Abstract
A pressure swing adsorption apparatus for the removal of one or more components such as oxygen from a mixture of gases such as air is disclosed. The apparatus includes pairs of columns (14, 16) for receiving a stream of compressed air with one column operating in a working mode whilst the other said column operates in a purging mode. The columns contain carbon molecular sieve material (26) for adsorbing oxygen and a desiccant material formed into a plurality of tubes (28).
Claims17
A pressure swing adsorption apparatus for the removal of at least one component from a mixture of gases, the apparatus comprising a plurality of columns for receiving a stream of gas, at least one said column adapted to operating in a working mode whilst at least one other said column operates in a purging mode, said plurality of columns containing at least one carbon molecular sieve material for adsorbing at least one component of said of gas and at least one desiccant material, wherein said at least one desiccant material comprises at least one polymer binder, and wherein said at least one desiccant material is formed into a plurality of tubes, wherein the plurality of tubes are aligned axially with the column and formed into a bundle so that the stream of gas travels through the internal diameter of the plurality of tubes and wherein the polymer binder comprises polyether sulphone.
A pressure swing adsorption apparatus comprising a column, the column comprising:
- an input for receiving a stream of gas;
- an output;
- a plurality of tubes in direct fluid communication with the input, the plurality of tubes comprising a desiccant material and a polymer binder, the polymer binder comprising polyether sulphone;
- and
- a carbon molecular sieve in direct fluid communication with the output;
- wherein the plurality of tubes and the carbon molecular sieve are in direct fluid communication, and the plurality of tubes are aligned axially with the column and formed into a bundle so that the stream of gas travels the internal diameter of the plurality of tubes.
A pressure swing adsorption apparatus comprising a plurality of columns, wherein at least one of the plurality of columns comprises:
- a carbon molecular sieve material;
- and
- a plurality of tubes comprising a desiccant material, the desiccant material comprising adsorption crystals and a polymer binder comprising polyether sulphone, and the plurality of tubes are aligned axially with the column and formed into a bundle so that the stream of gas travels the internal diameter of the plurality of tubes.
