Abstract (en)
A method and apparatus are provided for high temperature distillation of heavy hydrocarbon oil. The oil is heated to a high temperature, close to a coking temperature, then flashed in a first distillation zone into liquid and vapor. The liquid is withdrawn, reheated, then returned to a second distillation zone and separated into vapor and liquid. This increases distillable products recovery. Preferably a divider separates liquid in the first and second distillation zones, beneath a common vapor space.
