Fuels of the Future

The global fuels market will see a dramatic shift over the next 10 years. Despite its steep reduction in demand in 2020 due to the onset of the COVID-19 pandemic, global liquid fuel consumption is expected to surpass pre-pandemic levels sometime in 2022. Stricter fuel specifications, a changing vehicle fleet, the growing role of alternative fuels and the potential for a tightening crude market will determine developments of the fuel market through to 2030 and beyond. Europe has been leading the way towards cleaner, lower-emission fuels. The proposed Euro 7 standards are set to feature even stricter rules on emission levels for all gasoline and diesel cars, vans, trucks and buses. Other industrialised regions of the world are likely to follow. The pandemic has also accelerated the trend to decarbonise, reduce emissions and incorporate renewable fuels.

Reducing Acid Consumption: Maximizing Sulfuric Acid Alkylation Unit Profitability

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 Ma┼żeikiai refinery in Ma┼żeikiai, Lithuania. The Ma┼żeikiai 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 Ma┼żeikiai 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 regionÔÇÖs stringent emission regulations.
