Proper heat integration is essential for efficient operation of any processing facility. Significant research on heat exchanger network design has yielded much needed improvements. New developments combine debottlenecking and heat integration efforts to improve total energy efficiency. This case study examines how to improve an existing exchanger network and process performance through a heat integration approach. New approaches. A new debottlenecking approach that overcomes limitations of conventional sequential unit-by-unit debottlenecking approach has been discussed.1 This method is simultaneous in nature. It is based on posing the debottlenecking task as a process integration task, whi
