METHOD AND APPARATUS FOR REMOVING WATER FROM COMPRESSED AIR

摘要

A method and apparatus for removing water from compressed air is disclosed. The method includes the steps of passing a stream of compressed air through a pressure swing adsorption (PSA) dryer. The dryer includes at least one vessel containing a desiccant material bound into pieces, for example tubes, using a polymer binder. The PSA dryer also has a control system for controlling the flow of the compressed air and switching between drying and purging modes. In particular the vessel and desiccant material contained therein are sized to produce a dew point suppression of less than 50° C.

1. A method of removing water from compressed air comprising, passing a stream of compressed air through a pressure swing adsorption dryer, the dryer including:
at least one vessel containing at least one desiccant material formed into desiccant members using a polymer binder; and at least one control system for controlling the flow of said compressed air and switching the flow of said compressed air between a drying mode and a purging mode, wherein said vessel and said desiccant material contained therein are sized to produce a dew point suppression of less than 50° C.
