Definitions
- Adsorber comprising parallel passage contactors with integrated insulation
- the invention relates to the isolation of an adsorber comprising several parallel-passage contactors and to the use of this same adsorber.
- Adsorption is a physical phenomenon that is increasingly used industrially to separate or purify gas flows.
- adsorption is conventionally used to dry various gas streams, in particular air, natural gas, for the production of hydrogen, for the production of oxygen and / or nitrogen from air atmospheric, to capture many components of various effluents before their use in a downstream process or venting such as VOC, nitrogen oxides, mercury ...
- the present invention will particularly relate to TSA.
- the adsorbent used is generally in the form of particles filled with an adsorber. These particles can be in the form of granules, rods, balls, crushed. The characteristic dimensions of these particles generally range from 0.5 mm to 5 mm.
- Axial cylinders of conventional adsorbents in the form of balls use thermal insulation between the beds of balls and the ambient.
- thermal insulation between the beds of balls and the ambient.
- a small bottle typically with a diameter of less than 2 m, it is rather used an external insulation reported on the outer shell of the bottle, type insulation glass wool, or cellular glass or polyurethane foam: this insulation remains inefficient because during the heating phase in regeneration of the bottle, a portion of the thermal energy is used to heat the metal of the bottle, requiring the heat loss to be compensated by over-sizing the regeneration flow rate.
- an internal insulation On a large bottle, typically with a diameter greater than 2m, an internal insulation is used: it must mechanically be able to contain the beds of adsorbent beads, not to favor the creation of preferential gas passage (outside the adsorbent bed) and be able to withstand any compression / decompression cycles between adsorption and regeneration.
- a system of single or double gas blades which serves as an insulating cushion is conventionally used, considering that the air space remains stationary. These blades, relatively efficient in terms of insulation, are difficult to implement and cost relatively expensive.
- a solution of the invention is an adsorber for adsorption of a fluid, comprising a bottle with at least two parallel-passage contactors arranged in series in the direction of the path of the fluid to be adsorbed, and characterized in that each contactor comprises an insulation internal.
- internal insulation is meant an insulation which is specific to each contactor with parallel passages; in other words integrated in each contactor.
- Parallel passage contactor means a device in which the fluid passes through channels whose walls contain adsorbent.
- the fluid circulates in essentially obstacle free channels, these channels allowing the fluid to flow from an input to an output of the contactor.
- These channels can be rectilinear connecting directly the input to the output of the contactor or present changes of direction.
- the fluid is in contact with at least one adsorbent present at said walls.
- the parallel-channel contactors have less pressure losses, which allows loss of equivalent charges to reduce the diameter of the adsorber, possibly increasing its height.
- the contactors with parallel passages of the adsorber according to the invention may comprise one or the other of the following internal isolations.
- the internal insulation of each of the contactors comprises:
- Watertight means that prevents the creation of preferential gas passage outside the contactor with parallel passages.
- Figure 1 shows a contactor with parallel passages with the double environment.
- Figure 2 shows an adsorber according to the invention comprising a series of contactors with parallel passages with the double environment.
- the insulation is preferably chosen from perlite, glass wool, rockwool, cellular glass, vacuum, airgel, multilayer insulation or any other insulation or combination of insulators conventionally used. artwork...
- this first alternative can be supplemented by sealing elements fixed on the outer shell of the double environment facing the inner ferrule of the bottle.
- the sealing elements are preferably selected from brushes, seals, welds or welded elements, glue or glued elements and preferably sized to overcome the possible differential expansion between the shell of the adsorber and the double environment of the parallel passage contactors during regeneration of the adsorber.
- each parallel-channel contactor has channels and the channels are at least partly obstructed over a centripetal radial distance of 20 cm, preferably 10 cm, even more preferably 5 cm starting from the outer perimeter of the parallel-path contactor. .
- This obstruction prevents the creation of preferential gas passage in the channels concerned.
- the parallel passage contactors may optionally have a ferrule. Therefore, the term "outer perimeter" means the edge of the contactor with parallel passages or the edge of the ferrule of the contactor with parallel passages.
- the channels to be partially obstructed are filled, over at least part of their length, with resin, mastic, silicone or any element that can be applied in liquid or pasty form to permanently close the channels concerned; and or
- At least one of the ends of the channels to be partially obstructed is obstructed by a metal plate, or a plastic plate, or a silicone or rubberized seal, or any solid element that can be placed or fixed
- the obstruction may be made at the top, bottom or part of each channel concerned. It can be envisaged to block the entire length of each channel concerned.
- Figure 3 shows a parallel passage contactor with a metal plate at the upper ends of the channels to be clogged.
- Figure 4 shows an adsorber according to the invention comprising a series of parallel passage contactors with a metal plate at the upper ends of the channels to be clogged.
- the obstruction of the channels makes it possible to block the circulation of the fluid in these channels, and to create an insulation in the image of tiny blades of gas.
- the immobile gas cells being much smaller than the conventional gas blades, a much better thermal insulation is obtained.
- equivalent thermal insulation performance can greatly reduce the thickness of the insulation.
- this second alternative may be supplemented by sealing elements fixed on the outer face of the parallel passage contactors facing the inner ferrule of the bottle.
- the sealing elements are preferably chosen from brushes, seals, welds or welded elements, glue or glued elements and preferably dimensioned to overcome the possible differential expansion between the ferrule of the adsorber, and the outer perimeter of the parallel passage contactors during the regeneration of the adsorber.
- the adsorbents that may be used in the parallel-passage contactors are those used in the conventional gas stream separation or purification units. The choice depends on the application. It is possible in the same contactor to use successively several different adsorbents. Mention may be made of silica gels, optionally doped activated alumina, activated carbons, zeolites of various types (3A, 4A, 5A, type X, LSX, Y etc. optionally exchanged, etc.). The zeolites are generally used in the form of microcrystals or even nano-crystals according to the synthetic methods. Other adsorbents, for example activated carbons, can be crushed to obtain micron-sized particles.
- the contactors may be identical or on the contrary, it is possible to use this invention to singularize at least one contactor and adapt it to the operating conditions at this level of the adsorber. Regarding this modification, it may be another type of adsorbent, a change in the thickness of the adsorbent layer, the passage section, etc.
- the device according to the invention can be used in various processes such as TSA, PTSA ... It can also be used to dry, decarbonate or stop secondary impurities of a gas stream, in particular from atmospheric air.
- secondary impurities we mean the traces of hydrocarbons, NOx, SOx ...
