<p>A continuous process for wet oxidation of aqueous waste liquors using oxygen gas is made safer by injecting an inert gas (16, 17, 18, 19, 20) into the waste liquors at a rate such that oxygen in the gas phase is diluted by the sum of generated water vapor, produced carbon dioxide and injected inert gas to a concentration less than required for spontaneous combustion at every location in the wet oxidation system comprising a reactor (4), effluent line (6, 7, 7a), pressure control valve (8) and separator (9), having surfaces not continually exposed to a continuous liquid water phase.</p> |
