ABSTRACT:
The disposal of chlorinated pitches is carried out by a process which employs two treatments with an alcohol, which are carried out in cascade.
Such treatments cause the precipitation of the suspended matter to take place. This is then caused to settle, and is separated and pyrolized, while the supernatant is distilled in order to separate the alcohol, which is recycled back to the process, from other organic components, which are sent to further uses.
