How good are you at troubleshooting problems with distillation systems? This interactive online course is designed to familiarize participants with some of the problems that can occur during the operation of distillation systems. After completing this course, participants should be able to describe problems that can occur when the feed rate to a distillation column is incorrect, problems that can occur when the amount of reflux going back to the column is incorrect, and problems that can occur when the reboiler in a distillation system is operated improperly.
