Notes:
By applying a temperature profile to the system, the concentration of the extract product in a countercurrent adsorption separation process may be increased relative to the maximum concentration attainable under isothermal conditions. To achieve the required temperature profile in a simulated countercurrent system it is necessary to heat and cool the columns in sequence as the feed and product draw-off points are switched through the bed. The practical feasibility of operating the system in this way has been demonstrated experimentally for the separation of glucose-fructose mixtures. By maintaining a temperature difference of 30-35°C across the bed an extract product containing 28% fructose and about 1% glucose was obtained, at steady state, from a feed containing 25 wt. % of each sugar.
