Definitions
- the present invention relates to a process for the selective separation of at least one component from a gas mixture by adsorption using at least one adsorbent material chosen as a function of the gas mixture and of its components to be separated selectively.
- FIG. 1 An example of a commonly used PSA (Pressure Swing Adsorption) system is shown in FIG. 1 and comprises two or three reservoirs A, B, C, filled with specific adsorbent material (s).
- a gas blower to be treated D feeds one of the tanks A, B, C, by opening the corresponding valve E.
- the gas to be treated (for example air) passes through one of the tanks, for example A, in which the gas to be rejected is adsorbed, the non-adsorbed gas (for example oxygen) leaves the tank A via the valve FA open at this time, and the tank G, towards use.
- the reservoir B is evacuated by means of a vacuum pump H via the corresponding valve IB.
- the adsorbed gas for example nitrogen
- the reservoir C previously evacuated, is filled by introducing pure gas via the valve FC, the corresponding valve IC being closed. With this operation, the adsorbed residual gas is discharged down from the tank C, the upper part of the tank C being completely desorbed. This operation is "repressu ⁇ risation". After a fixed period of time, the circuits are inverted, i.e. gas to be treated towards the tank B, evacuating the tank
- FIG. 3 representing the characteristics of gas adsorption for a molecular sieve or adsorbent material. specific for nitrogen adsorption from air
- the partial pressure P of the gases is plotted on the abscissa and the mass M of gas adsorbed on the ordinate.
- the distribution in atmospheric air is of the order of 80% nitrogen (N 2 ), gas to be adsorbed, for 20% oxygen (O 2 ). So, for a crude gas (or air) pressure of 1.2 bar, the partial pressure of nitrogen is of the order of 0.95 bar and there corresponds a mass of nitrogen ni and that of oxygen is of the order of 0.25 bar and it there corresponds an oxygen mass o1
- valves E and I which equip the reservoirs, FIG. 1, and which operate approximately every 30 seconds at least, and therefore perform approximately one million operations per year, while the molecular sieve allows a significantly higher frequency of operations.
- the quantity of molecular sieve, an expensive material, to be used is very high.
- the maintenance cost of these valves E and I which are highly mechanically stressed when it comes to valves for high flow installations, is very high.
- the known systems include six valves of large dimensions and operating at high frequency for the dimensions used; this constitutes a limitation of the production capacity of the known units, for example to a limit of ⁇ 100 T / d of pure gas for the case of oxygen, beyond which the unit cost of the equipment becomes prohibitive.
- the speed of passage of the gases in the molecular sieve or adsorbent mass, at the right of the injection of gas to be treated and at the outlet of the desorbed gases, is very high. This leads to an erosion of the adsorbent mass. Indeed, the mass of desorbed gas can represent approximately ten times the mass of pure gas produced.
- these large variations in the flow rate of gases in the molecular sieve do not allow rational use of the adsorption / desorption properties of these materials.
- the object of the present invention is to remedy the drawbacks of known techniques and methods, and in particular: to significantly reduce energy consumption by more than 20%, to reduce the mass of expensive adsorbent material by more than 40%, to reduce maintenance costs and improve the reliability of the gas separation device, - reduce the investment costs of the units.

- a duration of a cycle of the four phases is divided into four quarters of equal duration for each phase and a quarter of duration is chosen so as to be less than a time limit for saturation of the adsorbent material contained in a container and not by the mechanical strength of the devices.
- the determined vacuum is between 0.2 and 0.5 bar absolute and is preferably of the order of 0.3 bar absolute; then the determined pressure higher than atmospheric pressure is advantageously between 1, 1 and 2 bars absolute and is preferably of the order of 1, 2 bars absolute.
- the determined pressure greater than atmospheric pressure is advantageously between 2 and 7 bars absolute and is preferably of the order of 4 to 6 bars absolute; the determined vacuum is then between 0.3 and 0.7 bar absolute and is preferably of the order of 0.5 bar absolute.
- a passage of the gas mixture is arranged so that it circulates at practically constant speed through the adsorbent material, compensating for its loss of component ( s) adsorbable (s) by a progressive reduction in the cross-section of passage through the adsorbent mass, and for desorption, a passage in the opposite direction of the gaseous components is arranged through the adsorbent material so that they circulate at a speed that is also practically constant, as a function of the gradual increase in the volume of gas desorbed.

- the passage of the gas and the aforementioned passage surfaces are arranged so that during adsorption, on the one hand, the gas mixture entering through the intake grid and progressing in the adsorbent material and, on the other hand, the non-adsorbable component (s) discharged through the discharge grid have a practically constant speed and so that during desorption, a passage in the opposite direction of the gaseous components also takes place at a practically constant speed,

- a sealing ring is arranged each time
- the intake and / or evacuation and / or separation grids have passage holes whose circumference is each time a frustoconical surface pierced at the point which it - even is directed towards the adsorbent material, avoiding blockage by the adsorbent material.
- the seals and the seal sections are grooves longitudinaleme ⁇ t either on their face facing the rotor when they are carried by the stator or on their face facing the stator when carried by the rotor, so as to cause a labyrinth effect for any gas between two contiguous stages of the distributor
- frustoconical containers are preferred for the production of nitrogen as a non-adsorbable component and they preferably have a ratio of 0.6 to 0.8 between their base diameter and that of the top and a ratio of 0, 8 to 1, 5 between their average diameter and their height, these frustoconical containers being further advantageously arranged so that their axes of revolution are vertical.

- Figures 4 and 5 show a device according to the invention.
- This new device comprises four cylindrical containers 1 to 4 equipped with separation grids 5 and 6 between which are the molecular sieves 7 used for the adsorption and desorption of gases under the effect of programmed variations in pressure.
- These adsorbent materials 7 are composed of specific materials depending on the nature of the gases to be adsorbed, for example H 2 O, N 2 or O 2 , etc.
- a gas distributor 8 is composed of a stator 9 and a rotor 10 The latter is driven in a sequential rotary movement by a motor device 11 (by successive quarter turns)
- a gas blower to be separated 12 sends the gas to a stage of the distributor 8 Likewise, an incorporation pipe by suction of gas to be treated is connected to another stage of the distributor 8 via the conduit 13
- a vacuum pump 14 is connected to the distributor 8, on the fourth floor
- a fifth stage of the distributor 8 collects the gases from the high desorption, explained below, via the conduit 15, the reservoir 16, the non-return valve 22 and the vacuum pump 14
- valves 17 The pure gas leaves one of the containers 1 to 4 via valves 17 and is collected in a tank 18 before use. In addition, it is carried out reverse rinsing of the molecular sieves or adsorbent materials 7 by incorporation of pure gas by means of valves 19 Although this does not appear in the diagrams of Figures 4 and 5, valves 19 are part of a flow control system while valves 17 are not part of it.
- the four containers are connected to the part distributor central 8 via pipes 20 and filters 21
- the gas distributor 8 is divided into five stages
- the rotor 10 and the stator 9 are provided with gas passage orifices and circular and vertical seals described below
- the rotor 10 is internally divided into four longitudinal compartments a, b, c , d
- Part of the gas to be treated is introduced by natural aspiration into a container 4, for example under vacuum via a conduit 13, the distributor 8, the internal conduit d, the conduit 20 and the corresponding filter 21
- This container was previously under vacuum (approximately 0.3 bar absolute)
- the gas to be treated fills container 4, from the periphery towards the center, and its pressure rises gradually to a value close to atmospheric pressure
- a large quantity of gas is adsorbed in the molecular sieve 7, without removal of the non-adsorbed gas
- the adsorbed gases contained in the molecular sieves of the reservoir 2 are desorbed, by suction using the vacuum pump 14 via the conduit 20, the filter 21, the distributor 8 and the internal channel b of the rotor 10
- the pressure is therefore gradually lowered in this tank 2
- the final desorption of the gases contained in the molecular sieves 7 of the reservoir 3 already vacuum is carried out, by incorporation of pure gas via the corresponding valve 19
- This gas strongly lowers the partial pressure of the gas adsorbed in the molecular sieve 7 and rejects the latter to the vacuum pump 14 via the conduit 20, the filter 21, the distributor 8, the internal channel c, the conduit 15 and the intermediate tank 16 which is maintained under a certain regulation vacuum thanks to the action d 'a non-return valve 22
- the non-return valve 22 opens at point R of phase L4 when the pressure R' of phase L3 has become sufficiently low, about 0.5 bar
- a particular form of the distributor 8 is shown and it constitutes an essential part of the device of the invention since it ensures an operation adapted to the kinetics of adsorption / desorption of the molecular sieve 7 and to the carrying out of the specific cycles of the process invented.
- Figures 4 and 5 and Figures 7a and 7b give the representation of a distributor 8 applied to the invention
- the rotor 10 has longitudinal partitions forming channels a, b, c, and d ( Figure 5).
- the distributor 8 comprises five stages separated by annular seals 23. Four stages correspond to the four phases of the process and the central stage distributes the phases to the containers. On the central floor, there are 24 "vertical" seals to seal between the containers. Splitting the vertical joints 24 eliminates a short circuit during the rotation of the distributor 8 and, moreover, halves the rate of leaks.
- a sealing ring 30 can be arranged each time mounted so that it can slide so sealed in the conduit 20, along the axis thereof.
- the sliding is provided so that the ring 30 can be brought into abutment against the rotor 10 by one of its ends which is shaped to the diameter of the rotor 10, to conform to the shape and to ensure there a sealed contact, and which is open to be able enter into selective gas passage communication with a respective orifice of the rotor 10.
- the other end of the ring 30 opens in the corresponding conduit 20 (provided for example with a connection flange 31).
- the sealing ring 30 is pushed, at least in service, by means 32, such as a helical spring, against said rotor 10 for sealing.
- means 32 such as a helical spring
- a person skilled in the art is able to choose the material or materials best suited for the ring 30 and for the seal which it must provide in order to also eliminate any leakage and / or a gas short-circuit from a orifice thus equipped towards another orifice of the distributor 8 during the rotation of its rotor 10.
- the rotor 10 is stopped during the running time of each phase, then performs a rotation of a quarter turn in less than a second.
- the average speed of rotation of the distributor 8 is of the order of one revolution per minute. This system therefore makes it possible to apply short phase times, linked to the adsorption / desorption performance of the molecular sieve 7.
- the parts of the rotor 10 in contact with the seals 23, 24, if necessary the sealing rings 30, are filled with a layer of ceramic oxide of very hardness, layer treated by polishing to reduce the forces. friction (shaded in Figure 7b) Constant speed gas transfer container
- a particular feature of the invention is the distribution of the gas within the adsorbent masses 7
- a particular form of distribution of the gases in the containers 1 to 4, particularly for the production of oxygen from the air, is explicit in view of Figure 8
- the gas to be treated is introduced into the container via a pipe 20 through the periphery
- a special grid 5 of large area allows the gas to be distributed homogeneously, at low speed in a first adsorbent mass 7A, to retain a elements of the gas, H 2 O for example
- the grid 5 has special characteristics, and in particular has conical holes whose tip is turned towards the adsorbent material and is pierced, so as to prevent any obstruction of these orifices by the adsorbent mass 7
- the gas continues to run horizontally and passes through a grid 25 separating the adsorbent material 7A from another adsorbent material 7B which r is a component of the gas, N 2 for example After adsorption of this gas, the pure gas (not adsorbed)
- non-adsorbable component (s) means the component (s) which it is wished to leave through the reservoir 18 and lead to what is called use. It goes without saying that there can always be a relatively weak adsorption of the non-adsorbable component (s).
- the orifices provided in the stator 9 and rotor 10 for the selective matching of the receptacles 1 to 4 with specific gas conduits via the channels a, b, c and d need not be better described. It can be specified, however, that to facilitate the passage of the "vertical" seals 24, it is advantageous that the orifices 26 (FIG. 7b) of the central stage of connection to the containers 1 to 4, on the rotor 10, are formed of several circular holes, like a colander.
- the orifices 27 of the other stages do not pose any problem of passage of seals and can be formed in various ways depending on what the skilled person considers best suited to the case in hand.
- the seals 23 and 24 are shown fixed on the stator 9 They can however just as easily be mounted on the rotor 10 They preferably have, on the side of the element on which they are not fixed but on which they rub, grooves longitudinal forming labyrinths for gas tending to pass from one floor to another
- the containers, tanks, distributors, etc. can occupy, as the case may be, the necessities and the choice of the person skilled in the art, a position different from the vertical position shown in FIGS. 4, 5, 7a, 7b, 8 and 9 quantified advantages of the method and the devices according to the invention
