What are the side effects of ultra low sulfur diesel?
While hydrotreating does increase the fuel’s cetane level, most of the side effects of hydrotreating are less than desirable. Fuel economy of ultra low sulfur diesel is estimated to decrease by 1% and, according to the EPA, severe hydrotreating also increases fuel production costs by 5 to 7 cents per gallon.
What happens when sulfur is removed from diesel?
Removing sulfur contents from diesel fuel has been shown to greatly alter the lubricity and overall chemical composition of the fuel. Refineries use severe hydrotreating to remove sulfur. This is a process which also happens to decrease diesel’s natural lubricity, lower energy density (fuel economy), and increases overall production costs.
Which is the best fuel additive for low sulfur diesel?
Addressing Low Sulfur To combat problems with ULSD effectively, including decreased lubricity, energy density, and fuel economy, use of broad spectrum fuel additive is considered best practice. A fuel additive can restore many of the lost properties of diesel while continually reducing emissions.
Why was ultra low sulfur diesel ( ULSD ) created?
In a nutshell, Ultra Low Sulfur Diesel (ULSD) was created in response to a number of regulatory actions aimed at reducing diesel fuel emissions. In 1970, Congress passed the Clean Air Act as a means to reduce harmful emissions from automobiles.
Are there any problems with ultra low sulfur diesel?
Operators of old diesel engines may want to replace gaskets and seals as very old gaskets shrink and leak when running on low sulfur fuels. However, EPA and the Engine Manufacturers Association do not anticipate problems burning ultra-low sulfur diesel in old engines.
When was low sulfur diesel fuel phased in?
From 2006 to 2010, ULSD was phased in for onroad diesel. All highway diesel fuel supplied to the market be ULSD; and All highway diesel vehicles must use ULSD. From 2007 to 2014, low sulfur diesel fuel (specified at 500 ppm) and ULSD fuel was phased in for nonroad, locomotive, and marine (NRLM) diesel fuel.
Addressing Low Sulfur To combat problems with ULSD effectively, including decreased lubricity, energy density, and fuel economy, use of broad spectrum fuel additive is considered best practice. A fuel additive can restore many of the lost properties of diesel while continually reducing emissions.
What is the sulfur limit for diesel fuel?
The sulfur content of the fuel used in marine vessels operating in these ECAs may not exceed 0.10 weight percent (1000 ppm). Note that a global sulfur cap of 3.50 weight percent applies outside of ECA boundaries. This limit decreases to 0.50 weight percent in 2020. The table default is to show all table entries.
