STRATCO® Alkylation Process Technology

STRATCO® Alkylation: The World-Leading Sulfuric Acid Alkylation Technology

With over 100 commercially operating units worldwide, the STRATCO® alkylation technology helps refiners safely to produce alkylate with high octane, low RVP, low sulfur, no aromatics and zero olefins, blending into the gasoline pool to create cleaner-burning gasoline.

Originally developed in the late 1930s and then licensed to refiners on a global scale, STRATCO® alkylation technology is based on almost a century of experience. We license sulfuric acid alkylation technology to oil refiners and offer equipment fabrication and lifelong support for our customized products and services. Our technology experts can work with you to assess and determine the right solution for your refinery. We support you every step of the way, from proposal, technology evaluation, and design through equipment fabrication, startup, and training. Our support continues in lifelong reactor component replacements, repairs, process-critical equipment, improvement studies, and operator training programs.

STRATCO® Alkylation Technology Licensing

Licensed and designed by Elessent, STRATCO® alkylation technology continues to be the preferred refinery technology for grassroots, revamp and expansion projects throughout the world. From Sinopec Qilu and Hengli Petrochemical Company in China to the Dangote Refinery in Nigeria, refineries around the world count on STRATCO® alkylation technology to produce clean fuel reliably while at the same time improving overall gasoline pool quality.

With more than 80 years of alkylation research and process design, along with extensive experience in optimizing, troubleshooting and analytical testing at customer sites, STRATCO® alkylation technology licensing is supported by comprehensive products and services that deliver lifelong support as well as the latest technology in alkylation and refinery solutions.
