PROCESS AND APPARATUS FOR THE CONTINUOUS THERMAL CRACKING OF HYDROCARBON OILS AND HYDROCARBON MIXTURES THUS PREPARED

摘要

Process and apparatus for the continuous thermal cracking of hydrocarbon oils, which process comprises heating a hydrocarbon oil feed, introducing the hot feed into a soaking vessel (4, 40), having its interior divided into a plurality of consecutive, interconnected compartments (5, 44) and causing hot liquid to pass through the consecutive compartments prior to withdrawal of liquid material from the soaking vessel, and wherein gas present in each compartment is collected and withdrawn separately (7, 47) from the vessel.
