In North America, gas stations offer two types of diesel fuel – according to ASTM D975 [5] these are named No. 1 and No. 2 fuel. No. 1 fuel (similar to kerosene) has a natural CFPP of -40 °C but it is more expensive than No. 2 fuel. Adding No. 1 fuel will lower the CFPP of No. 2 fuel – adding 10% will lower the CFPP temperature by about 5 ...
The D5773 test method determines the cloud point in a shorter period of time than manual method D2500. Less operator time is required to run the test using this automatic method. Additionally, no external chiller bath or refrigeration unit is needed. D5773 is capable of determining cloud point within a temperature range of -60 °C to +49 °C.
The test is important in relation to the use of additives that allow spreading the usage of winter diesel at temperatures below the cloud point. The tests according to EN 590 show that a CloudPoint of +1 °C can have a CFPP −10 °C. Current additives allow a CFPP of −20 °C to be based on diesel fuel with a CloudPoint of −7 °C.
The cloud point (or gel point) can be adjusted down to −40 °C (−40 °F) [10] during the manufacturing process, compared to petrodiesel's cloud point of −30 °C (−22 °F), [failed verification] which could improve the cloud point of diesel when blended. The cloud point is the temperature when the wax precipitates out of the fuel in the ...
The standard EN 590 puts diesel fuel into two groups destined for specific climatic environments. ... Cloud point -10 -16 -22 -28 -34 °C Density at 15 °C 800 - 845 ...
The gel point of petroleum products is the temperature at which the liquids gel so they no longer flow by gravity or can be pumped through fuel lines. This phenomenon happens when the petroleum product reaches a low enough temperature to precipitate interlinked paraffin wax crystals throughout the fluid .
This was evident from the 20% year-over-year growth in Palo Alto's remaining performance obligations (RPO) in the first quarter of fiscal 2025 (which ended on Oct. 31, 2024) to $12.6 billion ...
LS9 diesel is above the competition in many varying facets including cetane number, sulphur content, aromatic compound content, cloud point and oxidative stability. In 2010, LS9 UltraClean Diesel was awarded status as an officially registered fuel by the United States Environment Protection Agency (EPA).
