In the middle of the product utilizing enzyme to carry out decomposing, often because of impurity contained in by product or raw material, cause the existence of impurity.Therefore, for a SMBC, the reaction solution after enzyme reaction, except the filtration of necessity, also must consider that in reaction solution, solvability impurity is on the impact of SMBC.These impurity general all belong to acid or the aldehyde of molecular weight, and therefore its anelasticity is all taller than glucose.Therefore, while separation trehalose and glucose, most impurity all can also flow with glucose and go out.Except this can be contained impurity glucose more further other to be separated with SMBC except, the SMBC with on-line cleaning function also can be utilized to carry out the function of Impurity removal.
Fig. 8 illustrates the tubing string configuration schematic diagram of In-Situ Cleaning-simulation moving-bed (CIP-SMB) chromatography, suppose that the delay intensity of A/B/C tri-kinds of compositions in tubular column system is sequentially composition A< composition B< composition C, then the design of Fig. 8 can make three kinds of compositions effectively be separated.Fig. 8 shows In-Situ Cleaning-simulation moving-bed (CIP-SMB) chromatography schematic diagram, for 8 tubing strings SMB and to set configuration be 1-3/1/3/0, being separated of composition B and A is identical with the method for traditional SMB, but the composition C of strong anelasticity, then taken to the 0th section (pre-treatment section), carried out desorption with the strong desorbing agent of another kind simultaneously.Recycling punching is subsequently washed after agent is soaked and is got back in SMB system.In operational design, the separation of composition A/B must meet formula (3).But because the anelasticity of composition C is stronger than composition B, so the composition C of flowing of turning left is easy to along with composition B is extracting the outlet outflow end, and pollute B product.For a real moving-bed (truemovingbed is called for short TMB), such pollution also cannot be avoided, but for SMB, as long as utilize the concept of single tubing string, also can the product that end obtains pure composition B extracting.Pollute to extract in order to composition C will be avoided and end, operationally need to be controlled especially.Fig. 9 describe how to utilize the concept of single tubing string to avoid composition C from extract end flow out.
Fig. 9 illustrates that application In-Situ Cleaning-simulated moving bed chromatography method is separated the conceptual schematic view of three kinds of compositions.After A/B/C tri-kinds of composition chargings, composition C is washed by punching the 3rd section that the right is taken in agent, blacking part in Fig. 9, then when next switching time, it is the second section that the position of this tubing string is adjusted to, then the switching continued through once is later again by migration first section.As long as the number of switching time, flow velocity and each section tubing string can make the part of blacking can not end and flow out from extracting, composition C just can be allowed completely to flow out from the 0th section.Therefore the operation of the second section and the 3rd section still must meet following restricted condition:
N in formula
2it is the tubing string number of the second section.
Except second and the 3rd section restriction except, the operation of the 0th section also will meet following two conditions:
K in formula
c orepresent the Henry's constant of the composition C of the 0th section, m
orepresent the relative velocity of the 0th section.Because use different rushing to wash agent, so K
c owith K
cnot identical.
Figure 10 illustrates the separable operational condition coordinate diagram of In-Situ Cleaning-simulated moving bed chromatography method according to triangle balanced.The design of this embodiment is at traditional (m
2, m
3) coordinate plane is drawn, then as shown in Figure 10, the separable operational condition region of figure intermediate cam shape Regional Representative.Right-angle triangle Regional Representative in Figure 10 can be separated the operational condition of the two composition of A/B, the inequality of the thick line representative formula (9) in Figure 10.Owing to must meet formula (3) and formula (9) simultaneously, so the operational condition of separated component A/B/C completely the K of figure can be arranged in
athe delta-shaped region that-P-Q is linked to be, and P point also represents best operational condition.So, K
ait is larger that-P-Q surrounds leg-of-mutton scope, then the efficiency of SMBC is higher.Therefore, the tubing string number n of the second section in the design of SMBC
2little.
