Filed:

Jan 21, 1997

Appl. No.:

8/784555

Inventors:

Norberto O. Lemcoff - Livingston NJ
Mario A. Fronzoni - East Brunswick NJ

Assignee:

The BOC Group, Inc. - New Providence NJ

International Classification:

B01D 53047

US Classification:

95 96

Abstract:

A rotary valve system which includes of a pair of valve assemblies each of which has valve parts with flat faces which, when pressed together and rotated, provide valving action between various ports incorporated in one valve part of each assembly. The first valve part of each assembly contains a circular array of through openings, each of which is connected to a conduit. The second valve part of each assembly contains several passages which provide communication between various openings of the first valve part and valve apertures located in the second valve part of each assembly. The second valve part of each assembly also contains one or more passages which provide communication between members of one or the other array of openings. The valve system 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.
