<p>A method for regulating, or controlling heat input to the reboiler section of a fractionation column. Flowmeasuring means, disposed in a substantially liquid-free environment within the confines of the reboiler section, produces a signal which is representative of the quantity of vapor flowing from the reboiler section upwardly into the fractionation section. this signal is transmitted to heat-varying means, whereby fuel input to an external reboiler heater is regulated in response to the quantity of vapor flow.</p> |
