Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
200 words
A system for condensing a gas comprising a housing having a gas inlet into the top wall of the housing, at least one vertical column of vertically spaced separate tube bundles, said tube bundles being separated from the longitudinal walls of the housing defining gaps between the longitudinal walls and the sides of the tube bundles so that gas entering through said inlet will flow through the gaps as well as into the space between the tube bundles, a separate valved water conduit connected to each tube bundle, a condensation collection tray located beneath each tube bundle which is above the lowermost tube bundle, conduit means at least partially disposed in one of said gaps for flowing condensate from each tray into the bottom of the housing by way of said one gap, a condensate collection means below the lowermost tube bundle for receiving condensate from each tray, and the separate tube bundles being vertically aligned with the width of the tube bundles being progressively larger from the top tube bundle to the lowermost tube bundle whereby the gas condensing capacity of said bundles increases and said gaps progressively decrease from the top tube bundle to the lowermost tube bundle.
Claim 2
Independent Claim
200 words
A system for condensing a gas comprising a housing having a gas inlet into the top wall of the housing, at least one vertical column of vertically spaced separate tube bundles, said tube bundles being separated from the longitudinal walls of the housing defining gaps between the longitudinal walls and the sides of the tube bundles so that gas entering through said inlet will flow through the gaps as well as into the space between the tube bundles, a separate valved water conduit connected to each tube bundle, a condensation collection tray located beneath each tube bundle which is above the lowermost tube bundle, conduit means at least partially disposed in one of said gaps for flowing condensate from each tray into the bottom of the housing by way of said one gap, a condensate collection means below the lowermost tube bundle for receiving condensate from each tray, and the separate tube bundles being vertically aligned with the width of the tube bundles being progressively larger from the top tube bundle to the lowermost tube bundle whereby the gas condensing capacity of said bundles increases and said gaps progressively decrease from the top tube bundle to the lowermost tube bundle.
Claim 3
Dependent Claim
60 words
A system in accordance with claim 1 wherein each tray is horizontally disposed, said conduit means including a plurality of horizontally disposed conduits, each tray communicating with one end of one of said horizontally disposed conduits, the other end of each conduit terminating in said one gap for discharge of condensate through said one gap to said condensate collection means.
Claim 4
Dependent Claim
105 words
A system in accordance with claim 1 wherein two such vertical columns of tube bundles are disposed side by side within said housing and similarly spaced from the side walls of said housing, said columns being spaced from one another so as to define a downwardly extending space which progressively decreases from top to bottom whereby gas entering from said inlet will flow between the tube bundles of said columns, and a dome on said housing between said inlet and the portion of the housing containing said columns, the transverse dimensions of said dome progressively increase in a direction from said inlet towards said columns.
Claim 5
Dependent Claim
19 words
A system in accordance with claim 1 wherein there are at least three tube bundles in said vertical column.
Claim 6
Dependent Claim
32 words
A system in accordance with claim 1 including a discrete valved conduit extending through a wall of said housing and communicating with each tray for selective removal of condensate from the trays.
