PROCESS FOR RUNNING A PYROLYSIS PLANT

摘要

In a pyrolysis plant having a preliminary cooling stage and a final cooling stage, in the event of an operational malfunction of the preliminary cooling stage as indicated by temperature measurement of the pyrolysis gas cooled therein, the pyrolysis gas is withdrawn upstream of the final cooling stage and previously stored, cold pyrolysis gas is drawn from a gas reservoir and fed to the pyrolysis reactor and to the final cooling stage so that these parts of the plant can remain in unaltered operation. As a result of this procedure, a shutdown of the entire plant is avoided in the event of malfunctions of the preliminary cooling stage.
