Abstract
Abstract The device for the performance of sorption processes is in the form of a static mixer and comprises a number of folded double-walled layers which contact one another. The layers are double walled with at least some of the resulting gaps being filled with sorption material. The walls of the layers are permeable by the adsorptives and impermeable by the sorption materials. The device can be used with advantage for chromatography separation processes and permits use of a broad spectrum of sorption materials, increases the working life and improves process reliability.
