1. A process for producing light olefins comprising:
thermally cracking a cracking feed stream to provide a cracked stream;
separating a pyrolysis gas stream from said cracked stream;
separating said pyrolysis gas stream into a light pyrolysis gas stream and a heavy pyrolysis gas stream;
separating said light pyrolysis gas stream into a normal paraffins stream and a non-normal paraffins stream; and
separating a pyrolysis aromatics stream from said light pyrolysis gas stream and said heavy pyrolysis gas stream and saturating said pyrolysis aromatics stream to provide a saturate stream.
