Abstract:
1. An apparatus for cracking a hydrocarbon feedstock comprising resid, comprising: (a) a heating zone for heating said hydrocarbon feedstock to provide heated hydrocarbon feedstock; (b) a mixing zone for mixing a primary dilution steam stream with said heated hydrocarbon feedstock to provide a heated two-phase stratified open channel flow mixture stream; (c) a vapor/liquid separation zone for treating vapor/liquid mixtures of hydrocarbons and steam, said zone comprising: (d) a pyrolysis furnace comprising a convection section, and a radiant section for cracking the vapor phase from the overhead vapor outlet to produce an effluent comprising olefins; (e) a means for quenching the effluent; and (f) a recovery train for recovering cracked product from the quenched effluent.
