Process and device for separation in a simulated moving bed of at least one component in columns that have a suitable length to diameter ratio

摘要

The invention relates to a process and a device for separating at least one component of a mixture in a simulated moving bed, in which each of the chromatographic columns that contains an absorbent has a ratio of L (length) to D (diameter) of between 0.01 and 0.34. ;In addition, the ratio of L_TOT (length in n columns) to D (diameter) is between 0.06 and 2.3. ;It is possible to apply an axial dynamic pressure on each of the upper columns that exceeds the pressure drop of all of the columns.
