Abstract
An apparatus for the cracking of a heavy hydrocarbon feedstock comprising a pre-pyrolysis cracker for treating the feedstock at elevated temperatures and pressures; a primary separator for separating the effluent from the pre-pyrolysis cracker into a heavy fuel oil fraction and a treated heavy hydrocarbon fraction; a pyrolysis furnace having a convection section for preheating and two radiant sections for partially cracking the treated heavy hydrocarbon and cracking a light hydrocarbon feedstock, a DUOCRACKER for completely cracking the heavy fraction while quenching the light fraction and a quencher for quenching the composite stream from the DUOCRACKER.
