Heat and mass balance control of refinery main fractionators can be improved through simple process design changes. Metering flows of internal reflux streams improves unit operability and controllability. Modifying the process system design to measure small internal reflux flow is another inexpensive way to control main fractionators. Three case histories show how simple design changes in refinery main fractionators can solve advanced control problems, thus changing product yields and improving refinery economics. The three cases are a delayed coker, a crude unit, and a FCC unit.
