Abstract
Abstract A continuous process for contacting components of a fluid mixture is described wherein at least one sorption zone is formed in a first separator. A sorbent material, which is in a continuous solid form, is passed through the sorption zone and then passed outwardly from the sorption zone. In the preferred process, a plurality of sorption zones are provided in the separator and a plurality of endless belts of sorbent material are passed through the sorption zones. The sorbent material is preferably a reversibly swellable material which swells as a result of contact with fluid in either the sorption or desorption zones and from which the nonsorbed fluid can be expressed during passage through the compression seal at the zone boundary.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A continuous process for adsorbing at least one component from a fluid mixture, which comprises: (a) forming at least one sorption zone in a first separator, said at least one sorption zone being bounded by a plurality of drive rollers and pairs of rollers, the rollers of each said pair being in rolling contact and forming a compression seal therebetween, said drive rollers positioned between said pairs of rollers and in rolling sealed contact therewith; (b) passing sorbent material, which is in a continuous solid form, through a first said compression seal between a first pair of said pairs of rollers into said at least one sorption zone; (c) passing the sorbent material through said at least one sorption zone and outwardly from said at least one sorption zone through a second said compression seal between a second pair of said pairs of rollers.
Claim 2
Dependent Claim
144 words
A continuous process for adsorbing at least one component from a fluid mixture, which comprises: (a) forming at least one sorption zone in a first separator, said at least one sorption zone being bounded by a plurality of drive rollers and pairs of rollers, the rollers of each said pair being in rolling contact and forming a compression seal therebetween, said drive rollers positioned between said pairs of rollers and in rolling sealed contact therewith; (b) passing sorbent material, which is in a continuous solid form, through a first said compression seal between a first pair of said pairs of rollers into said at least one sorption zone; (c) passing the sorbent material through said at least one sorption zone and outwardly from said at least one sorption zone through a second said compression seal between a second pair of said pairs of rollers.
Claim 3
Dependent Claim
13 words
The process of claim 1 wherein said sorbent material comprises an endless belt.
Claim 4
Dependent Claim
32 words
The process of claim 2 wherein a plurality of endless belts of sorbent material are provided and passed through said at least one sorption zone, thereby forming a plurality of sorption zones.
Claim 5
Dependent Claim
41 words
The process of claim 3 wherein each of said endless belts has opposite sides and wherein the belts are spaced away from one another in said sorption zones such that their opposite sides are brought into contact with the fluid mixture.
Claim 6
Dependent Claim
51 words
The process of claim 3, wherein all said belts which pass into said sorption zone through the same pair of rollers and out through the same pair of rollers are arranged in nested relation and are spaced apart from each other during a portion of their passage through said sorption zones.
