Abstract
Abstract A system in which an incoming fluid stream containing a polar impurity is separated into a stream rich in impurity and a stream weak in the impurity. A hot fluid stream is cooled. A solid sorbent system extracts the impurity from the cool zone and returns it to the hot zone. A side stream carries off impurity which accumulates between the zones.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
111 words
An adsorption system for removing an impurity from a hot fluid stream, comprising: (a) a cooler placed in the stream, (b) a first body of sorbent placed in the stream, upstream of the cooler, (c) a second body of sorbent in the stream, downstream of the cooler, (d) first means for exchanging the positions of the bodies relative to the stream, the means including a drum rotatable on an axis, the drum being divided into a plurality of flow paths which pass through its geometric axis and through which the stream passes, and (e) a slip stream means for extracting a portion of the stream from between the bodies of sorbent.
Claim 2
Dependent Claim
111 words
An adsorption system for removing an impurity from a hot fluid stream, comprising: (a) a cooler placed in the stream, (b) a first body of sorbent placed in the stream, upstream of the cooler, (c) a second body of sorbent in the stream, downstream of the cooler, (d) first means for exchanging the positions of the bodies relative to the stream, the means including a drum rotatable on an axis, the drum being divided into a plurality of flow paths which pass through its geometric axis and through which the stream passes, and (e) a slip stream means for extracting a portion of the stream from between the bodies of sorbent.
Claim 3
Dependent Claim
16 words
A system as recited in claim 1, wherein the paths are generally perpendicular to the axis.
Claim 4
Dependent Claim
13 words
A system as recited in claim 1, wherein the drum carries the sorbent.
Claim 5
Dependent Claim
57 words
A system as recited in claim 1, wherein the drum is enclosed in a shell and driving means is provided to rotate the drum with respect to the shell in a continuous preselected pattern, the drum having a plurality of separated, axially spaced path levels, at least two of the levels controlling separate parts of the stream.
Claim 6
Dependent Claim
65 words
A system as recited in claim 4, wherein the shell has levels corresponding to those of the drum, at least one level of the shell having a first set of at least two openings and a second set of at least two openings, and rotation of the drum causes simultaneous communication between all of the openings in each set but never communication between the sets.
Claim 7
Dependent Claim
91 words
An adsorption system for removing an impurity from a fluid stream, comprising: (a) a first body of sorbent, (b) a second body of sorbent, (c) a control means which controls the flow of streams through the bodies and controls activations of the bodies, the means including a drum rotatable on an axis, the drum being divided into a plurality of flow paths which pass completely through the drum along a line through and perpendicular to the geometric axis of the drum, the stream passing through the paths from time to time.
Claim 8
Dependent Claim
91 words
An adsorption system for removing an impurity from a fluid stream, comprising: (a) a first body of sorbent, (b) a second body of sorbent, (c) a control means which controls the flow of streams through the bodies and controls activations of the bodies, the means including a drum rotatable on an axis, the drum being divided into a plurality of flow paths which pass completely through the drum along a line through and perpendicular to the geometric axis of the drum, the stream passing through the paths from time to time.
Claim 9
Dependent Claim
13 words
A system as recited in claim 6, wherein the drum carries the sorbent.
Claim 10
Dependent Claim
57 words
A system as recited in claim 6, wherein the drum is enclosed in a shell and driving means is provided to rotate the drum with respect to the shell in a continuous preselected pattern, the drum having a plurality of separated, axially spaced path levels, at least two of the levels controlling separate parts of the stream.
Claim 11
Dependent Claim
65 words
A system as recited in claim 8, wherein the shell has levels corresponding to those of the drum, at least one level of the shell having a first set of at least two openings and a second set of at least two openings, and rotation of the drum causes simultaneous communication between all of the openings in each set but never communication between the sets.
