Abstract
Abstract This invention relates to a process for magnetically stabilizing the operation of contactor columns containing immiscible fluids passing in dispersed countercurrent flow. The process operates by including, in an appropriate fluid phase, a magnetizable component in an amount which does not substantially change the nature of the liquid in that phase and, further, imposing upon at least a portion of the column containing dispersed phases, a magnetic field sufficient to result in substantially diminished radial mixing of the phase containing the magnetizable substance and diminished coalescence of the dispersed phase. The phase containing the magnetizable component passes through the stabilized zone in substantial plug flow.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
83 words
A method for stabilizing a contacting zone wherein a first and a second fluid, which are substantially immiscible, are contacted in said zone, comprising the steps of: adding a sufficient amount of a magnetizable material to one of said first or second fluids; dispersing one of said fluids into the other; maintaining a magnetic field about at least a portion of the contacting zone, said magnetic field having sufficient strength to prevent substantial axial or radial mixing of the first or second fluid.
Claim 2
Independent Claim
83 words
A method for stabilizing a contacting zone wherein a first and a second fluid, which are substantially immiscible, are contacted in said zone, comprising the steps of: adding a sufficient amount of a magnetizable material to one of said first or second fluids; dispersing one of said fluids into the other; maintaining a magnetic field about at least a portion of the contacting zone, said magnetic field having sufficient strength to prevent substantial axial or radial mixing of the first or second fluid.
Claim 3
Dependent Claim
25 words
The process of claim 1 wherein the first fluid is a gas and the second fluid is a liquid, said liquid containing the magnetizable material.
Claim 4
Dependent Claim
13 words
The process of claim 1 wherein the first and second fluids are liquid.
Claim 5
Dependent Claim
14 words
The process of claim 1 wherein heat is transferred between first and second fluids.
Claim 6
Dependent Claim
15 words
The process of claim 1 wherein mass is transferred between said first and second fluids.
Claim 7
Dependent Claim
15 words
The process of claim 1 wherein a chemical reaction takes place within the contacting zone.
Claim 8
Dependent Claim
12 words
The process of claim 1 wherein the magnetizable material comprises a ferrofluid.
Claim 9
Dependent Claim
27 words
The process of claim 1 wherein the magnetizable material is added to one of said first or second fluids in the form of an added third phase.
Claim 10
Dependent Claim
17 words
The process of claim 1 wherein said first and second fluids flow cocurrently within the contacting zone.
Claim 11
Dependent Claim
15 words
The process of claim 9 wherein the dispersed phase is covered with a liquid membrane.
Claim 12
Dependent Claim
17 words
The process of claim 1 wherein said first and second fluids flow countercurrently within the contacting zone.
Claim 13
Dependent Claim
15 words
The process of claim 11 wherein the dispersed phase is covered with a liquid membrane.
Claim 14
Dependent Claim
11 words
The process of claim 1 wherein the magnetizable material comprises macroparticles.
Claim 15
Dependent Claim
26 words
The process of claim 13 wherein the macroparticles comprise finely divided iron, 400 series stainless steel, magnetite, nickel, cobalt or alloys of nickel, cobalt, or iron.
