Crude oil is considered "heavy" if it has long hydrocarbon chains, or "light" if it has short hydrocarbon chains: an API gravity of 34 or higher is "light", between 31 and 33 is "medium", and 30 or below is "heavy". Crude is considered "sweet" if it is low in sulphur content (< 0.5%/weight), or "sour" if high (> 1.0%/weight). Generally, the ...
The clear cut definition of light and heavy crude varies because the classification is based more on practical grounds than theoretical. The New York Mercantile Exchange (NYMEX) defines light crude oil for domestic U.S. oil as having an API gravity between 37° API (840 kg/m 3) and 42° API (816 kg/m 3), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m 3 ...

2 per unit of energy than does coal or oil, but more than natural gas. It emits 81% of the CO 2 per kWh produced by oil, 70% of that of coal, and less than 50% of that emitted by coal-generated electricity distributed via the grid. [40] Being a mix of propane and butane, LPG emits less carbon per joule than butane but more carbon per joule than ...
Global annual crude oil production (including shale oil, oil sands, lease condensate and gas plant condensate but excluding liquid fuels from other sources such as natural gas liquids, biomass and derivatives of coal and natural gas) increased from 75.86 million barrels (12.1 million cubic metres) in 2008 to 83.16 million bbl (13.2 million m 3 ...

The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
