US Patent:

58141308, Sep 29, 1998

Filed:

Sep 27, 1996

Appl. No.:

8/722584

Inventors:

Norberto O. Lemcoff - Livingston NJ
Mario A. Fronzoni - East Brunswick NJ
Michael E. Garrett - Woking, GB2
Brian C. Green - Brockham, GB2

Assignee:

The BOC Group, Inc. - New Providence NJ

International Classification:

B01D 53047

US Classification:

95 96

Abstract:

A rotary valve assembly which includes of a pair of valve parts with flat faces which, when pressed together and rotated, provide valving action between various ports incorporated in one of the valve parts. The first valve part contains two circular arrays of through openings, each of which is connected to a conduit. The second valve part contains several passages which provide communication between various openings of the first valve part and valve ports located in the second valve part. The second valve part also contains one or more passages which provide communication between two openings of one array of openings and one opening of the other array of openings. The valve assembly can be effectively used to automate operation of a gas or liquid adsorption system comprising two or more adsorption vessels, the number of vessels being equivalent to the total number of openings in either array. Use of the valve assembly in an adsorption system eliminates the need for many of the valves required in conventional multivessel adsorption systems.
