Hydroprocessing (SCANfining™)
SCANfining™ technology offers a cost-effective solution for meeting the low sulfur requirements of gasoline. The technology removes sulfur with minimum octane loss by utilizing a jointly developed ExxonMobil/Albemarle catalyst technology coupled with ExxonMobil’s hydroprocessing design. With over 40 licensed units in operation, ExxonMobil brings demonstrated industry experience in offering customizable solutions to meet today’s refining challenges.

This robust catalyst system was designed through years of experimentation, resulting in a highly selective catalyst for removal of sulfur from FCC full-range naphtha. The technology allows multiple benefits, such as minimum hydrogenation of olefins (thus preserving octane), and reduced hydrogen consumption – up to 30-50% less than conventional hydrofinishing.

Flexible solutions
ExxonMobil’s customized solutions enable investment staging to meet the site-specific sulfur requirements. Depending on the product sulfur requirements, one or two reactors can be offered. SCANfining can be retrofitted using existing equipment, and there are multiple configurations that can best adapt the process to site-specific conditions, resulting in optimized investment. Zeromer™ technology can also be used for the catalytic destruction of mercaptans. Operational feedback and further research and development improve this technology continuously.
