Definitions
- the present invention relates to a method for chromatographically separating each component from a raw material fluid containing three or more components.
- Method (1) is a batch method that scales up high-performance liquid chromatography for analysis, and is called “preparative chromatography”. However, this is not a method of performing the operation of the pseudo moving bed method.
- the method (2) is a method in which a two-component separation simulated moving bed apparatus as disclosed in Japanese Patent Application Laid-Open No. 2-124895 is used twice. That is, for the three components with a partition coefficient of A ⁇ B ⁇ C for the kerato maturing agent, component A was first separated from the mixture of components B and C in the first step, and then the mixed components B and C recovered. In the second step. In the first step, instead of separating component B having an intermediate distribution coefficient with component C as a mixture with component A, component B is separated from component C as a mixture with component A in the first step. The recovered mixed components A and B can also be separated.
- a normal simulated moving bed apparatus can only perform two-component separation, so two systems of simulated moving bed chromatographs for two-component separation are prepared, or three-component separation is performed by using one-separator twice. Do it.
- a simulated moving bed chromatographic separation apparatus for two-component separation used in this method known various types of separation apparatuses can be used.
- the c method (3) is described in Japanese Patent Application Laid-Open No. 4-227804. This is the method disclosed in the official gazette (Japanese Patent Publication No. 7-244724).
- the affinity with the filler (hereinafter sometimes simply referred to as “affinity”) are different for three or more components
- three or more fractions are continuously separated by a series of operations.
- the method (4) is a method disclosed in Japanese Patent Application Laid-Open No. 63-158105, which utilizes a fixed-bed type chromatographic separation apparatus.
- the method (5) is a method disclosed in Japanese Patent Application Laid-Open No. Hei 7-232003, which comprises supplying an eluent and a raw material liquid to a simulated moving bed apparatus comprising four unit packed beds.
- it is a method of separating into three or more fractions by repeating the process of extracting component C, which has a strong affinity.
- the method (6) is a method disclosed in JP-A-64-80409.

- Method (1) is a batch type and has poor separation performance. Therefore, it requires a large amount of high-performance and high-priced separation packing material, and is not suitable for industrial separation due to the large amount of eluent used. It is.
- Method (2) requires the preparation of two simulated moving bed chromatographs or the use of the same separator twice. If the separation device is used twice, there is a problem that continuous separation of three or more components is not possible and productivity is poor.
- the method (4) there is a step of circulating the fluid in the packed bed without supplying the fluid to the packed bed and extracting the fluid from the packed bed.
- the simulated moving bed chromatographic separation method in which the component A with low affinity and the component C with high affinity are extracted. Therefore, the circulating flow velocity in the packed bed is always constant, and the component A with low affinity tends to move too fast to catch up with the component C with high affinity.
- the separation performance is likely to be insufficient because the number of unit packed beds is as small as four, and the extraction of the B fraction stops at the extraction of a part of the effluent corresponding to the B component. It is easy to spread over the whole area, the extraction of the A fraction and the extraction of the C fraction are the total amount of the effluent from each unit packed bed, so the concentration tends to be low, and the packed bed not used for separation There is a problem that there is.
- Method (6) has a problem that it is extremely difficult to select and combine a filler, and it is difficult to implement it on an industrial scale.
- conventional chromatographic separation methods for separating three or more components include various methods such as a fixed bed method, a simulated moving bed method for separating two components, and a simulated moving bed method for separating three components.

Therefore, for the components A and B, the amount of the bed involved in the separation can be further increased, and for the component C, the amount of the bed for concentrating and recovering the C component can be increased. It is possible to more strongly prevent the C component from being overtaken by the next A component because the C component travels too slowly in the packed bed.
- the operations of ⁇ 2> and ⁇ 3> performed in one stage are performed independently of each other in terms of time, partially overlapped in time, or coincident in time. A method can be adopted in which the user can select whether to perform the operation at the same time.
- the operations of ⁇ 2> and ⁇ 3> are performed “independently in time” because the operations of ⁇ 2> and ⁇ 3> are performed consecutively without overlapping.
- the order of the operations of 2>, especially 3> (especially 4>) does not matter, including the case where the operation of complete circulation ⁇ 4> is interposed between them.
- the operations of 2> and ⁇ 3> overlap partially in time means that if the operations of ⁇ 2> and ⁇ 3> partially overlap each other, one operation Including the case where the operation overlaps and one of the operations is performed for a longer time than the other operation. This means that these operations start and end at the same time.
- the reasons for adopting such a method are as follows.
- the concentration distribution moves downstream while being separated in the packed bed, so it is necessary to secure the optimal amount of each substance to be removed for A and C removal. It is desirable that both operations ( ⁇ 2> and ⁇ 3>) be within a certain period of time.
- the time for performing steps 2> and ⁇ 3> is affected by the flow rate at which the fraction of each component (A component and C component) can be extracted and the flow rate of the liquid flowing through the circulation system. Change.
- the flow velocity is determined by factors such as pumps, flow meters, and piping.

Stop and close all the supply and withdrawal valves, and circulate a fixed amount of liquid in all unit packed beds with the circulation pump 10 (complete circulation in operation ⁇ 4>).
- the liquid supply position and the liquid withdrawal position are similarly moved to the downstream side of the circulation system by one unit packed bed, and the first stage of the first cycle (1) Move to.
- the concentration of the A component is increased by maximizing the extraction of A and decreasing the extraction of C to the maximum in each stage.
- the amount of packed bed involved in substantial separation can be further increased.
- the number of unit packed beds (columns) more than four was required in the conventional method. The same degree of separation performance can be secured by using a unit packed bed. That is, it is possible to reduce the number of packed beds per unit while maintaining the same separation performance, and it is possible to use a simple separation device.
- FIG. 3 schematically shows the concentration distribution of each component in step (2) of the embodiment of the present invention corresponding to Example 1, and FIG. 3 is a graph for easy understanding of the features of the present invention. Some explanation is added with reference.
- FIG. 3 (a) is a diagram schematically showing the concentration distribution of each component at the start of the extraction of A in the second stage. That is, when the peak of the fast moving component A reaches the extraction position, A extraction is started. Until the extraction of the part indicated as “A extraction” is completed, continue the A extraction, extract only the optimal A component concentration distribution area, and end the operation (in this figure, the width of 14 in the second row).
- FIG. 3 (b) is a diagram schematically showing the concentration distribution of each component at the time of complete circulation in the second stage. The liquid circulation is continued until the optimum extraction part of the peak of the slow moving component C reaches the C component extraction position (1/2 the width of the second stage in this figure).
- Figure 3 (c) schematically shows the concentration distribution of each component at the start of C removal in the second stage. Extraction of the fraction of component C is started when the optimum extraction of the peak of component C with slow moving speed reaches the C component extraction position. Continue to remove C until the removal of the portion indicated as “C removal” is completed (in this figure, the width of the 1st-4th row in the second row).
- FIG. 3 (d) is a diagram showing the concentration distribution of each component at the start of A extraction in step (2) after shifting to the third stage. After completion of C removal in Fig. 3 (c), the condition suitable for the next A removal is obtained. Therefore, the same operation as in the second stage is repeated in the third stage.

- the peak of component A which has a high moving speed
- the component B which has an intermediate moving speed
- the fraction of the fast moving component A and the fraction of the slow moving component C is continued.
- component B and component C will reach the portion where fraction A is extracted, depending on conditions, but must be extracted.
- FIG. 4 (b) is a diagram schematically showing the concentration distribution of each component at the start of the third stage.
- the third stage starts because the tip of component A reaches the next extraction position. Also, at this start point, component B still remains at the extraction position of fraction C, but extraction of fraction A and extraction of fraction C start simultaneously.
