Abstract
Abstract A carbon dioxide absorber assembly is provided in which the passing gas stream traverses at least one layer of a chemical composition which effectively removes carbon dioxide therefrom by chemical reaction or physical absorption. The layer or layers of said chemical composition is mechanically supplied to and withdrawn from the absorption zone in transverse direction to said gas stream.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
A device for removing carbon dioxide from a gas stream comprising a sealed chamber with an inlet port for said gas stream, an outlet port for said gas stream, at least one carbon dioxide absorption zone designed to have a defined, sealed passage way and suitable mechanical forwarding means continuously supplying at least one flexible, porous matrix material to and through said absorption zone, supporting or carrying a carbon dioxide absorbing material to said absorption zone essentially in perpendicular direction to said gas stream ports from a (supply) storage source which continuously supplies said porous matrix and absorbing material to said absorption zone through an inlet port located on one side of said chamber, to and through said chamber and removed through an outlet port located on the opposite side of said chamber, said storage source being sealed to said sealed chamber in such a way that all of said gas stream must pass at least once through said carbon dioxide absorbing material while said absorbing material is drawn continuously through said sealed passage way and through said absorption zone and removed from said absorption zone by the suitable mechanical means.
Claim 2
Independent Claim
191 words
A device for removing carbon dioxide from a gas stream comprising a sealed chamber with an inlet port for said gas stream, an outlet port for said gas stream, at least one carbon dioxide absorption zone designed to have a defined, sealed passage way and suitable mechanical forwarding means continuously supplying at least one flexible, porous matrix material to and through said absorption zone, supporting or carrying a carbon dioxide absorbing material to said absorption zone essentially in perpendicular direction to said gas stream ports from a (supply) storage source which continuously supplies said porous matrix and absorbing material to said absorption zone through an inlet port located on one side of said chamber, to and through said chamber and removed through an outlet port located on the opposite side of said chamber, said storage source being sealed to said sealed chamber in such a way that all of said gas stream must pass at least once through said carbon dioxide absorbing material while said absorbing material is drawn continuously through said sealed passage way and through said absorption zone and removed from said absorption zone by the suitable mechanical means.
Claim 3
Dependent Claim
29 words
The device of claim 1 which also contains a supplemental gas inlet port through which additional fresh or other carbon dioxide-free gas can be supplied to the absorption chamber.
Claim 4
Dependent Claim
75 words
The device of claim 1 wherein the gas stream chamber is U-shaped and the gas flows through side-by-side absorption zones fed by the same supply source for carbon dioxide absorbing material and whereby the gas prior to reaching the outlet port passes through a second absorption zone supplied with fresh carbon dioxide absorbing material and said absorbing material subsequently passes through a first absorption zone located between the inlet port and said second absorption zone.
Claim 5
Dependent Claim
32 words
The device of claim 1 wherein said matrix is a woven or non-woven substrate containing dispersed therein said carbon dioxide absorbing material, said substrate offering substantially no resistance to said gas stream.
Claim 6
Dependent Claim
33 words
The device of claim 1 wherein means are provided for exposing the gas stream to a carbon dioxide absorbant composition which offers substantially no resistance or uniformly low resistance to said gas stream.
