Abstract:
A method for recovering heat available at low temperature in a process and its use in order to reduce the energy consumption of the said process, and application of this method to an aromatics complex in which the low-temperature heat is recovered at the head of distillation columns in the form of low-pressure steam and is reused to reboil other distillation columns in which the operating pressure has possibly been lowered.
