Abstract
Abstract The invention relates to a vaporization and condensation process for the fractionation of mixtures by continuously heating, in a circulation circuit, a clean heat transfer gas which is subsequently injected into a mixture to be fractionated (16), of which at least one liquid fraction, which has separated off by vaporization, is condensed and collected while the heat transfer gas returns to the circulation circuit.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
157 words
An apparatus for the fractionation of a mixture comprising at least one liquid volatile fraction, which comprises a vaporization chamber, consisting of a cell equipped with a feed device for introducing a mixture to be fractionated, and a device for discharging the residue, the chamber being surmounted by a gas column, a circulation circuit, comprising a fan whose inlet communicates with the upper zone of the vaporization chamber, said fan drawing a subfraction of the vaporized fraction which is formed in the vaporization chamber and feeding it into an outlet line, a heating device, said outlet line passing through said heating device which superheats said subfraction and carrying at its discharge end a distributor which brings the said superheated subfraction of the vaporized fraction into contact with the contents of said cell, and a condenser connected to the said gas outlet column for condensation and collection of the fraction which has been vaporized in the vaporization chamber.
Claim 2
Independent Claim
157 words
An apparatus for the fractionation of a mixture comprising at least one liquid volatile fraction, which comprises a vaporization chamber, consisting of a cell equipped with a feed device for introducing a mixture to be fractionated, and a device for discharging the residue, the chamber being surmounted by a gas column, a circulation circuit, comprising a fan whose inlet communicates with the upper zone of the vaporization chamber, said fan drawing a subfraction of the vaporized fraction which is formed in the vaporization chamber and feeding it into an outlet line, a heating device, said outlet line passing through said heating device which superheats said subfraction and carrying at its discharge end a distributor which brings the said superheated subfraction of the vaporized fraction into contact with the contents of said cell, and a condenser connected to the said gas outlet column for condensation and collection of the fraction which has been vaporized in the vaporization chamber.
Claim 3
Dependent Claim
24 words
An apparatus according to claim 1, further including a mist separator located upstream of the said condenser and upstream of the said fan inlet.
Claim 4
Dependent Claim
20 words
An apparatus according to claim 1 wherein the whole of the said circulation circuit is located inside the vaporization chamber.
Claim 5
Dependent Claim
20 words
An apparatus according to claim 2 wherein the whole of the said circulation circuit is located inside the vaporization chamber.
Claim 6
Dependent Claim
17 words
An apparatus according to claim 1 wherein the said heating device is located outside the vaporization chamber.
Claim 7
Dependent Claim
17 words
An apparatus according to claim 2 wherein the said heating device is located outside the vaporization chamber.
Claim 8
Dependent Claim
20 words
An apparatus according to claim 1 wherein the vaporization chamber is heat-insulated by one or more layers of heat-insulating material.
Claim 9
Dependent Claim
20 words
An apparatus according to claim 2 wherein the vaporization chamber is heat-insulated by one or more layers of heat-insulating material.
Claim 10
Dependent Claim
33 words
An apparatus according to claim 8, wherein the said heating device is a steam heat exchanger which receives live steam through one line and returns colder steam and/or condensation water through another line.
Claim 11
Dependent Claim
38 words
An apparatus according to claim 9, wherein the said distributor is a nozzle manifold which delivers the said superheated part of the vaporized fraction with sufficient impulse to cause movements in the said contents of the said cell.
Claim 12
Dependent Claim
24 words
An apparatus according to claim 10, further including a device which maintains a constant pressure comprising a vacuum pump connected to the said condenser.
