The "Barnett Shale" is a particular shale formation found in central North Texas, and Southern Ok, that can produce natural gas. The natural gas is the same gas found in any other formation only extracted a little differently. Propane would be refined from natural gas, with no regard as to where it came from. Crude oil, meaning oil extracted directly from the ground in it's natural state, is unrefined and can be full of impurities, water, etc., thus crude.
Difference between nymex crude and brent crude
The number of carbon atoms and therefore size of the molecules (Methane=CH4, Propane=C3H8) PROPANE IS A BY-PRODUCT OF CRUDE OIL REFINING. METHANE IS A GAS THAT WILL COME FROM ANYTHING THAT WILL NATURALLY DE-COMPOSE
crude fat is the fat with alcohol
Gasoline is a refined product derived from crude oil. Crude oil is a natural resource extracted from the ground, while gasoline is a processed fuel used in vehicles. The main difference is that crude oil is the raw material, while gasoline is the end product after refining crude oil.
fuel gases, because they have the smallest amount of carbons present...between 1 and 4.
a crude guess is just a mere guess while the intelligent guess is likely to happen due to your experience
Death Rate is the actual rate of death where Crude Death Rate is a guess on the death rate.
A very crude way of looking at the two is :EBIDTA (-) Interest (-) Tax = FFO.
Crude birth rate is how many live children are born. Crude death rate is how many people die. Crude death minus crude birth is the net gain (or loss) and is called the birth rate. It represents whether or not deceased people are "replaced".
Crude oil is a mixture of lots of different organic chemicals, there is alkanes (methane, ethane, propane ... octane ... C18H38) and alkalies, alcohols and lots of different hydrocarbons.
Crude Oil is a liquid.
Oil is a general term that refers to any liquid that is not soluble in water. Crude oil, on the other hand, specifically refers to the unrefined petroleum that is extracted from the ground.
