  • Method for recovering low-temperature heat and application of the method to an aromatics complex
    Patent number: 9908061
    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.
    Type: Grant
    Filed: October 17, 2013
    Date of Patent: March 6, 2018
    Assignee: AXENS
    Inventors: Alain Dunet, Isabelle Prevost, Thierry Leflour
