Calcination agent for sewage sludge in cycles for the material separation of valuable materials from residual materials.

摘要

Calcination agent for sewage sludge in a circuit (8) for the material separation of valuable materials from residues, whereby ○ a distillation stage is provided for the formation of distillate in the circuit (8), in which one separation stage agent is the residues and the other is the distillate, created at the boiling point of hydrocarbons, ○ a heating stage (13) for distillates in the circuit (8) and ○ a cooler (14) downstream for residues after the circuit (8).
