Abstract
A regeneration process for olefin cracking reactor is presented. The process utilizes the nitrogen waste stream from an air separation plant and the partially combusted effluent stream from the olefin cracking reactor is used to heat the nitrogen waste stream. The control of the heating of the nitrogen waste stream can be achieved through redirection of a portion of the heat from combustion to generate steam.
