Abstract
A method of neutralizing and detoxifying waste material containing both an acid and a toxic organic compound. The waste material is combined with sufficient oil and sufficient caustic to form a pumpable slurry having a pH of 7 or higher. The oil is then separated from the slurry leaving a dry, deoiled material, containing a salt and the toxic organic compound. This material is pyrolyzed at a temperature below the melting point of the salt and sufficiently high to vaporize the toxic organic compound. The resultant vapor is then incinerated to detoxify the vaporized organic compound.
