Verfahren und Anlage für die adsorptive Stofftrennung

摘要

The invention concerns a method of carrying out adsorptive substance separation by permeating fluids through porous adsorbers. It also concerns an installation for carrying out this method on an industrial scale. According to the invention, instead of a method using adsorber modules connected rigidly in series, a so-called tandem method is applied. It is based on the fact that, with an adsorber, the target substance breaks through only in the final phase of charging with the adsorbed substances, and therefore the connection in series is advantageous only in this phase. Consequently, adsorber modules are used in two identical stages A and B together with two pumps, either in each case precisely one stage being charged and the other eluted or regenerated cyclically or both being operated in series. The method and installation can be used in the fields of biotechnology, genetic engineering, pharmacy and chemistry, the drinks and foodstuffs industry and in environmental protection.
