Definitions
- Adsorber for purifying or separating a gas stream comprising a removable filling system
- the present invention relates to an adsorber for purifying or separating a gas stream and to a process for filling the adsorber with adsorbent material.
- the units VSA (Vacuum Swing Adsorption) 02 are units of separation of the gases of the air by adsorption process with modulation of pressure in which the adsorption is carried out substantially with the atmospheric pressure, called high pressure, it is between 1 bara and 1.5 bar, and the desorption takes place at a pressure below atmospheric pressure, typically between 0.3 and 0.5 bar.
- the production of gaseous oxygen reaches a purity of the order of 90% to 93% and the production range of this type of apparatus varies from 30t / d to 200t / d.
- a compressor and a vacuum pump are often used to reach cycle pressures.
- the VPSA processes in which the adsorption is carried out at a high pressure substantially greater than atmospheric pressure, that is to say generally between 1.6 and 8 bara, preferably between 2 and 6 bara, and the low pressure is below at atmospheric pressure, typically between 30 and 800 mbar, preferably between 100 and 600 mbar.
- the PSA processes in which the adsorption is carried out at a high pressure clearly above atmospheric pressure, typically between 1.6 and 50 bara, preferably between 2 and 35 bara, and the low pressure is greater than or substantially equal to the atmospheric pressure, therefore between 1 and 9 bara, preferably between 1.2 and 2.5 bara.
- V PSA which will include VSA, PSA, and VPSA.
- the (V) PSA cycles comprise at least the following steps: production, decompression, purge, recompression.
- the units generally operate with a total cycle time greater than 30 seconds and employ one to three adsorbers. We distinguish two large families of adsorbers distinguished by the direction of flow of gas, one being axial and the other radial. If the first is generally chosen for small units ( ⁇ 60 tons per day of 02 produced), the second is adapted to larger capacities.
- Axial technology must meet a number of technical constraints including the minimization of pressure losses and empty volumes, the management of a good distribution of gas, a maintenance of adsorbents that can be carried by the process gas or adsorber movements during transport from the workshop to the production site.
- the axial geometries are chosen because of their simplicity and cost.
- the adsorption processes can impose a gas flow from the bottom upwards then subjecting the granular material (s) to a fluidization limit.
- the fluidization of active granular materials can be driven by an excessive flow of gas inherent in the normal operation of the process or during an accidental flow peak.
- a solution of the present invention is an adsorber for purifying or separating a gas stream comprising:
- an upper domed bottom F2 comprising a main filling opening of a granular material; with said orifice having an inner diameter Din
- the filling system A is composed of a cylinder of a cylinder perforated over all or part of its height, of its upper bottom of diameter Dext and of its lower bottom,
- the distance Din-Dext is strictly greater than twice the size of the particles of the grain size material M
- the particle size material M is in contact at times with at least a portion of the outer surface of the system A and at least a portion of the inner surface of the upper curved bottom F2.
- the configuration of the adsorber according to the invention makes it possible to:
- the adsorber according to the invention may have one or more of the following characteristics:
- the granulometry material M is in contact with the entire outer surface of the system A within the cylindrical shell.
- the particle size material M is in contact with at least 10%, preferably at least 20%, even more preferably at least 30% of the inner surface of the upper domed bottom F2.
- the curved upper bottom F2 comprises at least two secondary filling holes of smaller diameter than the main orifice.
- the secondary orifices have a diameter 2 to 6 smaller than the main orifice.
- the granulometry material M is completed by a complementary material having a particle size MC of less than or equal to M, preferably the complementary material has a particle size MC three times smaller than the particle size M.
- said adsorber successively comprises, in the flow direction of the gas flow, N layers (N> 1): a first layer of a granular material of ADI granulometry, an Nth-1 layer of a granular material of DNA granulometry, and Nth layer of a granular material of granulometry M, with M>AD2> ADI.
- the first layer of a granular material of ADI particle size is supported by a rigid metal grid covered with a mesh fabric.
- the first layer of a granular material of ADI particle size is supported by a granular material with a grain size MGS greater than ADI.
- the granular material of the ADN granulometry is separated from the granular material of granulometry M by a flexible fabric or a rigid grid covered with a flexible fabric.
- the granular material of DNA granulometry rests directly on the granular material of granulometry M. It goes without saying that in this case the granular material of granulometry M will be selected so that it does not allow the material of granulometry DNA to flow into his breast.
- the adsorber R in question is of vertical axial geometry and comprises two bottoms, at least the upper bottom is curved.
- Figure 1 shows an example of adsorber according to the invention.
- a gas distributor can be installed at the bottom. At least one layer of active granular material is contained in the ferrule R, here two layers will be assumed.
- the first layer of ADI adsorbent material may be supported either by a rigid metal grid covered with a sufficiently fine mesh fabric to retain the adsorbent material or by a material having an MGS granulometry greater than that of the adsorbent material, thus making it possible to limit the losses while filling part of the empty volume, the latter may be detrimental to the performance of the process.
- the volume above the last layer of active material of DNA granulometry is filled with at least one type of granular material with a grain size M greater than DNA.
- a flexible fabric S preferably metal, or a rigid grid covered with a flexible fabric separates the materials of particle size DNA and M.
- the granulometry material M is in contact with a significant part of the upper convex bottom and the system A, so that in case of excessively high flow or movement of the adsorber the forces acting on the active granular materials are transmitted. to the walls of the ferrule R and to the system A via the grain size material M.
- the volume of the upper bottom is first filled with the granulometry material M in a compact manner while leaving a space in the center allowing the insertion of the system A.
- compact filling is meant a rain-type filling.
- the empty volume between the particles of the grain size material M can vary substantially due to a more or less tight stack of particles constituting it - a rain type filling is considered compact, whereas a "loose" filling during which the material is spilled without special attention is considered to be loose.
- a granular medium initially filled by any method and whose container is subjected to standardized shocks will have an intermediate compactness between the 2 compact "rain” and "bulk” mentioned above. After being put in place, the end of the system A will then be in contact with the grain size material M via its bottom D,
- the outer diameter of the system A is chosen to be smaller than the internal diameter of the outlet orifice situated on the curved bottom F2 so that balls (it may be materials of non-spherical shapes) of the granulometry material; M can be inserted in the created annulus
- additional filling holes OS (FIG. 4), of smaller diameter than that of the main orifice, make it possible to complete the filling of the convex bottom with a granular material having the same or smaller grain size MC as the grain size material M.
- a compact filling of the granular materials is necessary to ensure a maintenance over time of the contact surface between the granulometry material M and the ferrule R and the system A. If this was not the case, a complement of the granulometry material M by the annular space between the system (A) and the main fill port and / or through the orifices (OS) would be needed after the adsorber has been subjected to motion or vibration.
- Various filling systems achieve optimum compactness filling.
- an extra-granular vacuum content of the active materials of 35% can be obtained by a cross-sieve system.
- the filling of the grain size material M before setting up the system and the filling of the lower ADI DNA layers can be made in a compact manner, that is to say by a flow in rain, for filling the ferrule R of granular material of granulometry M by the space between the external diameter of the system A and the internal diameter of the filling orifice and the filling of the ferrule R of additional grain size material MC by the secondary filling orifices, c is not possible. Indeed there is not enough room to insert in these orifices the tools for a flow in rain. In case of vibration of the container, de-packing of the granular material can then be observed and lead to an increase in the desired contact area with the grain size material M.
- Figures 2 and 3 illustrate the system A by providing a diagram of a front view and a diagram of a view from above.
- the system A is provided with fixing lugs which are supported on lugs integral with the main filling opening.
- the present invention also relates to a process for filling adsorbent material with an adsorber according to the invention comprising the following successive steps: a) partial filling of the ferrule R of granular material of particle size AD2 by the main filling opening;
- the convex upper bottom F2 comprises at least two secondary filling holes of diameter smaller than the main orifice and said method comprises a step e) of filling the ferrule R with additional grain size material MC by the secondary filling orifices BONE.
