Publication number: 20200291311Abstract: Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.Type: ApplicationFiled: March 16, 2020Publication date: September 17, 2020Applicants: LUMMUS TECHNOLOGY LLC, Saudi Aramco Technologies Company, Chevron Lummus Global LLCInventors: Essam Abdullah Al-Sayed, Ujjal Mukherjee, Kareemuddin Shaik, Pedro Santos, Theodorus Maesen, Mazin Tamimi, Julie Chabot, Ibrahim Abba, Kandasamy Sundaram, Sami Barnawi, Ronald Venner, Raghu Narayan, Meredith Lansdown
