Crude oil energy density
Crude oil is referred to as either light, medium, or heavy, based on its density. The American Petroleum Institute gravity, commonly shortened to API gravity, compares the density of crude to water. An API gravity higher than 10 means the oil is less dense than water and will float on it. Where: ϒ o is the specific gravity of the crude oil at 60 °F, dimensionless °API is the API gravity, degrees API; The API gravity scale acts as an inverse relationship to density (and specific gravity), that is, as density increases, the API gravity decreases. Crude oil’s density is measured using API (American Petroleum Institute) gravity. A higher API gravity indicates a lower density. A higher API gravity indicates a lower density. The higher the Hydrogen has one of the highest energy density values per mass. Its energy density is between 120 and 142 MJ/kg. This means that for every…>> hypertextbook.com . Why Oil Is So Hard To Replace 5) Energy Density- Oil is a butter fried steak wrapped in bacon. Solar, Wind, and most other alternative energy resources are lettuce. Extra-heavy crude oil: API gravity below 10 °API (higher than 1000 kg/m³) The API degrees indicate whether a crude oil floats on water or sinks. Light crude oils flow easily and contain more volatile components, while extra-heavy crude oils are highly viscous to nearly tar-like and show a higher density. Intermediate oils are between these heavy crude oil (density is greater than or equal to 900 kg/m 3 and less than 925 kg/m 3), medium crude oil (density is greater than or equal to 850 kg/m 3 and less than 900 kg/m 3 ), and light crude oil (density less than 850 kg/m 3 ).
7 May 2018 But crude oil comes in different flavours (sweet, or low-sulphur, and sour, These two measures of quality – sulphur content and density – are the most incurring sulphur in crude oil through energy-intensive processing.
A comparison of the energy densities of heating oil and natural gas will readily show why it must be piped in, rather than stored on site, as a 1,000 units of natural gas are required to obtain the same amount of energy as one unit of heating oil. Per gallon, diesel fuel contains about 12% more energy than gasoline, Yield structure of crude oils with increasing density of crude - Yields of different crude oil distillation cuts are plotted as function of whole crude specific gravity. Fractions based on European and North American markets, and the typical differences in crude oil fractionation in the two markets are also shown. In 2010, the World Energy Council defined extra heavy oil as crude oil having a gravity of less than 10° and a reservoir viscosity of no more than 10,000 centipoises. When reservoir viscosity measurements are not available, extra-heavy oil is considered by the WEC to have a lower limit of 4° °API. 1) Residual Fuel Oil - The liquid or semi-liquid, high-boiling fraction of residue from the distillation of crude oil. 1 Gallon (U.S.) = 3.785x10-3 m 3 = 3.785 dm 3 (liter) 1 ft 3 = 0.02832 m 3 ; 1 barrel (US, oil) = 1.33 barrel (US, liq) = 5.61458 cu foot = 42 gallons (US, liq) = 158.9873 liter; 1 lb m = 0.4536 kg; Btu - British Thermal Unit Crude oil is referred to as either light, medium, or heavy, based on its density.

The energy density of high oxygen content bio-oil is only half of that of conventional fuel. Organic The oxygen content of crude oil is usually less than 2 wt%.
5 Oct 2018 Petroleum, also called crude oil, is a fossil fuel. When petroleum products such as gasoline are burned for energy, they release toxic gases where it was drilled, its sulfur content, and its API gravity (a measure of density).

In the Density vs temperature figure (°C), you see that the dark grey line represent this crude oil. Then use the dark grey line in the Crude oil volume correction figure (Density@15°C/Density@observed T). At 250°C the correction factor is 1.188. The volume of your crude oil at 250°C is 1000m 3 *1.188 = 1188 m 3.
Crude oils that are light (higher degrees of API gravity, or lower density) and sweet (low sulfur content) are usually priced higher than heavy, sour crude oils. This is partly because gasoline and diesel fuel, which typically sell at a significant premium to residual fuel oil and other "bottom of the barrel" products, can usually be more easily and cheaply produced using light, sweet crude oil. The energy density of a fuel refers to the energy produced per unit volume, and equals the energy released from the fuel, divided by the volume of fuel consumed. As I mentioned above, fossil fuels such as natural gas, oil and coal have relatively high specific energy, In the Density vs temperature figure (°C), you see that the dark grey line represent this crude oil. Then use the dark grey line in the Crude oil volume correction figure (Density@15°C/Density@observed T). At 250°C the correction factor is 1.188. The volume of your crude oil at 250°C is 1000m 3 *1.188 = 1188 m 3.

5 Sep 2007 You will see how crude oil pumped from the ground is transformed into It has a higher energy density than gasoline, and thus consumes less During chemical reactions, energy is either released to the environment ( exothermic For example crude oil has an energy content of about 45.2 kJ/g while density, thermal capacity, vapour pressure, chemical formula, etc. Crude oil is not used directly as a fuel but as a feedstuff for the petrochemical factories to produce long distances, was available to fuel the highly energy-intensive refining The energy density of oil is 35 to. 45 gigajoules (10,000 kWh) per cubic meter*. When measured using the methods presented, solar energy has a density of 1.5
