Abstract
Abstract The disclosure describes a sorbing apparatus comprising at least one chamber having first and second ports and defining a fluid flow path between the first and second ports. The chamber includes a bed of sorbent particles which are disposed in the fluid flow path and the sorbent bed includes particles of clinoptilolite. The sorbing apparatus further comprises fluid control means for alternately directing fluid containing the substance through the bed of sorbent particles, whereby the bed of sorbent particles sorbs at least a portion of the substance from the fluid, and directing a purging fluid through the bed of sorbent particles, whereby the bed of sorbent particles is regenerated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
208 words
A sorbing apparatus for removing at least a portion of a substance from a gas containing the substance, the sorbing apparatus comprising an intake; an outlet; and exhaust; first and second sorbing chambers, each having first and second ports and defining a gas flow path therebetween and each including a bed having sorbent means disposed in the gas flow path for sorbing the substance from the gas, the sorbent means comprising non-immobilized particles of clinoptilolite; a first valve assembly interconnecting the intake, exhaust, and the first ports of the first and second sorbing chambers; a second arrangement for interconnecting the outlet and the second ports of the first and second sorbing chambers; and a controller coupled to at least the first valve assembly for alternately first directing gas from the intake through the first sorbing chamber to the outlet while channeling a portion of the outlet gas through the second sorbing chamber to the exhaust and directing gas from the intake through the second sorbing chamber to the outlet while channeling a portion of the outlet gas through the first sorbing chamber to the exhaust, whereby the sorbent bed in each sorbing chamber alternately sorbs the substance from the intake gas and is regenerated by the outlet gas.
Claim 2
Dependent Claim
208 words
A sorbing apparatus for removing at least a portion of a substance from a gas containing the substance, the sorbing apparatus comprising an intake; an outlet; and exhaust; first and second sorbing chambers, each having first and second ports and defining a gas flow path therebetween and each including a bed having sorbent means disposed in the gas flow path for sorbing the substance from the gas, the sorbent means comprising non-immobilized particles of clinoptilolite; a first valve assembly interconnecting the intake, exhaust, and the first ports of the first and second sorbing chambers; a second arrangement for interconnecting the outlet and the second ports of the first and second sorbing chambers; and a controller coupled to at least the first valve assembly for alternately first directing gas from the intake through the first sorbing chamber to the outlet while channeling a portion of the outlet gas through the second sorbing chamber to the exhaust and directing gas from the intake through the second sorbing chamber to the outlet while channeling a portion of the outlet gas through the first sorbing chamber to the exhaust, whereby the sorbent bed in each sorbing chamber alternately sorbs the substance from the intake gas and is regenerated by the outlet gas.
Claim 3
Dependent Claim
16 words
The sorbing apparatus of claim 1 wherein the sorbent means consists essentially of particles of clinoptilolite.
Claim 4
Dependent Claim
20 words
The sorbing apparatus of claim 1 wherein the sorbent means further includes particles of at least one additional sorbent material.
Claim 5
Dependent Claim
39 words
The sorbing apparatus of claim 3 wherein the sorbent means comprises at least first and second regions, the first region consisting essentially of particles of the additional sorbent material and the second region consisting essentially of particles of clinoptilolite.
Claim 6
Dependent Claim
61 words
The sorbing apparatus of claim 4 wherein the first port of the chamber comprises an inlet for the gas containing the substance and the second port comprises an outlet for the gas after at least a portion of the substance has been sorbed from the gas and wherein the second region is disposed nearer the second port than the first region.
Claim 7
Dependent Claim
29 words
The sorbing apparatus of claim 4 wherein the ratio of the volume of the additional sorbent material to the volume of the clinoptilolite is about 50/50, 25/75, or 10/90.
Claim 8
Dependent Claim
13 words
The sorbing apparatus of claim 3 wherein the additional sorbing material comprises alumina.
Claim 9
Dependent Claim
16 words
The sorbing apparatus of claim 1 wherein the sorbent particles are loosely loaded into the chamber.
Claim 10
Dependent Claim
16 words
The sorbing apparatus of claim 1, wherein the sorbent particles are compressively loaded into the chamber.
Claim 11
Dependent Claim
34 words
The sorbing apparatus of claim 1 wherein the sorbing apparatus includes means for containing the heat of adsorption and does not include a heater associated with the sorbent bed or with the outlet gas.
Claim 12
Dependent Claim
145 words
A sorbing apparatus for removing at least a portion of a substance from a gas containing the substance, the sorbing apparatus comprising an intake; an outlet; an exhaust; first and second cylindrical sorbing chambers, each including a bed having sorbent means for sorbing the substance from the gas, and first and second ports respectively communicating with the ends of the sorbent bed, the sorbent bed comprising non-immobilized particles of clinoptilolite; a first valve assembly interconnecting the intake, the exhaust, and the first ports of the first and second sorbing chambers; a second assembly interconnecting the outlet and the second ports of the first and second sorbing chambers; and a controller coupled to at least the first valve assembly for simultaneously directing intake gas through one sorbing chamber to the outlet and a portion of the outlet gas through the other sorbing chamber to the exhaust.
Claim 13
Dependent Claim
145 words
A sorbing apparatus for removing at least a portion of a substance from a gas containing the substance, the sorbing apparatus comprising an intake; an outlet; an exhaust; first and second cylindrical sorbing chambers, each including a bed having sorbent means for sorbing the substance from the gas, and first and second ports respectively communicating with the ends of the sorbent bed, the sorbent bed comprising non-immobilized particles of clinoptilolite; a first valve assembly interconnecting the intake, the exhaust, and the first ports of the first and second sorbing chambers; a second assembly interconnecting the outlet and the second ports of the first and second sorbing chambers; and a controller coupled to at least the first valve assembly for simultaneously directing intake gas through one sorbing chamber to the outlet and a portion of the outlet gas through the other sorbing chamber to the exhaust.
