Process for controlling a separation system with simulated moving beds

Process is claimed for controlling a system for separating constituents in moving beds, with a closed loop formed by the interconnection in series of the beds containing an adsorbent solid material, divided into several zones delimited by fluid injection and extraction points. The process uses the m...

Summary:Process is claimed for controlling a system for separating constituents in moving beds, with a closed loop formed by the interconnection in series of the beds containing an adsorbent solid material, divided into several zones delimited by fluid injection and extraction points. The process uses the means of injecting and extracting fluids into and out of the loop; means of permutating the points of injection and extraction allowing the displacement of the beds to be driven in counter-flow, and means of measuring the operating variables. The device includes: measurement at a number of points along the loop of the variables characteristic of the injected and extracted fluids and the variables characteristic of the process function; determination from the current values and a model of unit separation, of the indicative ratios (Rk) in each zone between the fluid flows (Qk) and the flows of the adsorbent material (Qs) to get or retain the control values (xi) to a determined control value; and the determination from these ratios of the values to be given to the operating variables.
