Abstract
Abstract A continuous process for separating components of a fluid mixture is disclosed which comprises forming a sorption zone and a desorption zone, said sorption and desorption zones being separated by a boundary of a sorbent material which continuously moves back and forth between the sorption and desorption zones, causing a fluid mixture to flow into the sorption zone wherein the conditions are such to promote sorption of one of the components of the mixture by the sorbent material, and creating conditions in the desorption zone such that the sorbed component will be desorbed when the sorbent material containing the sorbed component moves into the desorption zone. This sorption separation process is used in a network (including a linear series) of sorption/desorption units for separation of multiple components of fluid mixtures or for more complete separation of one component of a fluid mixture.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
179 words
A continuous process for separating components of a fluid mixture which comprises: a. Forming at least one sorption zone and at least one desorption zone in a first separator comprising at least one roller, at least one belt, or a combination of at least one roller and one belt, at least one of the belts and rollers having sorbent material thereon in engagement so that the sorbent material forms a boundary seal between the sorption and desorption zones, said sorption material continuously moving back and forth between the sorption and desorption zones, b. Causing a fluid mixture to flow into the sorption zone wherein the conditions are such to promote sorption of at least one of the components of the mixture by the sorbent material, c. Creating conditions in the desorption zone such that the sorbed component will be desorbed when the sorbent material containing the sorbed component moves into the desorption zone, and d. Conveying the product from at least one of said zones to at least one other separator and repeating steps a, b and c therein.
Claim 2
Dependent Claim

Causing a fluid mixture to flow into the sorption zone wherein the conditions are such to promote sorption of at least one of the components of the mixture by the sorbent material, c. Creating conditions in the desorption zone such that the sorbed component will be desorbed when the sorbent material containing the sorbed component moves into the desorption zone, and d. Conveying the product from at least one of said zones to at least one other separator and repeating steps a, b and c therein.
Claim 3
Dependent Claim
24 words
The process of claim 1 wherein the desorbed component forms a part of a second fluid mixture which is present in the desorption zone.
Claim 4
Dependent Claim
31 words
The process of claim 2 wherein the desorption zone is a reaction zone and the rate of reaction is controlled by the amount of desorbed component which enters the desorption zone.
Claim 5
Dependent Claim
43 words
The process of claim 1 wherein there is disposed between the sorption and desorption zones a number of rotating rollers which have the sorbent material at least on the surface thereof and which contact each other to form the sorption and desorption zones.
