An integrated process for producing light olefins and aromatics from residual hydrocarbon streams comprising: a) subjecting a residual hydrocarbon stream to catalytic cracking to produce a catalytically cracked effluent, wherein the catalytically cracked effluent is fractionated into a C3-C4 stream, light cracked naphtha, heavy cracked naphtha, light cycle oil, and clarified oil, b) separating the C3-C4 stream into a propylene containing stream and a butylene and pentene containing stream, c) subjecting the butylene and pentene containing stream to metathesis and separation to produce propylene and hexenes, wherein hexenes is aromatized to produce benzene and alkyl substituted benzenes and an unconverted stream, d) selectively hydrogenating the light cracked naphtha to produce a selectively hydrogenated stream comprising olefins and saturates, e) subjecting the selectively hydrogenated stream to extractive distillation using a solvent to form an extract stream containing aromatics along with sulfur compounds and a raffinate stream containing olefins and hydrotreating the extract stream to obtain stream, f) combining heavy cracked naphtha along with liquid hydrocarbon streams boiling in the range of C5-210°C from a delayed coker unit in a circulating fluidized bed reactor for fractionation into dry gas, C3-C4 stream, liquid hydrocarbon streams boiling in the range of C5-70°C, 70-170°C and 170°C+, g) hydrotreating the light cycle oil to produce an intermediate stream, h) hydrocracking the intermediate stream to produce a hydrocracked stream which is fractionated into additional products, i) hydrotreating the clarified oil to produce a hydrotreated stream, wherein hydrotreated stream is fed to a delayed coker unit to produce lighter products and needle coke, wherein the lighter products are gases, the liquid hydrocarbon streams boiling in the range of C5-210°C, and diesel, wherein the process yields light olefins in a range of 11 - 15 weight% and aromatics in a range of 15-21 weight% wherein in the weight % is with reference to the residual hydrocarbon stream. a) subjecting a residual hydrocarbon stream to catalytic cracking to produce a catalytically cracked effluent, wherein the catalytically cracked effluent is fractionated into a C3-C4 stream, light cracked naphtha, heavy cracked naphtha, light cycle oil, and clarified oil, b) separating the C3-C4 stream into a propylene containing stream and a butylene and pentene containing stream, c) subjecting the butylene and pentene containing stream to metathesis and separation to produce propylene and hexenes, wherein hexenes is aromatized to produce benzene and alkyl substituted benzenes and an unconverted stream, d) selectively hydrogenating the light cracked naphtha to produce a selectively hydrogenated stream comprising olefins and saturates, e) subjecting the selectively hydrogenated stream to extractive distillation using a solvent to form an extract stream containing aromatics along with sulfur compounds and a raffinate stream containing olefins and hydrotreating the extract stream to obtain stream, f) combining heavy cracked naphtha along with liquid hydrocarbon streams boiling in the range of C5-210°C from a delayed coker unit in a circulating fluidized bed reactor for fractionation into dry gas, C3-C4 stream, liquid hydrocarbon streams boiling in the range of C5-70°C, 70-170°C and 170°C+, g) hydrotreating the light cycle oil to produce an intermediate stream, h) hydrocracking the intermediate stream to produce a hydrocracked stream which is fractionated into additional products, i) hydrotreating the clarified oil to produce a hydrotreated stream, wherein hydrotreated stream is fed to a delayed coker unit to produce lighter products and needle coke, wherein the lighter products are gases, the liquid hydrocarbon streams boiling in the range of C5-210°C, and diesel, wherein the process yields light olefins in a range of 11 - 15 weight% and aromatics in a range of 15-21 weight% wherein in the weight % is with reference to the residual hydrocarbon stream. wherein the process yields light olefins in a range of 11 - 15 weight% and aromatics in a range of 15-21 weight% wherein in the weight % is with reference to the residual hydrocarbon stream.
