  • Production Of Liquid Hydrocarbon Mixture For Refining Petroleum (AREA)

Abstract

PURPOSE: Petroleum heavy oil, after combined with an oil containing a certain fraction of aromatics, is heat treated under specific conditions to prevent coking troubles and produce useful products such as gas, oil and pitch efficiently.
CONSTITUTION: Petroleum heavy oil is preheated with the charge heater 3 and combined with an oil boiling at 300W500°C and containing more than 60% of aromatics. After mixed uniformly, they are heat treated in the reactor 7 at 350W500°C and higher than 3kg/cm2. A part of the reaction mixture is sent to a recycle heater 15 and recycled to the reactor 7 to feed the heat. The liquid reaction product is sent from the reactor 7 to the reduced-pressure distillation column 21 and separated into gas, light oil and heavy oil.
