SMB SMB A SIMULATED MOVING BED SEPARATION APPARATUS AND A SEPARATIVE METHOD WITH MULTIPLE MULTI-POSITION VALVE ATTACHED TO EACH INPUT AND OUTPUT STREAM

摘要

The invention, install a plurality of the bed distribute MPV (multi-position valve) for each input and output flow for material injection and the product discharged from the absorption chamber at a similar moving bed (SMB) separation step, the entire bed in each bed distribution MPV is not as easy to install and are grouped to be connected with some bed to a technique that enables the input and output of raw materials and products, more particularly to such feed (fluid mixture) (feed), the desorbent (desorbent) in a SMB process, of the input extract (extract), a raffinate (raffinate) and to each tube at least two beds distribution MPV for the output flow, such as, and connect the bed distribution MPV each bed of the adsorption chamber through a separate bed lines, respectively , each bed distribution MPV is full to ensure that the bed associated with the bed of a portion of the adsorption of the respective raw materials and products according to the rotation of the bed distribute the input and output locations change the bed MPV Relates to a similar process in which a moving bed separation.;
