Definitions
- This invention relates to a method and apparatus for removing CO2 and H2O from a gas.
- Metal-organic frameworks are crystalline or non-crystalline, porous metal-organic compounds which have particular pore sizes or pore distributions and large specific surface areas.
- MOFs are known for use in gas adsorption processes. Such processes generally involve the separation of one or more components from a multicomponent gas stream in order to generate a purified gas.
- MOFs particularly those with coordinatively unsaturated metal sites such as the MOF-74/CPO family, have demonstrated extremely high CO2 uptake performance based on pure gas isotherms under equilibrium conditions.
- these MOFs have been found to be unstable under humid conditions. This problem has been considered an irremediable hindrance for their practical use in the purification of gas streams. This is because, in practice, gas mixtures from which CO2 is to be removed often also contain water (H2O).
- MOF-74 analogues when contacted by humid gas streams has been widely reported in the literature.
- the decomposition of the MOF-74 family on contact with moist air or water even at room temperature has been described in detail. This very water-sensitivity has been attributed to material degradation and irreversible decomposition upon water exposure (even at ambient temperature) due to structural changes which ultimately lead to structural collapse.
- MOF-74 analogues have not been considered suitable for most industrial applications of CO2 removal.
- the presence of water vapour has been deemed to reduce the gas adsorption capacity (including of CO2) of these MOFs through the destruction of their structure.
- Several academic articles have analysed the potential mechanism for destruction of MOF-74 materials by water. This has been mainly ascribed to the coordination bonds of MOF-74 compounds, which can be easily attacked by water. Coordinatively unsaturated structures in MOF materials are able to dissociate water molecules. After water dissociation, the open metal site is thought to be occupied by dissociation products which hinder the adsorption of further molecules, such as CO2.
- MOF-74 (and similar types of material) have been considered to lack cyclic stability under real operational conditions. Their use has therefore been relegated only to industrial applications where the materials can be protected from moisture (for example where dehydration processes are considered necessary). Their instability under humid conditions has been considered a severe restriction for practical use in CO2 removal processes. Journal articles where this has been discussed are listed below:
- US5071449A describes general pressure swing adsorption technologies.
- US10239012B2, EP2164607B1 and US9144770B2 relate to pressure swing adsorption processes with various adsorbents.
- US9295939B2 and US10682603B2 describe CO2 removal processes which have a separate water removal step prior to CO2 adsorption.
- Pressure swing adsorption processes with various types of MOF are described in US8142745B2 and EP2089137B1.
- US20140061540A1 relates to pressure swing adsorption processes that utilise MOF-74 materials, but in the absence of water and clearly stated that the stability of the materials need to be further studied.
- this invention relates to a method for removing CO2 and H2O from a gas, the method comprising:

- Metal organic frameworks are generally defined as crystalline or noncrystalline, porous metal-organic compounds, having particular pores or pore distributions and large specific surface areas. Metal organic frameworks have been given various names in the literature, including coordination polymers, metal-organic coordination networks (MOCNs) and porous coordination polymers (PCPs). MOFs generally comprise metal cations and organic bridging groups (or ligands). In MOFs, the organic groups bridge between metal ions so that a polymeric structure results. This polymeric network may extend in one, two or three dimensions. Of particular interest are those structures which extended in two or three dimensions because they may be porous. Specifically, the structures may contain pores which can accommodate other molecules.

- valves V7 and V9 are closed.
- Valve V2, V12 and V16 are opened and valves V3 and V14 remain open.
- Second column 105 thus remains in an adsorption phase.
- the opening of valves V12 and V16 means that the output gas flowing along single output line 65 can flow into valve V16, along output line 32C, through third column output line 30C and into third column 110. This results in the pressurisation of third column 110.
- the opening of valve V2 means that first column 100 is in a blowdown phase in which the adsorbed CO2 and H2O are desorbed from the MOF in first column 100.
- valves V2, V3, V12, V14 and V16 are closed and valves V5, V7, V8 and V15 are opened.
- Third column 110 is in an adsorption phase in this stage.

- the output gas flows along third column output line 30C, through valve V15, further along output line 33C and then into single output line 65.
- the output gas then flows into buffer tank 70 at its input end 70A, and then out from its output end 70B.
- the output gas then proceeds to flow through flow control and flow indicator device 80 after which it may be collected and processed as required.
- the opening of valves V7 and V8 allows pressure equalisation between first column 100 and second column 105.
- valves V7 and V8 are closed.
- Valve V4, V10 and V16 are opened and valves V5 and V15 remain open.
- Third column 110 thus remains in an adsorption phase.
- the opening of valves V10 and V16 means that the output gas flowing along single output line 65 can flow into valve V16, along output line 32A, through first column output line 30A and into first column 100. This results in the pressurisation of first column 100.
- the opening of valve V4 means that second column 105 is in a blowdown phase in which the adsorbed CO2 and H2O are desorbed from the MOF in second column 105.
- the first to sixth stages can then be repeated as required.
