Sulfur is a naturally occurring component of crude oil and is found in both gasoline and diesel. When those fuels are burned, sulfur is emitted as sulfur dioxide (SO 2) or sulfate particulate matter. Any reduction in fuel sulfur immediately reduces these sulfur compounds and, as sulfur levels decline past a certain point, the benefits increase .
May 31, 2018· Phase 1, which was implemented in 1991, eliminated lead from gasoline and set regulations for deposit control additives and reid vapor pressure (RVP). Phase 2 CaRFG (CaRFG2) set specifications for sulfur, aromatics, oxygen, benzene, T50, T90, Olefins, and RVP and established a Predictive Model.
Sulfur-containing compounds are present in petroleum feed stocks and products. This class of compounds is odorous, often disruptive to equipment, and detrimental to downstream processing. Therefore, sulfur-containing compounds are monitored through the entire refinement process.
Information about EPA's gasoline regulations, including the Tier 3 Gasoline Sulfur program, the Mobile Source Air Toxics rule, Reformulated Gasoline (RFG) regulations, and volatility requirements.
Mar 29, 2013· WASHINGTON — The Environmental Protection Agency will propose a rule on Friday that will cut the amount of sulfur allowed in gasoline by two-thirds to …
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 control systems and contributes to air pollution. Reducing the sulfur content in gasoline enables advanced emission controls and reduces air .
as oxygenates in gasoline, may affect the apparent sulfur reading. Other matrix related interferences may arise from heavy metal additives, lead alkyls, and elements such as silicon, phosphorus, calcium, potassium, and the halides, especially if present at concentrations greater than one tenth of the measured concentration of sulfur, or more than a few
pool. In order to maximize octane in the gasoline pool, refiners typically rely on models to optimize gasoline blending, while taking into consideration both physical and performance characteristics such as RVP, sulfur, benzene, olefins, aromatics, and octane.
The sulfur content of transportation fuels has been declining for many years because of increasingly stringent regulations implemented by individual countries or groups of countries. In the United States, federal and state regulations limit the amount of sulfur present in motor gasoline…
GM says that corrosion of fuel sensors is caused by abnormal levels of sulfur in gasoline sporadically occurring in certain parts of Canada and U.S. I have personally seen Chevron Techron used to clean the contacts and not have success because the "corrosion" actually disintegrated the "fingers" on the wiper.
Jan 19, 2017· January 17, 2017. by EJ Ledet and Mike Leister. Effective January 1, 2017, the U.S. Environmental Protection Agency (EPA) began requiring all U.S. gasoline to meet an annual 10 ppm average sulfur requirement as part of their new Tier 3 vehicle and fuel regulations.
fications on the sulfur content of motor fuels. Because FCC gasoline contributes up to 90 % of the sulfur to the gasoline pool, this has highlighted the importance of reducing sulfur directly in the FCC unit. Grace Davison has been providing catalysts and additives that reduce FCC gaso-line sulfur by up to 45% to the refining industry for over .
----- EPA Staff Paper on Gasoline Sulfur Issues I. Introduction The U.S. Environmental Protection Agency (EPA) is considering setting limits on the sulfur content of gasoline at this time primarily because advanced automotive catalysts are more susceptible to poisoning by higher sulfur levels.'
These regulations set limits on the amount of sulphur in gasoline produced, imported or sold. There is a temporary sulphur compliance unit trading system in place from 2017 to 2020. Regulations are current to 2017-11-20 and last amended on 2015-07-16.
EPA has now proposed a regulation to reduce gasoline sulfur. Adoption of the proposal would result in environmental benefits. But changes should be made to ensure that the requirements eventually adopted are as fair and affordable as possible.
Reducing Sulfur in Gasoline. The U.S. petroleum industry agrees with the U.S. EPA that lower gasoline sulfur levels are needed to help ensure continued improvements in fuels and air quality. For more than a year, the industry has been meeting with the agency to discuss how to accomplish this while minimizing impacts on gasoline supplies and .
Required the supply of ultra-low sulfur gasoline As of January 1, 2017, refiners are required to supply gasoline with 97% less sulfur content than the gasoline made in 2004. Gasoline with lower sulfur content reduces emissions from old and new vehicles and is necessary for advanced vehicle emission control devices to work properly.

Hydrodesulfurization (HDS) is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The purpose of removing the sulfur, and creating products such as ultra-low-sulfur diesel, is to reduce the sulfur dioxide (SO
Tier III Sulfur in Gasoline Analysis Under the law, the U.S. EPA is responsible for reducing or eliminating pollution. One of the central issues has been improvements in the quality of fuel burned in various types of vehicles.
Meeting Tier 3 Gasoline Sulfur Regulations Almost one year after first proposing the stricter vehicle emissions standards known as Tier 3, the US Environmental Protection Agency (EPA) finalized the new regulations on March 3, 20141. Tier 3 requires the U.S. oil industry to reduce the average sulfur level in gasoline by more than 60 percent, to .
Gasoline sulphur in North America Gasoline sulphur reduction toward 10 ppm has been slow in North America. Figure 1 shows the US average ppm sulphur in gasoline which, by regulation, has been 30 ppm max since 2012. EPA gave the industry six years to achieve a 10 ppm sulphur average by 2020. The chart shows that sulphur has been creeping down by 2 ppm per year.
PRODUCTION OF NO-LEAD, LOW-SULFUR GASOLINE IN PRE- SENT FACILITIES The time to plan, finance and construct refining facilities to upgrade gasoline blending components re- quires two to three years from the date of a firm de- cision to proceed.
Selective gasoline desulfurization with minimal octane loss. The UOP SelectFining™ Process, a recent addition to UOP's portfolio, reduces the sulfur in FCC gasoline, providing refiners with a simple, flexible solution to meet both current and future gasoline sulfur specifications.
Mar 03, 2014· EPA slashes sulfur allowed in gasoline to cut smog. The Environmental Protection Agency announced rules Monday to slash sulfur in gasoline by two-thirds as a …
Mar 04, 2014· Reducing sulfur is expected to cost less than 1 cent per gallon of gasoline, and $72 per vehicle to modify current technology to accept the new fuel--about half of what the EPA had originally .
