Abstract
A method and apparatus for separation of an extract component from a raffinate component in a simulated moving bed chromatographic separation train system. The system includes a plurality of beds, packed with a sorbent material, connected to form a closed recycle loop. Inlets to the train are provided for a feed stream and a desorbent stream along with outlets for removal of a raffinate stream and an extract stream. Increased product throughput and yield are obtained by intermittantly introducing and withdrawing the various streams to the train while continuously recycling a portion of the fluid in the system.
