  • Process for separation in a simulated moving bed of at least one component in columns that have a suitable length to diameter ratio
    Patent number: 6533940
    Abstract: The invention relates to a process for separating at least one component of a mixture in a simulated moving bed, in which each of the chromatographic columns that contains an adsorbent has a ratio of L (length) to D (diameter) of between 0.01 and 0.34, and the ratio of LTOT (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.
