EPA began regulating diesel fuel sulfur levels in 1993. Beginning in 2006, EPA began to phase-in more stringent regulations to lower the amount of sulfur to 15 ppm. This fuel is known as ultra-low sulfur diesel (ULSD). EPA's diesel program standards require that: These standards reduce harmful emissions from highway vehicles and …
To address this issue, the UK has implemented regulations that limit the sulfur content in diesel fuel.The current standard for diesel fuel in the UK is a maximum sulfur content of 10 parts per million (ppm). This low sulfur content helps in reducing the emissions of sulfur dioxide and improves air quality.. By using low-sulfur diesel fuel, …
sulfur content in heating and residual fuel oils that were not in effect prior to the 2010 study. In addition, New York City adopted a local rule that phased out the use of No. 6 residual oil in buildings by 2016 and lowered the allowable sulfur content in No. 4 fuel oil (a blend of No. 2 and No. 6) used as a replacement for No. 6.
The evolution of diesel fuel quality is summarized in the table below. India has reduced its diesel sulfur content from 10,000 ppm in most of the country in 1999 to a maximum content of 350 ppm in 2012. During this same time period, India reduced diesel sulfur content from 2,500 ppm to 50 ppm in thirteen major metropolitan areas.
The U.S. Environmental Protection Agency (EPA) has issued new standards to improve air quality. To meet EPA standards, the petroleum industry is producing Ultra Low Sulfur Diesel (ULSD) fuel, a cleaner-burning diesel fuel containing a maximum 15 parts-per-million (ppm) sulfur. In combination with cleaner-burning diesel engines and vehicles, …

Sulfur is a natural component in crude oil that is present in gasoline and diesel unless removed. Sulfur in gasoline impairs the effectiveness of emission …
Moving towards cleaner, low-sulphur fuels. In 2009, an update made to the British Standard BS 2869 for gas oil ruled that all on-road vehicles must be powered by gasoline or diesel with a maximum sulphur content of 10ppm. In 2011, the same mandates were imposed on non-road vehicles. In 2017 the EPA followed suit and …
Sulfur content in crude oil and petroleum products is a major problem, as the high content of sulfur in fuel leads to harmful emissions and leads to serious environmental and health risks as a ...
Since 2006, most distillate fuel has had less than 15 parts per million (ppm) of sulfur, a drastic change from the early 1990s, when high-sulfur diesel had an average sulfur content of 3,000 ppm. This change has improved air quality by reducing sulfur emissions with only a minor effect on the average energy content of distillate fuel …
Under the new sulphur limit, ships will have to use fuel oil on board with a sulphur content of no more than 0.50% m/m, against the current limit of 3.50%, which has been in effect since 1 January 2012. The interpretation of "fuel oil used on board" includes use in main and auxiliary engines and boilers.
When exploring the importance of sulphur, density and TAN it's worth referring back to WTI, Brent, and OPEC, the three most widely recognised benchmark oils. As the name suggests, WTI is produced in the United States. It's generally considered sweet and light, with sulphur …
Before EPA began regulating sulfur in diesel, diesel fuel contained as much as 5,000 parts per million (ppm) of sulfur. EPA began regulating diesel fuel sulfur …
As the name suggests, WTI is produced in the United States. It's generally considered sweet and light, with sulphur content of 0.24% and API gravity of 39.6. Brent ; Brent oil is extracted from the North Sea and is also considered a high-quality light and sweet product. With a sulphur content of 0.37% it's slightly less sweet than WTI.
The sulfur content of aviation fuel has not been regulated, however, and hits highs of 3000ppm - though aviation fuel averages 600ppm in practice. Moreover, an EASA report recently noted that the sulfur content of aviation fuel has been rising thanks to an increasing dependence on high sulfur crude oils from the Middle East and Venezuela.
The proposed amendments to the California diesel fuel regulations would reduce diesel fuel maximum sulfur content from 500 ppmw to 15 ppmw, starting in mid-2006. This lower sulfur limit would align California's sulfur requirement with the U.S. EPA's existing on-road rule, and the proposed off-road rule. However, the ARB's …
Studies estimate that the high sulphur content of marine fuel – which is much higher than levels allowable on land – contributes to between 19,000 and 91,000 premature deaths each year in coastal …
Recently, high sulfur content in diesel fuel is one of the main problems that have an effect on combustion and emission characteristics. Iraq is one of many countries in the world that use diesel fuel with high sulfur content. Therefore, the partially premixed combustion ignition (PPCI) concept and different blend ratios of gasoline–diesel ...
After subjecting the mimic to the desulfurization treatment, the resulting fuel's sulfur content equals 2.3 ppm — a value lower than even the most stringent environmental regulations mandate.
Common jet fuel specifications are shown in Table 1. Jet fuel specifications require total sulfur content to be less than 0.30 wt%. In order to comply, refinery and independent laboratories rely on standard test methods such as ASTM D4294 and ISO 8754. These labs operate in fast-paced environments that require rapid, precise results and are ...
VLSFO is a type of fuel oil with a sulfur content of 0.5% or less by weight. The creation of VLSFO was primarily driven by the International Maritime Organization's (IMO) regulation, known as IMO 2020, which mandated a hefty reduction in the sulfur content of ship fuels from 3.5% to 0.5% starting January 1, 2020. This regulation aims to ...
EU sulphur emissions from ships are regulated by Directive (EU) 2016/802 'Sulphur Directive'. Since 1 January 2010 this has required ships of all flags berthed in EU ports to use fuels with a 0.1% sulphur content limit, the fuel changeovers to be commenced as soon as possible after berthing and back again as close to departure as …
February 24, 2017. Scientists led by a team at Caltech have developed a new method for potentially removing nearly all sulfur compounds from gas and diesel fuel. Sulfur compounds in fuels such as gasoline and diesel …
Ultra-low sulfur fuel oil (ULSFO) has a sulfur content of 0.1% or less. This type of fuel is a refined product of residual oils. It is primarily used in ECA or to mix with HFO to form VLSFO. Some issues that must be considered when using treated or blended VLSFO and ULSFO are the reduced lubricity, the increased pour point (wax formation), …
fuel sulfur content (FSC) on premature mortality from long-term exposure to aviation-sourced PM2:5 (particulate matter with a dry diameter of <2.5µm) and on the global radiation budget due to changes in aerosol and tropospheric ozone. We estimate that present-day non-CO2 aviation emissions
However, aromatic and sulfur content is part of the chemical composition of the fuel and can be directly measured by analytical capabilities; therefore, predictions of aromatic and sulfur content will not be included in the discussions below. ... Expanded framework for the prediction of alternative fuel content and alternative fuel blend ...
With a planned effective date of January 1, 2020, the International Maritime Organization's (IMO) new regulations (IMO 2020) limit the sulfur content in marine fuels that ocean-going vessels use to 0.5% by weight, a reduction from the previous limit of 3.5% established in 2012. The IMO adopted the plan for this policy change in 2008, and in ...
Before 2006, most diesel fuel sold in the United States contained high quantities of sulfur. Sulfur in diesel fuel produces air pollution emissions that are harmful to human health. In 2006, the U.S. Environmental Protection Agency issued requirements to reduce the sulfur content of diesel fuel sold for use in the United States.
Strong changes in the fuel sulfur content led to changes in volatile particle size rather than particle number 37,39. Volatile particle numbers were further reduced in contrail conditions due to ...
This study develops a system named Wuhan University of Technology Intelligent Tracer (WUT-iTracer) for identifying ships using high-fuel-sulfur-content (FSC) fuel oil in port waters. The system integrates a land-based sniffing monitoring module and a numerical simulation module.
