Abstract
Abstract The invention relates to an apparatus for promoting the separation and/or contact of two immiscible liquids, said apparatus comprising at least one pipe for feeding an emulsion of the two liquids to an assembly of tubes in each of which there is disposed, in the direction of its length and over at least a portion thereof, a bundle of fibers which are preferentially wettable by one of the two liquids, said assembly being connected to a decanter in which the two liquids separate, the decanter being provided with pipes for the discharge of each of the two liquids. The tubes are bounded by two walls, separated by a substantially constant distance, and by a corrugated element inserted between said walls and alternately in contact with each of them through its corrugations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
An apparatus for promoting the separation, contact, or contact and separation of two immiscible liquids, said apparatus comprising at least one pipe for feeding an emulsion of the two liquids to an assembly of tubes in each of which there is disposed, in the direction of its length and over at least a portion thereof, a bundle of fibers that is preferentially wettable by one of the two liquids, said assembly being connected to a decanter in which the two liquids separate, the decanter being equipped with pipes for the separate respective discharge of each of the two liquids, wherein the assembly of tubes is formed by spaced walls, separated by a substantially constant distance and by a corrugated element inserted between said walls and alternately in contact with each of said walls through its corrugations.
Claim 2
Independent Claim
136 words
An apparatus for promoting the separation, contact, or contact and separation of two immiscible liquids, said apparatus comprising at least one pipe for feeding an emulsion of the two liquids to an assembly of tubes in each of which there is disposed, in the direction of its length and over at least a portion thereof, a bundle of fibers that is preferentially wettable by one of the two liquids, said assembly being connected to a decanter in which the two liquids separate, the decanter being equipped with pipes for the separate respective discharge of each of the two liquids, wherein the assembly of tubes is formed by spaced walls, separated by a substantially constant distance and by a corrugated element inserted between said walls and alternately in contact with each of said walls through its corrugations.
Claim 3
Dependent Claim
19 words
An apparatus as defined in claim 1 wherein said spaced walls are formed by a plurality of concentric walls.
Claim 4
Dependent Claim
22 words
An apparatus as defined in claim 1 wherein said spaced walls are formed by a single wall of wound into a helix.
Claim 5
Independent Claim
191 words
An apparatus for the desaltimg of a hydrocarbon feedstock, comprising a desalter, at least one pipe for feeding an emulsion of water and the hydrocarbon feedstock to the desalter, at least one pipe for discharging the salt-water phase separated in the desalter, and at least one pipe for discharging the hydrocarbon phase from the desalter, said apparatus comprising at least one enclosure which is disposed in one or both of the feed pipe for the emulsion of water and hydrocarbon feedstock ahead of the desalter or in the discharge pipe for the hydrocarbon phase ahead of a decanter provided with discharge pipes for the water and the hydrocarbon phase, wherein said enclosure contains an assembly of tubes in each of which tube there is disposed, in the direction of its length and over at least a portion thereof, a bundle of fibers which are preferentially wettable by one of water or the hydrocarbon feedstock, wherein the assembly of tubes is formed by spaced walls, separated by a substantially constant distance and by a corrugated element inserted between said walls and alternately in contact with each of said walls through its corrugations.
Claim 6
Independent Claim
191 words
An apparatus for the desaltimg of a hydrocarbon feedstock, comprising a desalter, at least one pipe for feeding an emulsion of water and the hydrocarbon feedstock to the desalter, at least one pipe for discharging the salt-water phase separated in the desalter, and at least one pipe for discharging the hydrocarbon phase from the desalter, said apparatus comprising at least one enclosure which is disposed in one or both of the feed pipe for the emulsion of water and hydrocarbon feedstock ahead of the desalter or in the discharge pipe for the hydrocarbon phase ahead of a decanter provided with discharge pipes for the water and the hydrocarbon phase, wherein said enclosure contains an assembly of tubes in each of which tube there is disposed, in the direction of its length and over at least a portion thereof, a bundle of fibers which are preferentially wettable by one of water or the hydrocarbon feedstock, wherein the assembly of tubes is formed by spaced walls, separated by a substantially constant distance and by a corrugated element inserted between said walls and alternately in contact with each of said walls through its corrugations.
Claim 7
Dependent Claim
19 words
An apparatus as defined in claim 4 wherein said spaced walls are formed by a plurality of concentric walls.
Claim 8
Dependent Claim
21 words
An apparatus as defined in claim 4 wherein said spaced walls are formed by a single wall wound into a helix.
Claim 9
Dependent Claim
164 words
A process for the desalting of a hydrocarbon feedstock, comprising feeding an emulsion of water and the hydrocarbon feedstock to at least one desalter, and treating at least one of the emulsion or the hydrocarbon feedstock discharged from the desalter by means of an apparatus comprising at least one pipe for feeding an emulsion of the two liquids to an assembly of tubes in each of which there is disposed, in the direction of its length and over at least a portion thereof, a bundle of fibers that is preferentially wettable by one of the two liquids, said assembly being connected to a decanter in which the two liquids separate, the decanter being equipped with pipes for the separate respective discharge of each of the two liquids, wherein the assembly of tubes is formed by spaced walls, separated by a substantially constant distance and by a corrugated element inserted between said walls and alternately in contact with each of said walls through its corrugations.
Claim 10
Dependent Claim
164 words
A process for the desalting of a hydrocarbon feedstock, comprising feeding an emulsion of water and the hydrocarbon feedstock to at least one desalter, and treating at least one of the emulsion or the hydrocarbon feedstock discharged from the desalter by means of an apparatus comprising at least one pipe for feeding an emulsion of the two liquids to an assembly of tubes in each of which there is disposed, in the direction of its length and over at least a portion thereof, a bundle of fibers that is preferentially wettable by one of the two liquids, said assembly being connected to a decanter in which the two liquids separate, the decanter being equipped with pipes for the separate respective discharge of each of the two liquids, wherein the assembly of tubes is formed by spaced walls, separated by a substantially constant distance and by a corrugated element inserted between said walls and alternately in contact with each of said walls through its corrugations.
