An oil tanker taking on fuel, or "bunkering" Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel, and ...
For diesel engines it depends on the type of fuel, for distillate fuels the cetane numbers are used. Cetane numbers are tested using a special test engine and the existing engine was not made for residual fuels. For residual fuel oil two other empirical indexes are used: CCAI and Calculated Ignition Index (CII).
The crack spread X:Y:Z reflects the spread obtained by trading oil, gasoline and distillate according to this ratio. Widely used crack spreads have included 3:2:1, 5:3:2 and 2:1:1. [1] As the 3:2:1 crack spread is the most popular of these, widely quoted crack spread benchmarks are the "Gulf Coast 3:2:1" and the "Chicago 3:2:1". [citation needed]
On the other hand, the gel point of crude oil is dependent upon the composition of the crude oil as some crude oils contain more or less components that dissolve the paraffins. In some cases the gel point of a crude oil may be correlated from the pour point. [1] [2] The gel points of some common petroleum products are as follows:
The three most quoted oil products are North America's West Texas Intermediate crude (WTI), North Sea Brent Crude, and the UAE Dubai Crude, and their pricing is used as a barometer for the entire petroleum industry, although, in total, there are 46 key oil exporting countries. Brent Crude is typically priced at about $2 over the WTI Spot price ...
The percentage, by volume, of 2,2,4-trimethylpentane in that mixture is the octane number of the fuel. For example, gasoline with the same knocking characteristics as a mixture of 90% iso-octane and 10% heptane would have an octane rating of 90. [ 5 ]
#2 Heating oil price, 1986–2022 Kerosene inventory stock levels (United States), 1993–2022. Heating oil is known in the United States as No. 2 heating oil. In the U.S., it must conform to ASTM standard D396. Diesel and kerosene, while often confused as being similar or identical, must each conform to their respective ASTM standards. [3]
The Oklahoma Geological Survey in 2015 published a map that displays gas wells with greater than 20 MCFG per barrel of oil. [2] They go on to display oil wells with GOR of less than 5 MCFG/BBL and oil and gas wells between these limits. The EPA's 2016 Information Collection Request for Oil and Gas Facilities (EPA ICR No. 2548.01, OMB Control No ...
