Abstract
A process for the conversion of a petroleum feed to light olefins may comprise pretreating the petroleum feed to form one or more pretreated petroleum feeds and fractionating the one or more pretreated petroleum feeds to form a methane stream, an ethane stream, a C3-C4 stream, a light liquid fraction, and a heavy liquid fraction. The process may further comprise methane cracking the methane stream to form hydrogen, steam cracking the ethane stream to form a steam cracking product; dehydrogenating the C3-C4 stream to form a dehydrogenated stream; and steam enhanced catalytic cracking (SECC) the light liquid fraction and the heavy liquid fraction to form an SECC product.
