Abstract
A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked to produce light olefins. A pyrolysis gas stream is separated into a light pyrolysis gas stream and a heavy pyrolysis gas stream. A light pyrolysis gas stream is separated into a normal paraffins stream and a non-normal paraffins stream. A normal paraffins stream is thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.
