Processes and systems for conversion of crude oil to petrochemicals and fuel products that incorporate steam cracking and fluid catalytic cracking

摘要

A process planning scheme is disclosed that enables the conversion of crude oil feeds into petrochemicals in an integrated manner with several processing units. This design utilizes minimum capital expenditure to produce a suitable feedstock for the steam cracker complex. An integrated process for converting crude oil to olefin and aromatic, and petrochemical products, including fuel products, includes mixed feed steam cracking and fluid catalytic cracking. The feed to the mixed feed steam cracker is fed from the pyrolysis gasoline and the FCC naphtha aromatics extraction zone within the battery limit and from the recycle stream from the naphtha, C3 and C4 olefin recovery stages from the water addition co- Of raffinate.
