continuous process and device chromatographic separation of a mixture of at least three constituents into three effluents purified by a single solvent at two temperatures and / or two different pressures.

摘要

SE describes a device and a method of separating CONTINUOUS AND FLUID PHASE OF A MIXTURE OF AT LEAST THREE CONSTITUENTS into three fractions. USED ​​a technique CONTRACORRIENTE simulated in a separation column filled with an absorbent having five zones 6, 5, 4, 3 and 2 DIFFERENT FUNCTIONS AND PERFORM THE SEQUENCE OF FOLLOWING STAGES: INTRODUCED THINNER STRONGER S2 is extracted UN EXTRACT E2 in the strong solvent is introduced the same solvent but at a temperature and / or at a low pressure (solvent S1 WEAK), SE SACA EXTRACT IN SOLVENT WEAK E1, INTRODUCED mixture to be separated is extracted REFINED IN THINNER WEAK R, RCY is recycled to power ALTERNATELY CURRENT SOLVENT STRONG S2 and then to the solvent feed WEAK S1. IS SENT FROM A zone 6 ALTERNATELY CURRENT OUTPUT TO A STRONG SOLVENT EXTRACT S2, and then to the entrance Zone Five. ADVANCING SEHACEN synchronous periodically so through the column the various feeds and outputs. ESPECIALLY THE SEPARATION APPLICATION OF GLUCOSE, xylose and arabinose AND CONTAINING water purification phenol, p-cresol and toluene.
