Abstract
Abstract Pure non-combustible liquid is reclaimed from an impure liquid source containing dissolved and non-soluble contaminants, by vaporizing the liquid and volatile contaminants and subjecting the vapors directly to hot gases of combustion of a combustible fuel. The non-combustible solids contaminants are separated by momentum differences, the non-condensible gases are scrubbed clean and exhausted, and the condensible liquid is recovered in pure form by condensation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
31 words
THE METHOD OF RECLAIMING CONDENSIBLE, NON-COMBUSTIBLE LIQUID CONTAINING IMPURITIES, COMPRISING A. VAPORIZING THE LIQUID, B. MIXING THE VAPORIZED LIQUID AND IMPURITIES WITH THE HOT GASES OF COMBUSTION OF A COMBUSTIBLE FUEL,
Claim 2
Dependent Claim
15 words
The method of claim 1 wherein the hot gases of combustion include the flame thereto.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein the hot gases of combustion are of the oxidizing type to effect ignition of the combustible component of impurities.
Claim 4
Dependent Claim
17 words
The method of claim 1 wherein the hot gases of combustion are utilized to vaporize the liquid.
Claim 5
Dependent Claim
44 words
The method of claim 1 wherein the separation by momentum differences is achieved by centrifugal action by causing the hot gases of combustion to rotate in a confined space, whereby to centrifuge the solids component radially outward to the boundary of said confined space.
Claim 6
Dependent Claim
42 words
The method of claim 1 wherein the separation by momentum differences is achieved by gravitation by causing the hot gases of combustion to move linearly through a confined space whereby to cause the solids componenT to gravitate downward in said confined space.
