초록 ▼

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.

대표청구항 ▼

A process for separating a mixture of two or more chemical compounds by liquid chromatography which comprises the steps: (a) passing a feed stream comprising a mixture of at least a first chemical compound and a second chemical compound into a first rotary valve which selectively directs the flow of the feed stream into a first adsorbent chamber, of a plurality of serially interconnected adsorbent chambers, via a first conduit connecting the first rotary valve and the first adsorbent chamber; (b) passing a desorbent stream comprising a desorbent compound into a second rotary valve which selectively directs the flow of the desorbent stream into a second adsorbent chamber of said plurality via a second conduit which connects the second adsorbent chamber and the second rotary valve; (c) withdrawing an extract stream comprising the first chemical compound from a third adsorbent chamber of said plurality via a third conduit which connects the third adsorbent chamber to a third rotary valve; (d) withdrawing a raffinate stream comprising the second chemical compound from a fourth adsorbent chamber of said plurality via a fourth conduit which connects the fourth adsorbent chamber to a fourth rotary valve; (e) advancing liquid process streams in a unidirectional manner through at least all but one of the adsorbent chambers of said plurality via a fifth rotary valve which is connected via conduits to the inlet and outlet ends of each of the adsorbent chambers of said plurality, with the fifth rotary valve allowing free passage of the process streams between all of the adsorbent chambers except between the second adsorbent chamber, which is receiving the desorbent stream, and the immediately upstream adsorbent chamber; and, (f) indexing the position of each of the rotary valves in unison to change the conduits carrying the feed, desorbent extract and raffinate streams and to thereby incrementally change the chambers receiving or discharging these streams such that the movement of adsorbent within the adsorbent chambers is simulated.
