Abstract
The present invention relates to method of producing aromatics and light olefins from a hydrocarbon feedstock comprising the steps of: (a) subjecting the hydrocarbon feedstock to a solvent extraction process in a solvent extraction unit; (b) separating from the solvent extracted hydrocarbon feedstock obtained in step (a) a raffinate fraction comprising paraffins and a fraction comprising aromatics and naphtenes; (c) converting said fraction comprising aromatics and naphtenes in a hydrocracking unit and separating into a high content aromatics fraction and a stream high in light paraffins; (d) converting said raffinate fraction in a steam cracking unit into light olefins.
