| 20100186587 | METHOD AND APPARATUS FOR CHROMATOGRAPHIC COMPONENT, SEPARATION WITH PARTIAL RECIRCULATION OF MIXTURE FRACTIONS - A method for the chromatographic separation of components of a multicomponent fluid mix by means of the Simulated Moving Bed method wherein the multicomponent fluid mix and at least one solvent are fed to inflows of a plurality of chambers containing at least one solid substance and connected to each other in series to form a closed loop. An extract stream containing at least one first component separated from the multicomponent fluid mix as well as a raffinate stream containing at least one second component separated from the multicomponent fluid mix are carried out of the chambers through a first and second outflows. At least part of the raffinate stream and/or extract stream carried off at the first and/or second outflows is preliminarily stored and recirculated to the first and/or second inflow of the chambers alternately or simultaneously with the multicomponent fluid mix and/or the solvent within one clock unit. | 07-29-2010 |
