Independent Claim
19 words
A column according to claim 1 wherein said opening is a slit extending substantially the length of said conduit.
Claim 2
Dependent Claim
27 words
A column according to claim 2 wherein said opening is a plurality of holes, said plurality extending over a substantial portion of the length of said conduit.
Claim 3
Dependent Claim
46 words
A column according to claim 1 wherein said redistributor is provided with a plurality of closed fins, said fins being located above said conduit and said hollow fins and adjacent thereto, spaces between said closed fins extending vertically and constituting at least one gas distribution passway.
Claim 4
Dependent Claim
20 words
A column according to claim 3 wherein each of said holes is provided with a tongue depending from its bottom.
Claim 5
Dependent Claim
15 words
A column according to claim 5 wherein said tongue is directed inwardly of said column.
Claim 6
Dependent Claim
35 words
A column according to claim 1 wherein the area of said gas distribution passway is less than the horizontal cross-sectional area of said contact part, whereby the linear velocity of the gas and liquid increases.
Claim 7
Dependent Claim
31 words
A column according to claim wherein a liquid distributor is provided between said liquid inlet and said upper contact part, said distributor communicating with said liquid inlet and said upper part.
Claim 8
Dependent Claim
16 words
A column according to claim 8 wherein said liquid distributor is the same as said redistributor.
Claim 9
Dependent Claim
173 words
A rectification column having a gas inlet adjacent its lower end, a gas outlet adjacent its upper end, a liquid inlet adjacent said upper end and a liquid outlet adjacent said lower end, a lower gas-liquid contact part adjacent said gas inlet and said liquid outlet, an upper gas-liquid contact part adjacent said liquid inlet and said gas outlet, said gas inlet and said liquid outlet in communication with said lower part, said liquid inlet and said gas outlet in communication with said upper part, a gas-liquid redistributor between said upper and said lower parts in communication therewith, said redistributor comprising a plurality of fins having hollow bores, said bores extending vertically and being open at both ends, whereby gas passways are formed in said bores and between adjacent fins, a liquid distribution conduit extending horizontally substantially alongside said fins, at least one opening extending over a substantial portion of the length of said conduit, whereby separation of downflow liquid from upflow gas and high efficiency contact between gas and liquid is obtained.
Claim 10
Dependent Claim
143 words
In a gas-liquid contact apparatus comprising a gas-liquid contact part accommodating metal fin material, a liquid distributor provided above the gas-liquid contact part, a gas distributor provided below the gas-liquid contact part, a liquid inlet provided in connection with the liquid distributor, a liquid outlet provided at the lowest position of the apparatus, a gas inlet provided in connection with the gas distributor, and a gas outlet provided with the highest position of the apparatus, the improvement comprising metal fin material, said fin material having (1) corrugated fins brazed either to each other or to intervening spacer plates and (2) at least oNe gas-liquid redistributor comprising corrugated fins forming gas passage means and brazed onto the side of a liquid redistribution trough having a perforated bottom and being provided at a position lower than the liquid distributor and higher than the gas distributor.
Claim 11
Dependent Claim
