Abstract
Disclosed is a method for the adsorptive separation by utilizing an improved simulated moving bed. This invention provides an improved formula for the calculation of primary flush flowrate by correspondingly associating the primary flush flowrate with each connection line by introducting a volume factor and carring out sequential control so as to reduce the amount of the flush stream and increase product purity and yield.
