- the chlorinolysis unit (21) is withdrawn from perchlorethylene and carbon tetrachloride via line (29) and organic compounds other than perchlorethylene and carbon tetrachloride via line (30) and at least a fraction of these are removed.
- the compounds can be recycled to the chlorinolysis unit via the line (31) and / or fed to the high temperature oxidation unit of chlorinated compounds (23) via the line (32).
- Chlorinolysis and high temperature oxidation units of chlorinated compounds can be fed with organic products from other manufacturing units than those mentioned.
- the dichloropropanol production unit can be fed with hydrogen chloride and / or hydrochloric acid from manufacturing processes other than those mentioned above.
- the benefits of this scheme include:
- Process water is, for example, water from pumps or ejectors used to maintain the vacuum in the facilities. It can also be water obtained after decantation of organic.
