Definitions
- the present invention relates to the field of centrifugal liquid-liquid chromatography apparatus, and more particularly to the cells and their connecting channels for liquid-liquid centrifugal liquid chromatography apparatuses, as well as to their method of manufacture.
- a known technique for separating components A and B in solution in a liquid mixture consists in injecting it into a chromatography column subjected to a centrifugal force, which is designed so that one of the liquid phases can be percolated in the other liquid phase and reciprocally (so-called CCC or CPC chromatography).
- this type of chromatography system comprises one or more stacks of discs driven in rotation.
- Each of them has in its thickness and over its entire periphery a succession of cells arranged in a radial or oblique direction and put in series by a set of circuits tortuous fine pipes at the ends of each cell.
- the circuits of all the disks communicate with each other other.
- the cells and their communication circuits are filled with a stationary liquid phase held in place by the centrifugal force and another mobile liquid phase which percolates through the stationary phase.
- the rotation of the stack creates a large centrifugal acceleration field which makes it possible to maintain the so-called fixed stationary liquid phase, whereas the mobile phase circulates in the so-called ascending mode if it is lighter than the stationary phase, and in descending mode if it is heavier.
- the chromatographic process that is to say the sharing of the molecules to be purified between the two liquid phases, takes place in each cell, and the mass transfer is favored by a good dispersion of the mobile phase arriving from the channel in each cell.
- a first and double disadvantage of this prior art is due to the very design of the cells dug through the thickness of the disks which requires the installation of seals, generally flexible, for example Teflon, between each disk, closing and each cell according to the plane of the disk, so perpendicular to the main axis of each cell.
- seals generally flexible, for example Teflon
- the cell has rounded shapes to facilitate the homogeneity of the dispersion for a better exchange of materials between the two phases
- the planes of the joints create with the cell right angles not conducive to a homogeneous dispersion of liquids.
- these planes of flexible joints subject to continuous pressure variations of the liquids, deform over time and changes the geometry of the cells, resulting in aging of the instrument.
- a second disadvantage comes from the fact that the cells are interconnected by a ribbon-shaped channel. It is easily calculated and verified that this form of duct, for a given section, produces a loss of charge much higher than that caused by a duct of the same section but square or cylindrical. To limit excessive pressures and in some cases for reasons of difficulty in machining, it is necessary to increase the thickness of these ducts, thus to increase the dead volumes in which the products being separated partly re-mix, thus reducing the efficiency and productivity of the device.
- the thickness of the duct is not perfectly constant over its entire length, which is the case when the cells are cut by a jet of water, a gradient of the velocity vectors of the moving liquids (phase and compounds to be separated), between one side and the other of the disc, which has a tendency to spread the compounds being separated, thus to re-mix them and, consequently, to reduce the performances of efficiency and productivity of the machine.
- the object of the present invention is therefore to overcome one or more of the disadvantages of the prior art by proposing cells (1) for a centrifugal partition chromatography column consisting of stacked disks and comprising a network of three-dimensional cells interconnected in series and communicating with each other. with circulation channels of the liquid phase and distributed at the periphery of at least one disk rotated around a main axis (8), the cells have a geometric shape of revolution about a substantially radial axis with respect to said disk and are connected by channels (2, 4) of substantially circular section, elliptical or parallelepiped whose two main dimensions are smaller than the largest cross section of the cell.
- the geometrical shape of revolution is defined by three main dimensions along three axes X-X ', YY' and ZZ 1 , ZZ 1 being parallel to the axis of rotation of the disk, the axis Y, Y 'being radial with respect to the disk, and the X axis, X' orthogonal to the other two axes, said three dimensions being substantially identical.
- the dimension along the axis X-X ' is greater than the two other dimensions along the axes Z-Z' and Y-Y '.
- the dimension along the axis YY 1 is greater than the two other dimensions along the axes ZZ 1 and X-X '. In another embodiment of the invention, the dimension along the axis
- ZZ 1 is greater than the other two dimensions along the axes YY 1 and X-X '.
- the dimensions along the axes X-X ', YY' and ZZ 1 are different.
- the cells according to the invention may be arranged at least two by two one after the other along the axis YY 'forming at least one pair (5) of cells repeated regularly on a circle parallel to the plane of rotation of the disc (3).
- the cells (1) are arranged in at least two concentric circles parallel to the plane of rotation of the disk (3).
- the cells (1) of the pair (5) of cells according to the invention are connected by a channel (4) for circulating the S-shaped liquid phase.
- the axis formed by the arrival of the circulation channels of the liquid phase is parallel to the axis YY 1 .
- the axis formed by the arrival of the circulation channels of the liquid phase is superimposed on the Y-axis Y '. In another embodiment of the invention the axis formed by the arrival of the circulation channels of the liquid phase is shifted relative to the axis YY 1 .
- the invention also relates to a method for manufacturing cells (1) according to the invention consisting in machining half-cells on a disk (3) and its mirror (3 '), the disks (3, 3') being then assembled two by two to reconstitute an entire cell (1).
- the assembly of the discs (3, 3 ') is done by welding.
- the assembly is done with a seal (6).
- the channels (7) for circulating the liquid phase are formed directly in the seal.
- FIG. 1 represents a block diagram of a cell according to the invention with input and output channels with a substantially round, square or rectangular section according to the invention.
- Figures 2, 3 and 4 show different embodiments of the cells and channels according to the invention.
- FIG. 5 represents an example of concentric assemblies of cells on the same disk making it possible to increase the useful capacity of a rotor.
- Figures 6, 7 and 8 show examples of constructions and disk assemblies.
- Figure 9 shows the distribution of liquids in cells according to the invention.
- FIG. 1 illustrates a cell (1) according to the invention.
- the base of this cell (1) has a geometry of revolution.
- the cells according to the invention can thus be adapted from the sphere to the spheroids and other similar forms of revolution by modifying the respective ratios of the lengths of the X-X ', Y-Y' and Z-Z 'axes.
- the axis ZZ ' being parallel to the axis of rotation (8) of the main disk having the cells shown in Figure 8, the Y axis, Y' being radial relative to the disk, and the axis X, X ' orthogonal to the other two axes ( Figure 1, 2, 3, 4, 5, 6 and 7).
- the axis of revolution of the shape of the cells is close to the radial direction of the disks.
- the axis of revolution is in the radial direction.
- the channels (2, 4) connecting these cells between them have a section defined by two main directions that will determine their shape.
- the cells will have a section circular, square or rectangular or very close to one of these forms, the channel section being smaller than the largest cross section of the cell.
- the cross section of the cell being defined as the section perpendicular to the radial axis with respect to the disk.
- This section of the cells can also be defined by the axes XX 1 and Z-Z '.
- This type of channel shape makes it possible to reduce the pressure drop due to the liquid flow, and also to reduce the dead volume while improving the profile of the liquid velocity vectors with respect to a ribbon-shaped duct.
- these channels may have a section whose two main directions are smaller than the dimensions along the axes XX 1 and ZZ 'of the cell. For example, the width and length of a rectangle section will be smaller than the dimensions along the axis XX 'and ZZ' of the cell.
- the respective dimensions are optimized according to the X, Y, Z axes.
- the shapes of revolution are thus modified according to the 3 axes of the cell.
- the Y axis is substantially in the same axis as that of the centrifugal force. It is known that the hydrostatic pressure, for a given force, increases with the height of the cell along this axis. In the case of an enlargement of scale of such an instrument, the magnification is limited along the Y axis and the enlargement of the dimensions of the cell along the X and Z axes is preferred, in order to limit this pressure.
- FIGS 2, 3 and 4 illustrate different forms of cells obtained by changing the dimensions according to the X, Y and Z axes.
- the cells (1) are spherical, the dimensions along the X, Y and Z axes have substantially the same values.
- the cells (1 1 ) are ovoid and the dimension along the X axis has been increased relative to that of the Y and Z axes.
- FIG. 4 illustrates two types of spherical cells (1).
- FIGS. 2, 3, 5, 6 and 7 show an example of another embodiment of the invention, the mode "Twin” or pair (5), where the cells are grouped in pairs in series and connected between they by channels (4).
- These figures are not limiting because in some applications, it is interesting to make groups of several cells on the principle of "Twin". For example, in the case of Figure 5 couples (5) of cells are arranged on two concentric circles. These configurations representing the torque version are by way of non-limiting example because one can also achieve the same systems with one or more cells.
- a first manufacturing method consists in machining half-cells on a disk (3) and its mirror or symmetrical mirror (3 ') with respect to the flank of the disk, as illustrated for example in FIG. 6 which shows sections of a stack of four disks according to the invention.
- the end discs are machined on one side, while the other discs are machined on both sides.
- the disks are then assembled to form whole cells by electron beam welding or any other molecular scale surface welding process.
- the discs can be made of plastic materials such as Teflon and pressed against each other, thus ensuring tightness (Figure 8).
- Another manufacturing method consists in making the cells by lost-wax casting, a well-known method, for example in the field of aeronautics where it is used for the manufacture of turbine blades of the reactors.
- Cell production can also be done by injection / extrusion of plastic materials which is a method well known to those skilled in the art.
