The combustion of petroleum fuel products releases air pollutants, including oxides of sulphur ("SOX") that endanger public health and harm the environment. Sulphur compounds cause corrosion of pumps, pipes and refining equipment and premature failure of internal combustion engines, power generation units and steam boilers. Catalytic converters are degraded by sulphur and increase NOx formation. SOX is a major precursor to acidic deposition ("acid rain"), which is associated with the acidation of soils, lakes and streams, accelerated corrosion of buildings and reduced visibility.
All over the world, governments are imposing tighter standards on fuel quality and vehicle emissions. At the same time, air quality targets are rising. International and US regulatory bodies such as EPA, CARB and SCAQMD are responsible for publishing and enforcing air quality standards and have passed legislation on sulphur content in petroleum products.
IMO (International Marine Organization), for example, has regulated that Sulphur content in marine fuel must meet 0.5% worldwide starting in 2020 from the current Sulphur requirement of 3.5% in NECA. 0.1% Sulphur requirement must be met in ECA (Environmental Control Areas).
Why this is important and relevant to IUT is because it means that we are ahead of the curve and are working towards adapting our technology as an alternative and more economically viable solution to boat scrubbers. These scrubbers will likely have to be installed on ships - or their fuel will have to be purchased from terminals that sell desulphurized marine fuel at a premium.
With recent amendments to the sulphur content standards in various petroleum products by many countries, IUT technology is a value-ad opportunity from both an environmental compliance and cost perspective. Now more than ever, processing companies need to be on the lookout for new ways to meet stringent regulatory demands while being able to extract greater value from each barrel. . Many countries have mandated regulations on the production and use of ultra low sulphur diesel and gasoline to less than 15ppm even 10ppm with the trend continuing to less than 5ppm.
Current Regulatory Picture
Canada/US gasoline: 10 ppm sulfur
Canada/US On-road diesel: 15 ppm sulfur
Canada/US Non-road diesel: 15 ppm sulfur
Europe/China on road gasoline /diesel: 10ppm sulphur
