Waste water processing system

Claim 1

IN A PROCESS UTILIZING STEAM AND PRODUCING A WASTE STREAM CONTAINING WATER AND COMBUSTIBLE VOLATILE CONTAMINATING MATERIALS THE IMPROVED METHOD OF DISPOSING OF SAID WASTE STREAM WHICH COMPRISES PASSING SAID WASTE STREAM TO THE UPPER PORTION OF A VAPOR LIQUID CONTACTING COLUMN, PASSING A FIRST VAPOR STREAM OF STEAM AND CONTAMINATING MATERIALS IN LOWER CONCENTRATION THEN IN SAID WASTE STREAM TO THE LOWER PORTION OF SAID COLUMN CONTACTING SAID WASTE STREAM AND FIRST VAPOR STREAM IN COUNTERCURRENT FLOW IN SAID COLUMN TO PRODUCE A SECOND VAPOR OVERHEAD STREAM OF STREAM AND CONTAMINATING MATERIALS IN HIGHER CONCENTRATION THAN IN SAID FIRST VAPOR STREAM AND A LIQUID BOTTOMS CONTAINING WATER AND CONTAMINATING MATERIALS IN LOWER CONCENTRATION THAN IN SAID WASTE STREAM, PASSING SAID LIQUID BOTTOMS TO A BOILER, HEATING SAID BOTTOMS IN SAID BOILER TO PRODUCE A THIRD VAPOR STREAM HAVING THE SAME COMPOSITION AS SAID FIRST VAPOR STREAM, SPLITTING SAID THIRD VAPOR STREAM TO FORM SAID FIRST VAPOR STREAM AND A FOURTH VAPOR STREAM, UTILIZING SAID FOURTH VAPOR STREAM IN SAID PROCESS, PASSING SAID SECOND VAPOR STREAM TO A COMBUSTION ZONE WITH LIQUID FUEL TO PROVIDE HEAT FOR SAID HEATING STEP AND PRODUCE COMBUSTION GASES INCLUDING COMBUSTION PRODUCTS OF SAID CONTAMINATING MATERALS, AND VENTING SAID COMBUSTION GASES TO THE ATMOSPHERE.
