  • Apparatus for regulating the flow rate of at least one fluid in simulated moving bed separation units
    Patent number: 6332982
    Abstract: An apparatus and process for regulating the flow rate of at least one fluid or effluent circulating in a simulated moving bed comprises a plurality of beds disposed in a closed loop in at least one chromatographic column (1) and comprising at least one means for recirculating fluid and comprising at least two lines for injecting fluid at a controlled flow rate and at least two lines for withdrawing fluid, one of said withdrawal (extract or raffinate) lines being under flow rate control, the other (60) being under pressure control via at least one control valve (6), and is characterized in that said pressure controlled withdrawal line (60) comprises, in addition to the control valve, comprises at least one restriction means (201) enabling the pressure downstream of at least one of the beds to be reduced. One embodiment of the use of the invention is for separating a xylene isomer.
    Type: Grant
