Beschreibung
Zusammenfassung:	The invention relates to a method for recovering available low-temperature heat in a process and to the use thereof for reducing the energy consumption of said process. The invention also relates to the application of the method to an aromatic complex wherein the low-temperature heat is recovered at the head of distillation columns in the form of low-pressure steam and reused for reboiling other distillation columns of which the operating pressure may have been lowered.
