摘要： A method of managing the valves of a simulated moving bed separation system comprising at least one column of adsorbent beds split into several zones delimited by injection and draw-off points, allowing finer monitoring of a determined concentration profile. The method comprises, during each period between the shift times of the injection and draw-off points, in opening and closing a first valve located at one end of a zone according to a determined law, while opening and closing the valve downstream from the first valve in relation to the direction of flow of the recirculation flow, according to the same law with a lag, referred to as overlap time, in relation to the first valve, which is less than or equal to the period, the law imposing a constant total flow rate for the flow passing through the two consecutive valves throughout the overlap time. Applications are any simulated moving bed separation system, preferably those used for relatively small-tonnage production such as fine petrochemistry, pharmaceutical industry, certain food processing industries, etc.

摘要： The device comprises at least one column 1 that is filled with a number of beds A.sub.n having an adsorbent that are separated by a fluid distributor plate P.sub.i. Each plate is divided into a number of sectors P.sub.10 and P.sub.11, and each sector comprises at least one fluid distribution chamber 13 that is pierced with openings and a circulation space 8 in the vicinity of the openings. The chambers of the plate are connected to a line 10 for transfer to the outside.

摘要： Fluctuations, such as perturbations in the quality of the extract and/or raffinate streams removed from the circuit in a simulated moving bed (SMB) adsorptive process having at least one discrete non-separating section are eliminated or significantly reduced. This is accomplished by increasing the fluid flow rate in a portion of the circuit in response to the location of a discrete non-separating section and changing the flow rate of at least one stream that is in fluid communication with the circuit consistent with the increased flow rate in the portion of the circuit. Multiple adjustments to the flow rates of the input and/or output streams and multiple increases in the fluid flow rates in portions of the circuit may be used simultaneously when for example there is more than one discrete non-separating section.

摘要： An apparatus and process for fractionation of component mixtures by chromatography or adsorption on a simulated mobile bed comprising three, four or five zones is described. A compressed gas is injected as eluent (IE, IR) using a compressor or pump, the pressure being lower than the critical pressure of the gas. At any point in at least one zone and preferably at any point in at least two zones from the eluent injection point (IR), the gas has a compressibility coefficient substantially different to 1. A supercritical fluid or a subcritical liquid may equally be injected as the eluent. The pressure between each zone may be altered.

摘要： An apparatus and process for concentrating a selected component from a multi-component liquid using a sorbent bed having a preferential sorption rate for the selected component. The sorbent bed is enclosed in a single vessel and is operated in a simulated moving bed technique whereby the flow profile of the liquid is continually moved downwardly through the sorbent bed. Recirculation is continuous but variable and is accompanied by the injection of eluent and feedstock and the removal of extract and raffinate at preselected times, locations, and amounts as a function of the kinetics and voidage of the sorbent bed. Extract purity and operational efficiency of the sorbent bed are the result of this novel apparatus and process.

摘要： The present process comprises a means for energy savings in a process pump by combining the pump with a power-recovery turbine. The invention is particularly useful in the separation of a desired product from a mixture of components using simulated-moving-bed adsorption associated with a large circulating stream with a power-recovery turbine feature for conservation of energy relative to the known art. The improvement is particularly applicable to a process for the separation of para-xylene from mixed C8 aromatics.
