The reboiler generally supplies most of the energy required to effect component separation. If too much heat is supplied, the tower will flood; conversely, if too little heat is available, separation performance decreases via poor reflux ratio (pinching), excessive weeping or poor tray action. Proper design of reboiling systems involves coordinating aspects both outside and inside the tower. This Design Practice focuses on both of these aspects to ensure proper operation of the overall reboiler system. Important literature discussing these topics is also cited.
