Alkylation is a process used to produce highly branched isoparaffins from the reaction of lighter olefins and isobutane in the presence of sulfuric acid as a catalyst. This highly branched isoparaffins is called alkylate – a blending component that constitutes approximately 10% – 15% of the gasoline pool in the U.S. Besides the ability to increase octane and lower Reid vapor pressure (RVP) in the gasoline pool, alkylate also reduce vehicles exhaust emissions with zero olefins, zero aromatics and low sulfur.
Orlen Lietuva Contracts DuPont Clean Technologies for STRATCO® Alkylation Technolology
WILMINGTON, Del., DuPont Clean Technologies (DuPont) has been awarded the contract to supply ORLEN Lietuva (ORLEN) with licensing, engineering, and technical services for a STRATCO® alkylation unit and a MECS® spent acid regeneration (SAR) unit at the Mažeikiai refinery in Mažeikiai, Lithuania. The Mažeikiai refinery processes an average of 8 million tons of crude per year with capacity of up to 10 million tons of crude per year. In order to increase refinery complexity and flexibility of the Mažeikiai refinery, ORLEN commissioned DuPont for a STRATCO® alkylation unit with 240 kmta (6,000 bpsd) alkylate capacity. The alkylation unit will utilize LPG in the conversion to alkylate, and therefore upgrade refinery profitability. The 75 mtpd MECS® SAR unit, also under license from DuPont, will provide the refinery with a consistent supply of sulfuric acid, which is utilized as the catalyst for the alkylation unit, while ensuring compliance with the region’s stringent emission regulations.
