Abstract
A simulated moving bed separator and methods for isolating a desired component are provided. A method includes removing an extract from an extract bed of the simulated moving bed separator, where the extract includes the desired component, and where the simulated moving bed separator includes a plurality of adsorbent beds circularly coupled together. The simulated moving bed separator also includes a distributor and a plurality of conduits fluidly coupling the distributor to the adsorbent beds. The adsorbent beds include the extract bed and a secondary flush bed downstream from the extract bed. A secondary flush conduit is flushed with a secondary flush fluid while removing extract from the extract bed, where the secondary flush conduit fluidly couples the secondary flush bed with the distributor. The flush fluid includes the extract.
