Definitions
- the present invention concerns a process for capturing CO 2 from exhaust gases from fossil fuel fired power stations, from natural gas streams, from blast furnace oven off-gases in iron/steel plants and from reformer gases containing CO 2 in mixtures with H 2 and CO.
- the invention combines the advantage of precipitating out a solid that contains the bound CO 2 , either as bicarbonate, as an amino-acid- salt/CO 2 complex, or as a complex with limited solubility, formed between an amine and CO 2 , and the use of an activator or promoter to speed up the absorption reaction to an acceptable level.
- a number of patents disclose usage of different types of amines as activators in an alkaline absorbent solution wherein the primary absorbent is an alkaline salt such as potassium carbonate.
- the inclusion of a designated activator such as an amine can yield higher capacity compared to systems where the amine or alkali metal carbonate compound appear alone. See for example, US 2,718,454, 3,144,301 , 3,637,345; 3,793,434;3,848,057; 3,851 ,041 ; 3,856,921 ; 3,896,212; 4,271 ,132 and 4,430,312; BE 767,105; CA 980538 and. ZA 9710745.
- U. S Patent nr 3,896,212 describes the use of a major proportion of alkali metal salts, potassium carbonate and potassium borate, and a minor proportion of a catalytic activator for CO 2 removal from a gaseous stream.
- Belgian Pat. No. 767,105 discloses a process for removing acid gases from gaseous streams by contacting the gaseous streams with a solution comprising potassium carbonate and an amino acid.
- the desorption temperature is elevated, but may possibly be lower than commonly used in amine processes.
- the Alstom Chilled Ammonia process is restricted to ammonium carbonate /bicarbonate and does not utilize a promoter during absorption..
- the process must also be operated at low absorber temperatures leading to difficulties during operation, low capture efficiency due to very slow kinetics at low temperature, as well as energy intensive absorbent cooling.
- the process described in the present invention operates at significantly different temperature than the Alstom process.
- the present invention utilizes an activator or catalyst to increase the rate of absorption even further. Absorption into and precipitation of carbonates is a rather slow process, and thus, deemed less commercially interesting. By using promoters and/or catalysts which are recycled, the absorption rate can be increased significantly.
- the present invention involves a process which is significantly different from the conventional processes and concepts described above, through the utilization of regenerative slurries in conjunction with absorption promoters or catalysts.
- the solid that is formed in the absorber or crystallizer is separated from the solution containing the activator or catalyst where principally only the solid/slurry is conveyed to the regenerator(desorber).
- the promoter or catalyst is thereby separated and does not pass to the regenerator but rather mixed with the lean slurry coming from the regenerator, before it again enters the absorber.
- the present invention provides a method capturing CO 2 from exhaust gas in an absorber (A1), wherein the CO 2 containing gas is passed through an aqueous absorbent slurry wherein said aqueous absorbent slurry comprises an inorganic alkali carbonate, bicarbonate and at least one of an absorption promoter and a catalyst, and wherein the CO 2 is converted to solids by precipitation in the absorber, said slurry having the precipitated solids is conveyed to a separating device (F1), in which the solids are separated off, essentially all the absorption promoter and/or catalyst is recycled together with the remaining aqueous phase to the absorber.
- A1 absorber
- the precipitated solids contain bound CO 2 as bicarbonate, as an amino-acid- salt/CO 2 complex, or a complex with limited solubility, formed by an amine and
- the solids which are separated off form a filter cake. This is sucked dry by utilizing an under-pressure. After dewatering, the filter cake is washed, and the used wash water can be recycled to the absorber.
- Fig. 1 shows a simplified sketch of the slurry CO 2 capture process.
- the CO 2 -containing gas stream, 1, enters the absorber, A1, bottom and flows upwards. It meets a liquid absorbent stream, 3, which is a stream containing a slurry of water, a mixture of the carbonate/bicarbonate of Li, Na, or K, and a promoter or catalyst.
- a liquid absorbent stream 3 is a stream containing a slurry of water, a mixture of the carbonate/bicarbonate of Li, Na, or K, and a promoter or catalyst.
- the aqueous phase is partially or fully saturated with the carbonates and bicarbonates such that the flow contains both solid and liquid.
- the aqueous solution contains an absorption promoter and/or catalyst.
- promoters or catalysts are: piperazine, N-2-hydroxyethylpiperazine, N-(hydroxypropyl)piperazine Diethanol triamine (DETA), 2-((2-aminoethyl)amino)ethanol (AEEA), monoethanolamone (MEA), diethanolamine (DEA), diisopropanolamine (DIPA), methylaminopropylamine (MAPA), 3-aminopropanol (AP), 2,2-dimethyl-1 ,3- propanediamine (DMPDA), 3-amino-1-cyclohexylaminopropane (ACHP), diglycolamine (DGA), 2-amino-2-methylpropanol (AMP), 1-amino-2-propanol (MIPA), 2-methyl-methanolamine (MMEA), piperidine (PE) or mixtures thereof.
- DETA 2-((2-aminoethyl)amino)ethanol

- DEA diethanolamine

- the entering slurry will typically be high in Na 2 CO 3 and low in NaHCO 3 . This implies that the overall Na/CO 2 ratio in the aqueous slurry should be as close to 2 as possible.
- the slurry/solution will contain only carbonate.
- a value of 1 corresponds to full conversion to bicarbonate.
- the bicarbonates of potassium and sodium are less soluble than the carbonates, this will lead to a formation of more solid precipitate in the absorber.
- the precipitating CO 2 bound in the form of an alkali bicarbonate will facilitate a higher loading capacity as it will not contribute to the backpressure of CO 2 over the slurry.
- the slurry leaves the absorber at the bottom, stream 4.
- the promoter and/or catalyst are/is all the time fully dissolved in the aqueous phase and should not adsorb on the solids forming.
- the slurry leaves the absorber at a temperature of 40-90 0 C depending on the inlet gas condition, but typically lower than for a conventional amine process.
- One of the objects of the present invention is to treat the slurry as it evolves in the absorber and to make use of the enhanced absorption capacity, as CO 2 bound in the precipitate will not contribute to the equilibrium backpressure over the solution.
- the absorber can be a traditional type where no solids are formed, and thus, no slurry treatment is necessary, such as a simple packed or structured column.
- the slurry is then passed to a device for solid separation, in figure 1 exemplified as a rotating filter, F1.
- a device for solid separation in figure 1 exemplified as a rotating filter, F1.
- the precipitate forms a filter cake.
- This filter cake is, after its formation, sucked dry by utilizing an under-pressure in a dewatering section of the filter.
- the filter cake is washed on the filter, using the water balance of the process as wash water, stream 17, after which the cake is dewatered again.
- the wash water can be recycled, not shown in figure 1 , and a bleed from the wash water recycle stream is added to the returning slurry stream 5.
- the dewatered solids leave the dewatering operation, F1 , as stream 7.
- the purpose of the dewatering and washing section is to remove all or most of the promoter and/or catalyst from the filter cake so the solid, mainly alkali bicarbonate, can be treated at an elevated temperature without loss or degradation of promoter/catalyst.
- the promoter will only be exposed to the relatively low temperatures of the absorber and a much lower degradation rate than in conventional amine processes is achieved. This opens up for a much wider range of promoters and catalysts than can usually be used in amine processes. The amounts should be so small that they do not adversely affect operation of the process.
- the rotating filter is just used as an example and other separation units are envisaged, such as cyclones, hydrocyclones, all kinds of rotating and stationary filters, and also sedimentation.
- the filter cake should preferably be as dry as possible (low water content), and should contain as little as possible of the promoter.
- the solid/filter cake/thickened slurry, stream 7 is sent to a heat exchanger H1 where it is heated and exits as stream 8. Heat is transferred from the CO 2 -lean slurry, stream 9, returning from the desorber section D1. After heat exchange, the solid/filter cake/thickened slurry, stream 8, is sent to the desorber D1. Here it is heated further to the desired desorber temperature, typically in the range 100-270 0 C.
- the desorber can be a packed tower, a plate tower, a spray tower, a heated conveyor belt, or just a flash tank. The desorber can also be integrated into the heat exchanger.
- the point here is to bring the H 2 O/CO 2 ratio in the vapour mixture leaving the desorber, stream 10, down to the lowest possible value, thereby reducing the stripper steam energy requirement and maximising CO 2 desorption.
- increasing the desorber pressure will make the size considerably smaller.
- the pressure may also be kept low, and even a pressure below atmospheric could be advantageous.
- the water leaving with CO 2 in stream 10 is condensed in the overhead condenser, C1.
- the condensed water, stream 11 can be recycled in three ways. It can be returned to the stripper, D1 , shown by the dashed line in figure 1 , but this is probably the least attractive alternative. It can be mixed with the desorber bottom lean solution, 9, as shown in figure 1 , before going to the heat exchanger H1. Probably the best alternative is to return the condensed water, stream 11 , to the separation stage F1 , with stream 17, as wash water.
- the produced CO 2 leaves the overhead condenser as stream 12 and may have to undergo further cooling, purification
- the promoter and/or catalyst are removed almost quantitatively in the slurry upgrading process such that the desorption process can be run without having to take into account degradation of organic compounds.
- the solids are dewatered such that the water phase in the slurry does not circulate via the desorber, but only with small temperature variations around the absorber.
- the desorber can be operated at a temperature and pressure independent of promoter and/or catalyst properties.
- a high pressure and a low H 2 O/CO 2 ratio in the desorber can be achieved because of the bicarbonate instability.
- the CO 2 can be delivered from the process at a very high pressure, reducing significantly the energy needed for CO 2 recompression.
- the desorber and connected equipment can be smaller because of the higher operating pressure, and this can facilitate absorption from large flue gas streams.
- Desorber operation at sub-atmospheric pressure is possible and can in some cases be advantageous. This necessitates a gas pump on the outlet CO 2 stream,
