| 简介 |
The present invention relates to an apparatus for adsorbing and separating a simulated moving bed, comprising : a mixture inflow port, a raffinate discharge port, a desorbent inflow port, an extract discharge port, and one or more product re-injection ports for re-injecting a product discharged from one or more discharge ports selected from the raffinate discharge port and the extract discharge port; a chromatography unit including chromatography intervals for connecting two adjacent ports; and a valve unit including one or more valves for controlling the movement of each of the ports at preset time intervals. The present invention can increase separation efficiency including the purity of final products by re-injecting a part of the product through the product re-injection ports.(AA) Fluid flow and port movement direction(BB) Desorbent (D)(CC) Area I(DD) Extract (A)(EE) Area IV(FF) Area II-1(GG) Product re-injection port 1(HH) Area II-2(II) Raffinate (B)(JJ) Area III-2(KK) Area III-1(LL) Product re-injection port 2(MM) Mixture to be separated (Feed, A+B+D)COPYRIGHT KIPO 2014 |
