    Adsorption device for compressed gas.
    The present invention relates to an adsorption device for compressed gas, for example compressed air.
    More specifically, the invention relates to an adsorption device for compressed gas, which adsorption device comprises a vessel in which an adsorbent, for example a desiccant, or so-called desiccant, is arranged. The vessel in question is provided with an inlet for supplying a treated, compressed gas, and with an outlet for discharging treated gas.
    The adsorbent in question is usually in the form of a regenerable adsorbent, or in other words an adsorbent that can be regenerated, after a certain degree of saturation has been achieved. For the sake of simplicity, an adsorbent in the form of a desiccant is generally referred to below, but the invention also extends to other adsorbents. For example, in the case of a drying device, it is true that, as the adsorbent, which is then in the form of a drying agent, extracts moisture from the gas to be dried, this drying agent will become more and more saturated with adsorbed moisture. It is therefore common, after using the desiccant for a certain time to dry compressed gas, to regenerate this desiccant, for example, by exposing it to a regeneration gas stream that extracts moisture from the desiccant. Such a regeneration gas stream may, for example, consist of a fraction of the dried gas and / or hot gas the relative humidity of which is sufficiently low to enable the regeneration of the drying agent to be obtained.
    In some embodiments of compressed gas dryer, two or more barrels of desiccant are used. In the case of two vessels, this drying device principle is also referred to as a 'twin tower' dryer. In such a type of drying device, for example, a compressed gas, for example from a compressor, can pass through a first of the aftercoolers after passing through an aftercooler and an condensate screener (which may or may not be part of the aftercooler in question). said vessels are fed where it will be dried by the drying agent present in that particular vessel. This vessel therefore acts as a drying vessel.
    At the same time, a regeneration gas stream can be passed through a second aforementioned vessel in order to regenerate the drying agent present in that second vessel by extracting the moisture from this drying agent. This can be done, for example, by using an already dried gas that is branched downstream of the drying vessel and / or by supplying a gas stream that is heated, for example, by recovering the heat generated during compression in the compressor. In the latter case, a "heat-of-compression" or HOC dryer is used. Of course, other known regeneration principles can also be applied.
    When the desiccant in the drying vessel has reached a certain degree of saturation, the gas flows through the first and the second vessel can be exchanged, such that the desiccant in the first vessel will now be regenerated by a regeneration gas stream, while the second vessel will take on the task of drying vessel. For example, the two or more vessels will function alternately as a drying and as a regenerating pressure vessel, such that a continuity in the drying process can be achieved. Examples of such drying devices with multiple vessels are described, for example, in US 2003 / 023,941, US 4,783,432, US 6,375,722, EP 1,776,171 and WO 2006 / 050,582.
    The desiccant used in such multi-vessel adsorption devices often consists of granules of silica gel, "activated alumina" or "molecular sieve" material, or a combination thereof. As is known, activated alumina is produced by thermal dehydration or activation of aluminum trihydrate, Al (OH) 3, while molecular sieves consist of synthetic zeolites (crystalline aluminosilicates).
    A limitation of such a type of drier that includes granular desiccant agent consists in that the gas velocities through the vessels must remain limited in order to prevent granules moving or even fluidization opposing each other. After all, as a result of the granules moving, friction will occur between them, which in turn leads to dust formation and a reduced drying capacity. Still other causes of such dust formation are, for example, pressure variations and / or thermal shocks. In addition, the pressure drop over a 'twin tower' dryer is relatively large and the desiccant grains have a relatively high thermal mass.
    Alternatively, drying devices are known for compressed gas, wherein the drying agent is arranged in a rotating drum, while a drying zone and a regeneration zone extend in the vessel. During the operation of such a drying device, the drying drum will be made to rotate by means provided for this purpose, so that the drying agent in this drying drum will be alternately passed through the drying zone and the regeneration zone. The compressed gas to be dried will be passed through the drying zone, while the regeneration gas stream is passed through the regeneration zone, so as to enable simultaneous drying of compressed gas in the drying zone and regeneration of drying agent in the regeneration zone.
    Examples of such drying devices which are provided with a rotary drying drum are described, for example, in WO 00 / 033,943, WO 00 / 074,819, WO 01 / 078,872, WO 01 / 087,463, WO 02 / 038,251, WO 2007/079533, WO 2005 / 070,518, WO 2006 / 012,711, GB 1,226,348, GB 1,349,732, GB 1,426,292, US 3,490,201, US 5,385,603 and US 8,349,054.
    The desiccant or desiccant used in the known compressed gas drying devices includes, for example, silica gel, molecular sieves, activated alumina or a combination thereof. The desiccant can, as is known, be applied to a support such as a corrugated structure of glass fibers or ceramic fibers which is, for example, rolled up to form a honeycomb structure in the vessel, for example as described in US 5,683,532. In practice it appears that the known drying devices for drying compressed gas, under certain circumstances, such as in the case of insufficient regeneration of the drying agent and in the case of over-saturation thereof, the drying agent goes through a complex weathering process which, in some cases, may ultimately result in a failure of the drying device, for example, in the case of silica gel as a drying agent in a rotor, because the binder function of the silica gel decreases, which leads to loss of structural strength of the supporting glass fiber matrix, and because also the adsorbent function of the silica gel decreases as a result of hydrolization and degradation of the silica gel structure.
    For example, the adsorption behavior and the adsorption capacity of a silica gel rotor, under severe conditions of high humidity and high temperature, will change considerably during the life of the rotor.
    The present invention has for its object to provide a compressed gas adsorption device which offers a solution to one or more of the disadvantages associated with the conventional, already known adsorption devices using an adsorbent.
    To this end the invention relates to an adsorption device for compressed gas, which adsorption device is provided with a vessel with an inlet for supplying a treated, compressed gas, and an outlet for treated gas and wherein in said vessel an adsorption device element, which adsorption element extends between said inlet and outlet in the direction of flow of the compressed gas to be treated and, according to the invention, consists of a monolithic support structure which is at least partially provided with a coating which an adsorbent.
    An advantage of such an adsorption device according to the invention is that there is no risk of movement or fluidization, since no loose granules of adsorbent are used. This avoids dust formation, while still allowing a relatively high flow rate of the compressed gas to be treated through the adsorber.
    Moreover, such an adsorption device according to the invention allows the vessel to be placed upright, obliquely or even horizontally, during use, which is not possible, for example, with conventional drying devices using granular desiccant, since the horizontal use of such known drying devices can lead to a rearrangement of the granules and the formation of internal leakage paths and, therefore, a reduced dryer performance.
    According to a preferred feature of the invention, the aforementioned monolithic support structure comprises one or more of the following materials: ceramic material, metal foil, a fiber structure and a polymer. Particularly good results are obtained with the use of a ceramic structure comprising cordierite.
    Preferably, the aforementioned adsorbent comprises one or more of the following materials: a zeolite, silica gel, activated alumina, activated carbon, metal-organic frameworks, carbon molecular sieve (CMS) , an impregnated adsorbent and a hybrid adsorbent. A hydrophilic zeolite is particularly preferred. Good results are obtained by using faujasite or zeolite type X, the silicon / aluminum ratio of which is between 2 and 3.
    According to a special embodiment of the invention, the adsorption device in the aforementioned vessel comprises a plurality of adsorption elements arranged in series in the direction of flow of the gas.
    The present invention also relates to an adsorption element for a compressed gas adsorption device, which adsorption element comprises a monolithic support structure that is at least partially provided with a coating comprising an adsorbent.
    In addition, the invention also relates to a pattern comprising a stack of adsorption elements which are provided with a monolithic support structure which is at least partially provided with a coating comprising an adsorbent.
    With the insight to better demonstrate the characteristics of the present invention, a few preferred embodiments of an adsorption device according to the invention are described below, as an example without any limiting character, with reference to the accompanying figures, in which: figure 1 schematically shows an adsorption device according to the invention; Figure 2 shows a pattern of adsorption elements according to the invention; figure 3 shows on a larger scale the part which is indicated by F3 in figure 2; figure 4 represents a variant of an adsorption device according to figure 1; figure 5 represents a variant of figure 3, in the mounted state of the stack of adsorption elements in a vessel; and Figure 6 shows a detail of the top edge of a stack of adsorption elements in the mounted state in a vessel.
    Figure 1 schematically shows a possible embodiment of an adsorption device 1 according to the invention, which in this case forms a drying device and which comprises two vessels 2A and 2B which are each provided with an inlet 3A and 3B for supplying a treat (to be dried in this case), compressed gas, and from an outlet 4A or 4B, respectively, for the discharge of treated (in this case dried), compressed gas.
    The respective outlets 4A and 4B are connected via outlet lines 5A and 5B to a pressure line 5 of a compressor 6, in this example a compressed air compressor. Each of the outlet pipes 5A and 5B can be closed by means of an outlet valve 7A and 7B provided for this purpose.
    On each outlet line 5A and 5B, between the respective outlet valve 7A and 7B, on the one hand, and the respective outlet 4A and 4B, a connection is provided with a discharge line, 8A, and 8B, respectively, which can be connected by means of a respective discharge valve 9A and 9B which, in this case, but not necessarily, is connected to a common outlet 10.
    The aforementioned inlets 3A and 3B are connected to each other by means of a connecting line 11 in which a first set of two shut-off valves 12A and 12B placed in series is provided. The relevant valves 12A and 12B are bridged by a bypass line 13 in which a second set of two shut-off valves 14A and 14B placed in series is arranged.
    The connecting line 11 and the bypass line 13 are interconnected by means of a cooling line 15, in which a heat exchanger 16 and a condensate separator 17 are arranged. One end of the cooling line 15 connects to the connecting line 11, between the first set of shut-off valves 12A and 12B, while the other end of the cooling line 15 connects to the bypass line 13, between the second set of shut-off valves 14A and 14B.
    In this example, each of the outlet valves 7A and 7B, the discharge valves 9Δ and 9B and the shut-off valves 12A, 12B, 14A and 14B is designed in the form of a controllable valve which is connected to a control unit 18, or via control lines provided for that purpose. for clarity are not included in the figure either wirelessly.
    In each of the aforementioned vessels 2A and 2B an adsorption element 19A and 19B is arranged according to the invention, in this case in the form of drying elements, in particular in the flow trajectory of the gas to be dried, or in other words according to the direction of flow of the compressed gas to be treated, between the aforementioned inlet 3A and 3B, on the one hand, and the aforementioned outlet 4A and 4B, on the other hand.
    As for the first vessel 2A, the adsorption element 19A will extend with an inlet side 20A opposite the aforementioned inlet 3A, while an outlet side 21A of the adsorption element 19A will extend opposite the outlet 4A.
    Analogously, the adsorption element 19B in the second vessel 2B has an inlet side 20B and an outlet side 21B which extend opposite the inlet 3B and the outlet 4B, respectively.
    According to the invention, the adsorption elements 19A and 19B comprise a monolithic support structure which preferably, but not necessarily, consists of a ceramic structure comprising cordorite, for example Celcor® from Corning. Alternatively, according to the invention, other materials can also be used for the manufacture of the relevant support structure such as: - other ceramic materials such as mullite, γ- or α-alumina or silicon carbide (SiC); - metal foil; or a fiber structure, for example based on glass fiber, ceramic fiber or other fibers, or a mixture of different types of fibers; or - a polymer.
    Naturally, the aforementioned list is not restrictive and the use of other materials is not excluded.
    According to the invention, it is also not excluded that the monolithic support structure is made from a combination of two or more of the aforementioned and / or other materials.
    The material of the support structure preferably contains between 200 and 1200 CPSI ('cells per square inch'), and more preferably between 350 and 450 CPSI.
    The wall thickness of the support structure is preferably between 2 and 11 mils (milli-inch), and more preferably between 3 and 9 mils and even more preferably between 5 and 7.5 mils. In a most preferred embodiment, the wall thickness is between 6 and 7 mils, preferably almost 6.5 mils.
    The porosity of the wall of the support structure is preferably greater than 5%, and more preferably greater than 10%, but, even better, greater than 20%.
    The cells formed preferably have a square shape, but may have other shapes such as triangular, sinusoidal, circular, hexagonal and the like.
    According to the invention, the aforementioned monolithic support structure is at least partially provided with a coating comprising an adsorbent.
    According to the invention, the adsorbent in question can comprise one or more of the following and / or other materials: - a zeolite, preferably a hydrophilic zeolite, but also a hydrophobic zeolite is possible - this zeolite can, for example, faujasite zeolite type X, for example Zeolum F9 from Tosoh, or a mixture of zeolite type X and A; - silica gel; - activated alumina; - activated carbon ('activated carbon'); metal-organic grids ('metal-organic frameworks'); - carbon molecular sieve (CMS); - an impregnated adsorbent; and a hybrid adsorbent.
    The foregoing list is not limitative, but other materials are also possible according to the invention.
    The choice of the adsorbent depends on which treatment is to be given to the gas to be treated, such as drying or removing other molecules such as oxygen and carbon dioxide, for example when the adsorber is operating as a nitrogen generator, the compressed gas to be treated being compressed air is.
    The particle size distribution of the adsorbent is preferably such that D 50 is less than 10 µm and more preferably less than 4 µm.
    The aforementioned coating preferably comprises, in addition to the aforementioned adsorbent, also a binder material, preferably an inorganic binder material such as: colloidal silica, for example Ludox-AS 40 from Grace Davison; alumina; and / or clay.
    In addition, optionally use can also be made of an organic binder material such as: methyl cellulose; polymers such as acrylic resins, vinyl resins and the like; and / or - a material from the cellulose group.
    In the illustrated example of Figure 1, each vessel 2A and 2B contains a single adsorption element 19A and 19B, respectively, but the invention is not limited as such, since, according to a variant of an adsorption device 1 according to the invention, as shown in figure 2, in a vessel 2A and / or 2B, two or more adsorption elements 19A or 19B, arranged in series with the flow direction of the gas, can also be provided. Figure 2 shows an example of several adsorption elements 19A stacked on top of each other, which in this example are of disc-shaped design and all have a flat bottom and top surface.
    Preferably, a seal 22 is provided between two adsorption elements 19A stacked on top of each other over the peripheral edge of these adsorption elements 19A, in this case an annular seal which is provided with at least one radially inwardly directed lip, and in this case with two radially inwardly directed, V-shaped lips 23 extend between the interfaces of the stacked adsorption elements 19A.
    A shrink sleeve 24 is preferably provided over the circumferential wall of the entire stack of adsorption elements, preferably from an elastic material which is low in gas, for example polyolefin. The shrink sleeve 24 in question can also be arranged only over a part of the height of the stack of adsorption elements.
    The whole of stacked adsorption elements 19Ά thus forms a pattern which is interchangeable or replaceable according to a particular aspect of the invention.
    The operation of an adsorption device 1 according to the invention is very simple and as follows.
    Initially in this example, the first vessel 2A will perform the function of drying vessel, while. the adsorption element 19B (which is therefore a drying element here) in the second vessel 2B will be regenerated.
    The compressor 6 draws in a gas, for example ambient air, and compresses this gas. The compressed, hot gas is then passed, via the pressure line 5, through the outlet line 5B, via the opened outlet valve 7B, to the outlet 4B of the second vessel 2B.
    The hot compressed gas will have a sufficiently low relative humidity to extract moisture from the drying agent present in the adsorption element 19B and thus to regenerate this adsorption element 19B. In other words, the desiccant is dried in the second vessel 2B.
    The warm, moist gas is then sent via opened shut-off valve 14B to the cooling line 15, where it is successively passed through the heat exchanger 16 and the condensate screen 17, and then through the opened shut-off valve 12Ά and the connecting line 11 to the inlet 3A of the first vessel 2A to be fed.
    The cold, compressed gas that is 100% saturated will enter the first vessel 2A, via the inlet 3A, and be passed through the adsorption element 19A.
    The adsorbent present on the support structure will extract moisture from the gas during the flow of the compressed gas through the adsorption element 19A. The adsorbent will therefore play the role of desiccant or desiccant material in this example.
    The gas leaving the adsorption element 19A on its outlet side 21A will be drier than the gas entering the vessel 2A via the inlet 3A.
    The dried, compressed gas then flows, via the outlet 4A and through the outlet line 5A and the opened discharge valve valve 9A, to the discharge line 8A and to the outlet 10 coupled thereto, which can be connected to a consumer of dried, compressed gas.
    After a certain cycle time, the operation of both vessels 2A and 2B can be exchanged in known ways and the second vessel 2B can take on the role of drying vessel, while the desiccant can be regenerated in the first vessel 2A.
    Due to the fact that the adsorption device 1 according to the invention does not use granular desiccant, the vessels 2A and 2B can be placed in any position such as vertical, horizontal or any other position.
    Since the adsorbent is adhered to a supporting structure, there is no risk of fluidization, such as with granular desiccant, and therefore dust formation cannot occur even at high gas velocities through the adsorption element.
    When using several superimposed adsorption elements 19A as shown in Figure 2, the gas, either as a gas to be dried or as a regeneration gas, will flow sequentially through the successive adsorption elements.
    The presence of the aforementioned seals 22 between successive adsorption elements 19A prevents leaks from occurring between the side wall of the stack of adsorption elements 19A on the one hand, and the inner wall of the vessel 2A on the other. The same applies to the use of such a stacking of several adsorption elements 19B in the second vessel 2B, which of course is also possible and can also be provided with the said seals 22.
    Figure 4 shows another embodiment of an adsorption device 1 according to the invention, wherein in this case there is only one vessel 25 in which an adsorption element 19 is rotatably arranged. The adsorption element 19 is connected to drive means, for example in the form of an electric motor 26.
    As with known rotary drum dryers, a regeneration zone and an adsorption zone (in this case a drying zone) extend in the vessel. The pressure line 5, in this case coming from a compressor 6, connects, as with known HOC dryers, to the inlet of the regeneration zone. The outlet of the regeneration zone is, in a known manner, connected via a connecting line 27 to the inlet of the adsorption zone. A heat exchanger 16 and condensate screen 17 are provided in the respective connecting line 27.
    The outlet of the regeneration zone is finally connected to the outlet 10 via a discharge line 8.
    The operation of an adsorption device 1 according to Figure 4 is analogous to that of known HOC dryers with a rotating drum in which drying agent is provided. However, because of the structure of the adsorption element 19, such improved adsorption device according to the invention is not susceptible to failure due to a reduction in bearing capacity. After all, the monolithic support structure of an adsorption element in an adsorption device of the invention does not lose the structural strength, even under severe conditions of high humidity and high temperature.
    The embodiments of adsorption device 1 according to the invention shown in the figures both relate to full-flow HOC dryers, however, the invention is not limited as such, since an adsorption device 1 according to the invention does not necessarily have to follow a flow-flow principle to work. It is also not required according to the invention for the compression heat to be used for the regeneration of the adsorbent, but use can be made of any regeneration gas that may or may not come from the process itself and that may or may not be compressed gas.
    Figure 5 shows a variant of the detail of claim 3, wherein in this case the stack of adsorption elements 19A is arranged in the vessel 2A and a part of the wall of this vessel 2A is visible.
    The seal 22 in this example comprises a ring 28, for example, but not necessarily, made of aluminum, another metal or a polymer, the inner diameter of this ring 28 being slightly larger than the outer diameter of the adsorption elements 19A, which in this case for example, be disk-shaped.
    The ring 28 extends over the peripheral edge of the superposed ends of the adsorption elements 19A. On its inner circumference the relevant ring 28 is provided with an inwardly directed, radial edge 29 against which the respective ends of the adsorption elements are arranged.
    In order to obtain a good seal and to prevent leakage paths, a sealing layer 30 and 31 are provided on either side of the relevant edge 29 over the entire circumference, for example in the form of a quantity of glue or of another sealing element.
    Across its outer circumference, the ring 28 in this example is provided with two substantially parallel ribs 32 spaced apart axially, between which a seal 33, in this case in the form of an O-ring, is provided. The presence of the ribs 32 is not a strict necessity according to the invention. Thus, for example, only one rib on which the seal 33 rests can be provided, or the seal can be fixedly mounted on the ring 28 or form an integral part thereof.
    When mounting the cartridge consisting of superimposed adsorption elements, as shown in Figure 5, the seal 33 will press against the inner wall of the vessel 2A. In this way it is ensured by means of this construction that leaks are avoided not only between the adsorption elements 19A themselves, but also between the cartridge and the wall of the vessel.
    Again, it is clear that the particular embodiment is not limited to use in vessel 2A, but it can also be used in vessel 2B of Fig. 1 and / or in vessel 25 of Fig. 4, or in any other type of adsorption. device 1 according to the invention.
    Figure 6 shows a detail of an upper edge of an upper of a stack of adsorption elements 19A in mounted condition in a vessel 2A. The wall of the vessel 2A is shown on the right in the drawing. The same construction is possible at the bottom edge of a stack of adsorption elements or, if only one adsorption element is used in a vessel, at the top and / or bottom of such a separate adsorption element.
    A V-shaped seal 34 is slid over the free peripheral edge of the adsorption element 19A, in other words the peripheral edge that is not directed towards another adsorption element 19A, such that a first leg 35 of the seal is against presses the axial upper surface 36 of the adsorption element 19A, while the second leg 37 of this seal 34 presses against the radial outer wall 38 of the adsorption element 19A.
    The V-shaped seal 34 in this case has a lobe-shaped protrusion 39 on top, or in other words on the side where the two legs 35 and 38 are connected to each other.
    According to a preferred feature of the invention, pressing means are provided which press a portion of the seal 34 radially against the inner wall of the vessel 2A. In this example, the respective pressing means comprise a conical ring 40, which is pressed against the lobe-shaped protrusion 39 of the seal 34 by means of a spring 41. For this purpose, the conical ring 40 is directed with its conical surface towards the respective seal 34 and the spring with its other end presses, for example, against the lid of the vessel 2A. It goes without saying that the portion of the seal 34 pressed against the inner wall of the vessel 2A should not necessarily be lob-shaped, but that this portion can be designed in many different ways.
    The largest outer diameter of the conical ring 40 is preferably, but not necessarily, substantially as large as the inner diameter of the vessel 2A.
    As an alternative to the construction as shown by way of example in Fig. 6, the seal on the top and bottom of the cartridge consisting of a stack of adsorption elements 19A can be obtained in other ways, for example by using a glued ring and an O-ring, similar to the principle as shown in figure 5.
    Although the above description primarily describes an adsorption device in the form of a moisture adsorbent, the invention also relates to other types of adsorption devices such as nitrogen generators and the like, whose adsorption element is capable of gas molecules such as oxygen, carbon dioxide and / or the like. After all, as known, nitrogen can be generated by removing such gas molecules from, for example, compressed air.
    The present invention is by no means limited to the embodiments described by way of example and shown in the figures, but an adsorption device according to the invention for compressed gas can be designed in many shapes and dimensions without departing from the scope of the invention.
