摘要： A process for cracking a hydrocarbon feedstock containing asphaltenes, wherein the asphaltenes are removed from the feedstock before the hydrocarbons undergo steam cracking. The process includes: (a) heating an asphaltene-containing hydrocarbon feedstock upstream with respect to a plurality of pyro lysis furnaces comprising at least two pyro lysis furnaces to form a vapor phase that is essentially free of asphaltenes and a liquid phase containing asphaltenes; (b) separating the vapor phase from the liquid phase; (c) transferring at least a portion of the separated vapor phase in parallel flow to at least two of the plurality of pyrolysis furnaces; and (d) cracking at least a portion of the hydrocarbons contained in the separated vapor phase in the at least two of the pyrolysis furnaces to form a cracked product. Several pyrolysis furnaces, e.g., from three to ten pyrolysis furnaces, can be used in the practice of the present invention.

摘要： The invention relates to a method for processing asphaltene-containing feed to a pyrolysis furnace by raising the final boiling point of the feed/steam mixture to the pyrolysis furnace to ensure fouling occurs lower in the convection section where the mixture of air and steam can burn off fouling deposits during decoking operations. The final boiling point of the feed stream is increased by adding a heavy essentially asphaltene-free high boiling point hydrocarbon to the feed stream before the feed stream enters the convection section of the pyrolysis furnace, whereby said fouling occurs lower in the convection section.

摘要： A process for cracking a heavy hydrocarbon feedstock containing non-volatile components and/or coke precursors, wherein a stripping agent is added to the feedstock to form an enhanced hydrocarbon blend which is thereafter separated into a vapor phase and a liquid phase by flashing in a flash/separation vessel, separating and cracking the vapor phase, and recovering cracked product. The stripping agent increases vaporization of the volatile fraction of the heavy hydrocarbon increasing the maximum feedrate capacity of the furnace.
