2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX ALKYLATION Sulfuric Acid Alkylation technology Propane product Refrigeration Application: Axens offers proven light ends upgrading technology for alkylate production. Compressor Description: Upgrading light olefins and isobutene to alkylate offers refiners an opportunity to increase their crude barrel value. Alkylate is a superior gasoline blendstock due to its high octane and low-vapor pressure. ExxonMobil's proven Sulfuric Acid Alkylation technology reacts propylene, butylene and pentylene with iso-butane to form high-value alkylate for gasoline blending. Advantages: The advantages of this technology include: * ExxonMobil's experience in inventing, designing and operating the technology * High reliability in line with FCC cycles * Less major equipment * Up to 10,000 bpd reactor capacity produces economies of scale * Direct vaporization of C3 results in energy savings * Multiple mixing zones in the reactor increases reliability * More than 50 years of ExxonMobil and licensee operating experience from 2,000 bpd-100,000 bpd * Flexibility in partnering with multiple sulfuric acid (H2SO4 ) regeneration technologies Fractionator Olefins feed Reactor and settler ExxonMobil's robust reactor design Butane product Recycle iC4 iC4 feed Alkylate product Licensor: Axens (technology formerly licensed by ExxonMobil Catalysts & Licensing LLC) Website: www.axens.net Contact: www.axens.net/contact.html Copyright © 2020 Gulf Energy Information.
