Publication number: 20230365876Abstract: Processes and systems for forming olefins and aromatics from naphtha. The process includes introducing a naphtha feed stream to an adsorption unit, the adsorption unit comprising an adsorbent. N-paraffins are adsorbed from the naphtha feed stream to the adsorbent, and an iso-paraffin stream is removed from the adsorption unit. A desorbent stream is introduced into the adsorption unit, the desorbent stream comprising a desorbent, and the n-paraffins are removed from the adsorbent with the desorbent, thereby forming desorbed bottoms. The n-paraffins are collected from the desorbed bottoms, thereby forming an n-paraffin stream. The the n-paraffin stream is introduced to a steam cracking unit, and olefins and aromatics are formed from the n-paraffin stream in the steam cracking unit.Type: ApplicationFiled: May 16, 2022Publication date: November 16, 2023Applicant: Saudi Arabian Oil CompanyInventors: Lianhui Ding, Sameer A.
