  • Patent number: 4279865
    Abstract: The organic compound oxidation plant comprises vessels for organic compounds and for liquid-phase oxidizer, and a mixer for mixing organic compounds. The plant further includes a furnace for heating organic compounds and a reactor for oxidizing organic compounds. The top portion of the reactor is made cylindrical and accommodates a spraying unit for the supply of organic compounds and a liquid-phase oxidizer dispersion unit. The bottom portion of the reactor is made conical and accommodates a spraying unit additionally mounted therein at an angle to the reactor horizontal axis. Said latter spraying unit has nozzles ensuring the supply of organic compounds to the conical surface of the reactor. The nozzles of the spraying unit are provided with screens serving to ensure directional movement of organic compounds to the spraying unit and with openings for the supply of organic compounds, above which openings guide deflectors are mounted.
