes of the inner volume of the vessel.
- the four compartments a-d may preferably be volumetrically equal, but can also be volumetrically different.
- each of the absorber vessel 100 and the regenerator vessel 200 of an absorption based carbon dioxide (CO2) capture system comprise gas/liquid contacting vessels having at least two distinct gas/liquid contacting compartments
- the absorber vessel and the regenerator vessel may preferably have the same number of gas/liquid contacting compartments.
- the capacity of the flue gas treatment system can be adjusted according to the mass flow rate of the incoming flue gas to be treated. This allows for the ratio of flow rate to residence time (liquid-to-gas ratio) to be maintained closer to a predetermined value than possible with conventional single compartment vessels. This means the operation can be conducted closer to the design point and that CO2 capture efficiency can be kept high across a larger load range. Furthermore, the liquid absorbent flow rate can be optimized, which in turn leads to reduced regenerator steam consumption when operating the system at partial load.
