Abstract: A CONTINUOUS PROCESS FOR THE LIQUID PHASE, NON-CATALYTIC, AIR OXIDATION OF SOUR WATER IN WHICH THE SULFUR COMPOUNDS IN THE WATER ARE CONVERTED TO NON-POLLUTING, NONOXYGEN DEMANDING COMPOUNDS INVOLVES HEATING THE WATER AND OXIDIZING THE HEATED WATER WITH COUNTERCURRENT OR CO-CURRENT FLOW OF THE WATER AND OXIDIZING MEDIUM. THE PROCESS RAPIDLY CONVERTS OBJECTIONABLE SULFIDES AND INTERMEDIATE SULFUR COMPOUNDS SUCH AS THIOSULFATES, TETRATHIONATES, POLYTHIONATES, SULFITES AND POLYSULFIDES TO SULFATE.
