Publication number: 20250051249Abstract: A process for converting whole crudes and other heavy hydrocarbon streams to produce ethylene. The process includes feeding a hydroprocessed medium boiling fraction, a hydroprocessed residue fraction, or both, and a light boiling fraction to a steam cracker and recovering a light fraction. The light fraction is fed to a first separator and recovering a C1-C3 stream and a mixed C4 and C4+ stream, comprising isoolefins, olefins, and dienes and feeding the mixed C4 and C4+ stream to a second separator and recovering a mixed C4 stream comprising isoolefins, olefins, and a C4+ stream. A portion of the mixed C4 stream is dimerized in a dimerization unit to produce a dimerized product stream, hydrogenated in a total hydrogenation system, producing a hydrogenated dimer product stream, and cracking the hydrogenated dimer product stream in a thermal cracking reactor system, producing one or more of hydrogen, methane, ethylene, propylene, n-butenes, and isobutene.Type: ApplicationFiled: August 7, 2024Publication date: February 13, 2025Applicants: LUMMUS TECHNOLOGY LLC, Saudi Arabian Technology Company, Chevron Lummus Global LLCInventors: Kandasamy Sundaram, Essam Abdullah Al-Sayed, Ronald Venner, Kareemuddin Shaik, Ujjal Mukherjee, Mazin Tamimi, Peter Kuzma, Saud Al-Dulaijan, Pedro Santos, Ibrahim Abba, Theodorus L.M.
