Process and apparatus for recycling cracked hydrocarbons

Processes and apparatuses are disclosed for catalytically cracking hydrocarbons comprising hydrotreating a residual feed stream and a recycle cracked stream comprising an oil to provide a hydrotreated effluent stream. The hydrotreated effluent stream is separated to provide a FCC feed stream and a distillate stream. The FCC feed stream is fed to a first riser reactor to provide a first cracked stream. The distillate stream is fed to a second riser reactor to provide a second cracked stream. The first cracked stream and the second cracked stream are fed to a main fractionation column. The first cracked stream and the second cracked stream are fractionated in the main fractionation column. The recycle cracked stream is taken from the main fractionation column.
