Abstract:
1. A process for cracking hydrocarbon feedstock containing vacuum resid comprising: (a) passing a vacuum resid containing hydrocarbon feedstock to a first thermal conversion zone, where the feedstock is heated to a temperature of less than 649° C., where at least 30 wt. % of the vacuum resid is converted to material boiling below 566° C.; (b) introducing said thermally converted resid to a vapor/liquid separator, said separator being in fluid communication with a steam cracking furnace, to form a vapor phase and liquid phase; (c) passing said vapor phase to said steam cracking furnace comprising a radiant furnace; and (d) recovering at least 30 wt. % olefins from the material exiting the radiant furnace of the steam cracking furnace (based upon the weight of the total hydrocarbon material exiting the radiant furnace).
