Processes and systems for the conversion of crude oil to petrochemicals and fuel products that incorporate steam cracking, fluid catalytic cracking, and conversion of naphtha to chemical-rich reformates

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 petroleum chemical products, including fuel products, involves the conversion of naphtha to mixed feed steam cracking, fluid catalytic cracking, and chemical-rich reforming . The feed to the mixed feed steam cracker may be a mixture of hard products from water addition room, a recycle stream from the C3 and C4 olefin recovery stages within the battery limits, and a recycle stream from pyrolysis gasoline and FCC naphtha aromatics extraction zone Includes Nate. The chemical reformate from the direct current naphtha stream is used as an additional feed to the aromatic extraction zone and / or mixed feed steam cracker.
