Abstract
There is a drastic change in the composition of the effluent streams of a fixed bed adsorption column when the feed and withdrawal points are periodically advanced in order to simulate moving-bed operation. These effluents are fractionated to recover a desorbent which is recycled to the adsorption column. The claimed process improves the efficiency of this fractionation by changing the locations at which the effluents enter the fractionators to correlate the compositions of the effluents and the material in the fractionators at these locations.
