Abstract
Abstract In a column for contacting a liquid with a vapor and having a plurality of vertically spaced apart vapor-liquid contacting trays therein, at least a portion of such trays are constructed such that a wall member is connected to the inlet surface of a contact tray and a perforated plate member is connected to such wall member in a manner to extend laterally inwardly above a part of the tray. The liquid flow path is directed over the wall member and across the perforated plate member to establish initial frothing of fluid and vapor prior to the distribution of the liquid flow over the remaining surface of the contact tray.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
In a column for contacting a liquid with a vapor and having vertically spaced vapor-liquid contacting trays, with at least one of such trays having a perforated portion for permitting gas flow therethrough, an imperforate liquid inlet portion, and downcomer means extending downwardly to terminate just above the inlet imperforate portion of the next lower tray, the improved tray construction which comprises, a wall member connected to and extending above said tray, said wall member separating the imperforate portion of said tray and the perforated portion thereof, whereby the liquid flow path is directed over said wall member, and a perforated plate member connected to the upper portion of said wall member and extending laterally inwardly across a portion of said column above a part of the perforated portion of said tray, the innermost edge of said perforated plate member being of convex shape with relation to said wall member to establish uniform flow across the perforated portion of said tray, whereby the liquid flow path is directed over said perforated plate member to establish initial frothing of fluid and vapor prior to the distribution of the liquid flow over the perforated portion of said tray.
Claim 2
Dependent Claim
196 words
In a column for contacting a liquid with a vapor and having vertically spaced vapor-liquid contacting trays, with at least one of such trays having a perforated portion for permitting gas flow therethrough, an imperforate liquid inlet portion, and downcomer means extending downwardly to terminate just above the inlet imperforate portion of the next lower tray, the improved tray construction which comprises, a wall member connected to and extending above said tray, said wall member separating the imperforate portion of said tray and the perforated portion thereof, whereby the liquid flow path is directed over said wall member, and a perforated plate member connected to the upper portion of said wall member and extending laterally inwardly across a portion of said column above a part of the perforated portion of said tray, the innermost edge of said perforated plate member being of convex shape with relation to said wall member to establish uniform flow across the perforated portion of said tray, whereby the liquid flow path is directed over said perforated plate member to establish initial frothing of fluid and vapor prior to the distribution of the liquid flow over the perforated portion of said tray.
Claim 3
Dependent Claim
13 words
The column according to claim 1 wherein said wall member is substantially imperforate.
Claim 4
Dependent Claim
23 words
The column according to claim 1, wherein said perforated plate member is spaced above and is substantially parallel to said vapor-liquid contacting tray.
Claim 5
Dependent Claim
13 words
The column according to clAim 1, wherein said wall member is substantially vertical.
Claim 6
Dependent Claim
187 words
In a column for contacting a liquid with a vapor and having vertically spaced vapor-liquid contacting trays, with at least one of such trays having a perforated portion for permitting gas flow therethrough, an imperforate liquid inlet portion, and downcomer means extending downwardly to terminate just above the inlet imperforate portion of the next lower tray, the improved tray construction which comprises, a wall member connected to and extending above said tray, said wall member separating the imperforate portion of said tray and the perforated portion thereof, whereby the liquid flow path is directed over said wall member, and a perforated plate member connected to the upper portion of said wall member and extending laterally inwardly across a portion of said column above a part of the perforated portion of said tray, the top of said perforated plate member being provided with directional vanes for improved distribution of liquid across said tray, whereby the liquid flow path is directed over said perforated plate member to establish initial frothing of fluid and vapor prior to the distribution of the liquid flow over the perforated portion of said tray.
Claim 7
Dependent Claim
187 words
