ABSTRACT:
A control method and system for regulating the heat input to the reboiler section of a distillation column having attendant thereto a first external heat-recovery reboiler. Flow-measuring means, disposed within a substantially liquid-free environment, produces a signal which is representative of the quantity of vapor flowing from the reboiler section upwardly into the fractionation section of the column. This signal is transmitted to heat-varying means whereby the heat input to a second external reboiler heater is regulated in response to the quantity of vapor flow.
