Abstract
The temperature of a crude oil provided from a crude oil preheat furnace to a crude tower is substantially minimized by controlling such temperature so as to maintain a desired minimum overflash flow in the crude tower. Also, the temperature of each of the individual coils in the preheat furnace are balanced with respect to each other. Such minimization and balancing results in substantially optimal utilization of the fuel provided to the preheat furnace which results in considerable economic savings with respect to the operation of the preheat furnace.
