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.
Claims16
A device for performing a sorption process comprising
- a plurality of parallel corrugated layers disposed in side-by-side contiguous relation, each said layer having corrugations disposed in crossing relation to the corrugations of an adjacent layer to define crossing flow channels therebetween for an adsorptive-containing medium, each said layer having a pair of parallel walls defining a cavity therebetween, at least some of said walls being permeable to an adsorptive in the adsorptive containing medium and impermeable to sorption materials;
- and
- a sorption material in said cavity of at least some of said layers for removal of the adsorptive from the medium flowing through said flow channels.
A sorption device comprising
- a static mixer having pairs of parallel walls, each said pair of parallel walls defining a cavity therebetween and being shaped relative to an adjacent pair of parallel walls to define flow channels for an adsorptive-containing medium, each said wall being permeable to an adsorptive in the adsorptive-containing medium and impermeable to the sorption material;
- and
- a sorption material in each said cavity for removal of the adsorptive from the medium flowing through said flow channel.
A chemisorption device comprising
- a plurality of parallel corrugated layers disposed in side-by-side contiguous relation, each said layer having corrugations disposed in crossing relation to the corrugations of an adjacent layer to define flow channels therebetween for an adsorptive-containing medium, each said layer having a pair of parallel walls defining a cavity therebetween, at least some of said walls being permeable to an adsorptive in the adsorptive-containing medium and impermeable to sorption materials;
- and
- one of a liquid sorption medium and solid sorption medium in said cavity of at least some of said layers for removal of the adsorptive from the medium flowing through said flow channels.
A chromatography separating apparatus comprising
- a column;
- a plurality of packings stacked within said column, each said packing including
- a plurality of parallel corrugated layers disposed in side-by-side contiguous relation, each said layer having corrugations disposed in crossing relation to the corrugations of an adjacent layer to define flow channels therebetween for an adsorptive-containing medium, each said layer having a pair of parallel walls defining a cavity therebetween, at least some of said walls being permeable to an adsorptive in the adsorptive-containing medium and impermeable to sorption materials;
- and
- a sorption material in said cavity of at least same of said layers;
- and
- means for passing a mobile phase containing at least two materials to be separated into said column to flow through said packings for separation of the two materials by adsorption of one material into said sorption material.
