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

摘要

Calcination agent for sewage sludge in a circuit (8) for the material separation of valuable materials from residues, whereby o 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, formed at the boiling point of hydrocarbons, o in the circuit (8) a heating stage (13) for distillates and o downstream a cooler (14) for residues after the circuit (8) are provided.
