Process scheme configurations are disclosed that enable conversion of crude oil feeds with several processing units in an integrated manner into petrochemicals. The designs utilize minimum capital expenditures to prepare suitable feedstocks for the steam cracker complex. The integrated process for converting crude oil to petrochemical products including olefins and aromatics, and fuel products, includes mixed feed steam cracking and gas oil steam cracking. Feeds to the mixed feed steam cracker include light products and naphtha from hydroprocessing zones within the battery limits, recycle streams from the C3 and C4 olefins recovery steps, and raffinate from a pyrolysis gasoline aromatics extraction zone within the battery limits. Feeds to the gas oil steam cracker include gas oil range intermediates from the vacuum gas oil hydroprocessing zone. Furthermore, vacuum residue is processed in a delayed coker unit to produce coker naphtha, which is hydrotreated and passed as additional feed to aromatics extraction zone and/or the mixed feed steam cracker, and coker gas oil range intermediates as additional feed to the gas oil hydroprocessing zone.

Process for the production of olefins and of middle distillates from a paraffinic feedstock, in which: a) a paraffinic feedstock resulting from a Fischer-Tropsch unit is recovered, the said feedstock containing a light fraction and a heavy fraction; b) the light fraction is sent to a catalytic cracking unit; c) the effluent resulting from the catalytic cracking unit is separated in a fractionation unit in order to obtain a fraction of light hydrocarbons, an olefinic fraction and a residual liquid fraction; d) the heavy fraction is sent to a hydrocracking/hydroisomerization unit; e) the effluent resulting from the hydrocracking/hydroisomerization unit is separated in a fractionation unit in order to obtain a middle distillates fraction, a naphtha cut having a maximum boiling point of less than 180 C. and an unconverted heavy fraction; f) a part of the naphtha cut resulting from the fractionation unit is sent to the catalytic cracking unit.

Aromatics extraction and hydrocracking processes are integrated with a stream pyrolysis unit to optimize the performance of the hydrocracking units by processing the aromatic-rich and aromatic-lean fractions separately in order to better control the hydrocracking operating severity and/or catalyst reactor volume design requirements.
