Continuous thermal cracking process

摘要

A process is described for the continuous thermal cracking of hydrocarbon oils, which process comprises heating a hydrocarbon oil feed, introducing the hot feed into a soaking vessel having its interior divided into a plurality of consecutive, interconnected compartments, and causing hot liquid to pass through the consecutive compartments prior to withdrawal of liquid material from the soaking vessel. The gas present in each compartment is collected and is separately withdrawn from the soaking vessel.
