  • Method of and apparatus for incinerating an aqueous solution containing nitro compounds
    Patent number: 3954381
    Abstract: A concentrated aqueous solution containing nitro compound is incinerated in a chamber to produce a hot dry vapor that is fed through a heat-exchange chamber through which the unconcentrated aqueous solution containing the nitro compounds is dripped so as to evaporate the greater portion of the water in this solution and produce the concentrate that is incinerated. The incineration is carried out at a temperature above 1000.degree.C and the hot vapors leave the heat exchange chamber in a dry state. Thereafter these hot vapors are scrubbed in a tower to remove any particulate material therefrom and are allowed to escape into the atmosphere as a nonpolluting gas.
