Abstract (en)
[origin: US2009301935A1] A process and apparatus for cracking liquid hydrocarbon feedstocks utilizes a vapor-liquid separator to treat heated vapor-liquid mixtures to provide an overhead of reduced residue content. Hot liquid bottoms from the separator are heat exchanged with cool hydrocarbon feedstocks for cracking to provide cooled liquid bottoms and preheated feedstock. At least a portion of the preheated feedstock is directed to a convection section of a pyrolysis furnace for additional heating and subsequent cracking.
