Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
107 words
A method for separating a flowing mixture of immiscible fluids of different density in which a higher density fluid phase is dispersed within a lower density fluid phase comprising passing the mixture through an inertial separator having an N D value of 50 or below under conditions of non-atomizing flow such that the coordinates of the gas phase Froude coefficient and (1 + 30M) 0 .5 times the ratio of the liquid phase Froude coefficient to the gas phase Froude coefficient of the fluid mixture at the separator inlet lie within the enclosed area defined by points A, B, C, D and E in FIG. 1 hereto.
Claim 2
Independent Claim
107 words
A method for separating a flowing mixture of immiscible fluids of different density in which a higher density fluid phase is dispersed within a lower density fluid phase comprising passing the mixture through an inertial separator having an N D value of 50 or below under conditions of non-atomizing flow such that the coordinates of the gas phase Froude coefficient and (1 + 30M) 0 .5 times the ratio of the liquid phase Froude coefficient to the gas phase Froude coefficient of the fluid mixture at the separator inlet lie within the enclosed area defined by points A, B, C, D and E in FIG. 1 hereto.
Claim 3
Dependent Claim
27 words
The method of claim 1 in which the ratio of the density of the higher density phase to the lower density phase is at least about 2.
Claim 4
Dependent Claim
22 words
The method of claim 1 in which the mixture of immiscible fluids is comprised of more than one higher density fluid phase.
Claim 5
Dependent Claim
17 words
The method of claim 1 in which the higher density fluid phase contains particulate solids dispersed therein.
Claim 6
Dependent Claim
34 words
The method of claim 1 in which the higher density phase is atomized and the addition of higher density fluid to the mixture is required to place the higher density phase in non-atomized form.
Claim 7
Dependent Claim
30 words
The method of claim 5 in which addition of higher density fluid is accomplished by passing the mixture through a non-atomizing scrubber discharging into the inlet of the inertial separator.
Claim 8
Dependent Claim
14 words
The method of claim 6 in which the non-atomizing scrubber is a reverse-jet scrubber.
Claim 9
Dependent Claim
17 words
The method of claim 7 in which the lower density fluid phase contains particulate solids dispersed therein.
Claim 10
Dependent Claim
13 words
The method claim 8 in which the entrained particulate solids are coal dust.
Claim 11
Dependent Claim
15 words
The method of claim 6 in which the non-atomizing scrubber is a flooded mesh scrubber.
Claim 12
Dependent Claim
34 words
The method of claim 1 in which the higher density phase is atomized and the removal of higher density fluid from the mixture is required to place the higher density phase in non-atomized form.
Claim 13
Dependent Claim
37 words
The method of claim 11 in which removal of higher density fluid is accomplished by passing the mixture through a knockout trap, the less dense fluid outlet of which discharges into the inlet of the inertial separator.
Claim 14
Dependent Claim
26 words
The method of claim 1 in which the higher density phase is atomized and must be coalesced to place the higher density phase in non-atomized form.
Claim 15
Dependent Claim
32 words
The method of claim 13 in which the higher density phase is coalesced to non-atomized form by passing the mixture through a non-atomizing scrubber discharging into the inlet of the inertial separator.
Claim 16
Dependent Claim
19 words
The method of claim 14 in which the scrubbing medium is water and the lower density fluid is air.
