High severity fluidized catalytic cracking systems and processes for producing olefins from petroleum feeds

A system for producing at least one petrochemical product from a hydrocarbon material, the system comprising:

• a first cracking reaction zone;
• a first separation zone downstream of the first cracking reaction zone;
• a first regeneration zone downstream of the first separation zone;
• a first stripping zone downstream of the first separation zone;
• a first riser positioned between the first stripping zone and the first regeneration zone;
• a second cracking reaction zone in parallel with the first cracking reaction zone;
• a second separation zone downstream of the second cracking reaction zone;
• a second regeneration zone downstream of the second separation zone, where the second regeneration zone is physically separated from the first regeneration zone;
• a second stripping zone downstream of the second separation zone;
• a second riser positioned between the second stripping zone and the second regeneration zone;
• and
• a flue gas flow path extending from the first regeneration zone to the second regeneration zone, the flue gas flow path comprising a particulate barrier for preventing a transfer of one or more spent catalysts between the first regeneration zone and the second regeneration zone.
