Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
Apparatus for contacting gas and liquid comprising a vessel having fluid inlet means and fluid outlet means, and a horizontal tray arranged in the vessel and provided with a contacting means, wherein the contacting means comprises an open-ended vertical tube in which contacting material is arranged and in which swirl imparting means are arranged above the contacting material, first conduit means allowing fluid communication between the space above the horizontal tray and the interior of the vertical tube below the contacting material, and second conduit means allowing fluid communication between the interior of the vertical tube above the swirl imparting means and the space below the horizontal tray.
Claim 2
Dependent Claim
108 words
Apparatus for contacting gas and liquid comprising a vessel having fluid inlet means and fluid outlet means, and a horizontal tray arranged in the vessel and provided with a contacting means, wherein the contacting means comprises an open-ended vertical tube in which contacting material is arranged and in which swirl imparting means are arranged above the contacting material, first conduit means allowing fluid communication between the space above the horizontal tray and the interior of the vertical tube below the contacting material, and second conduit means allowing fluid communication between the interior of the vertical tube above the swirl imparting means and the space below the horizontal tray.
Claim 3
Dependent Claim
19 words
Apparatus as claimed in claim 1, wherein the tray comprises a plurality of contacting means distributed over the tray.
Claim 4
Dependent Claim
21 words
Apparatus as claimed in claim 1 or 2, wherein the vessel comprises a two or more axially spaced apart horizontal trays.
Claim 5
Dependent Claim
21 words
Apparatus as claimed in any one of the claims 1-3, wherein the first conduit means comprises at least one open-ended tube.
Claim 6
Dependent Claim
76 words
Apparatus as claimed in any one of the claims 1-4, wherein the second conduit means comprises a space between the outer side of the wall of that vertical tube and the inner side of the wall of a tube arranged externally around the vertical tube, the upper end of the space communicating with the interior of the vertical tube above the swirl imparting means and the lower end having an outlet opening below the horizontal tray.
Claim 7
Dependent Claim
131 words
Method of contacting gas and liquid in a vessel in which there is arranged a horizontal tray provided with contacting means, comprising introducing gas into the vessel below the horizontal tray, introducing liquid into the vessel above the horizontal tray, passing liquid from above the horizontal tray into the interior of an open-ended vertical tube pertaining to the contacting means below contacting material arranged in the vertical tube, passing liquid and gas upwardly through the contacting material, passing liquid and gas via swirl imparting means arranged in the vertical tube so as to separate liquid and gas, passing liquid from the upper part of the vertical tube to below the horizontal tray, removing gas from the vessel above the horizontal tray and removing liquid from the vessel below the horizontal tray.
Claim 8
Dependent Claim
131 words
Method of contacting gas and liquid in a vessel in which there is arranged a horizontal tray provided with contacting means, comprising introducing gas into the vessel below the horizontal tray, introducing liquid into the vessel above the horizontal tray, passing liquid from above the horizontal tray into the interior of an open-ended vertical tube pertaining to the contacting means below contacting material arranged in the vertical tube, passing liquid and gas upwardly through the contacting material, passing liquid and gas via swirl imparting means arranged in the vertical tube so as to separate liquid and gas, passing liquid from the upper part of the vertical tube to below the horizontal tray, removing gas from the vessel above the horizontal tray and removing liquid from the vessel below the horizontal tray.
Claim 9
Dependent Claim
145 words
Process for the removal of H₂S from a sour H₂S-containing gaseous mixture comprising introducing the gaseous mixture into a vessel below a horizontal tray provided with contacting means which tray is arranged in the vessel, introducing lean and regeneratable absorbent into the vessel above the horizontal tray, passing absorbent from above the horizontal tray into the interior of an open-ended vertical tube pertaining to the contacting means below contacting material arranged in the vertical tube, passing absorbent and gaseous mixture upwardly through the contacting material, passing absorbent and gaseous mixture via swirl imparting means arranged in the vertical tube so as to separate purified gas and loaded absorbent, passing loaded absorbent from the upper part of the vertical tube to below the horizontal tray, removing purified gas from the vessel above the horizontal tray and removing loaded absorbent from the vessel below the horizontal tray.
Claim 10
Dependent Claim
145 words
Process for the removal of H₂S from a sour H₂S-containing gaseous mixture comprising introducing the gaseous mixture into a vessel below a horizontal tray provided with contacting means which tray is arranged in the vessel, introducing lean and regeneratable absorbent into the vessel above the horizontal tray, passing absorbent from above the horizontal tray into the interior of an open-ended vertical tube pertaining to the contacting means below contacting material arranged in the vertical tube, passing absorbent and gaseous mixture upwardly through the contacting material, passing absorbent and gaseous mixture via swirl imparting means arranged in the vertical tube so as to separate purified gas and loaded absorbent, passing loaded absorbent from the upper part of the vertical tube to below the horizontal tray, removing purified gas from the vessel above the horizontal tray and removing loaded absorbent from the vessel below the horizontal tray.
