VERFAHREN ZUM AUFARBEITEN VON ABFALLMATERIAL

摘要

Process for upgrading waste material containing hydrocarbons, especially waste material containing plastics. …When upgrading waste material by pyrolysis, gases are formed which contain hydrogen halide compounds, and these are neutralised by the addition of basic additive material. Since the fully reacted additive material increases the pyrolysis residue, it is desirable to monitor the feeding of the additive material. …Therefore, the pH is measured in the low-boiling pyrolysis oil which additionally also contains condensed steam, and the feeding of the additive material is automatically influenced as a function of the measurement. …This achieves extensive or at least sufficient binding of the pollutants with low use of additive material.
