Resumo

Hydrothermal oxidation (HTO) has shown promise for destructing most industrial wastes by converting their organics constituents into pollution-free carbon dioxide, and water at conditions that exceed the critical point of water (Tc=374°C, Pc=218 atm). The main advantage of operating above the critical temperature of water is that organic compound, oxygen, and water exist in a single homogeneous fluid phase at these conditions. This single phase environment ensures intimate contact of the reactants. The miscibility of organics and oxygen with supercritical water guarantees the absence of interphase mass transport limitations for HTO. This is the main reason HTO can result in 99.999% destruction efficiencies of most organics wastes from the chemical, petroleum, pharmaceutical, textile, paper and pulp industries.
