ABSTRACT:
A method and apparatus are provided for distillation of hydrocarbon oil subject to coking threshold temperature limits. A hydrocarbon oil is heated to a first predetermined maximum temperature above which coking is likely to occur. The heated hydrocarbon oil is introduced into a first distillation zone, wherein the heated hydrocarbon oil is separated into a liquid portion and a vapor portion. The descending liquid portion is withdrawn from the bottom region of the first distillation zone, and the withdrawn liquid is reheated to a second predetermined maximum temperature, above which coking is likely to occur in the return heater line. Finally, the heated withdrawn liquid is returned to a second distillation zone, wherein a second separation occurs to achieve increased valuable products recovery. A divider arrangement maintains the first and second distillation zones physically separate from each other.
