    Abstract: The invention relates to a method and system for recovering power from the gaseous stream produced by a paraxylene - air oxidation reaction. Specifically, the invention is based on heating the gaseous stream from the oxidation reaction to a temperature of at least 600°C, recovering energy through an expander, heating the expander vent stream and recovering heat from the vent stream. The recovered heat is used to maintain the oxidation process, purification process, start-up the process, or re¬ start the process after an interruption.
