ABSTRACT:
Various chemicals such as pharmaceuticals and petrochemicals are chromatographically separated in pilot plant quantities using an apparatus comprising a number of chambers containing an adsorbent linked together with valving necessary to simulate the continuous countercurrent flow of the adsorbent and liquid phases. The apparatus preferably comprises five multiport rotary valves, each having at least one port for each column. The fifth rotary valve provides a serial interconnection between the columns and also ensures the desired unidirectional flow of fluid in the apparatus.
