what is crude oil all about?

Question

i was been ask all about crude the origin

Answer 1

Crude oil is the unprocessed oil that is extracted from the earth without any refining. Once it is extracted, it must be refined into other products for use - such as gasoline, etc.

Answer 2

Crude oil is the stuff pumped from underground; it is raw crude. The only separation done to it is to siphon off the natural gases so only a liquid remains. That is the stuff that is tracked by the price of a barrel (55 gallons).

Then it is sent to a refinery to be cracked. The cracking tower takes the raw oil and heats it up slowly. Different products vaporize at different temperatures and are pulled off to other lines (which is why a refinery seems to be a mass of pipes they are all pumping different products.

The most valuable product produced is Sweet Crude.
From the Wikipedia: http://en.wikipedia.org/wiki/Sweet_crude
“Sweet crude oil is a type of petroleum. The word sweet refers to small amounts of hydrogen sulfide and carbon dioxide; sweet crude generally contains less than 0.5% sulfur. This high quality, low sulfur crude oil is commonly used for processing into gasoline and is in high demand, particularly in the United States and China.”

Crude Oil or raw Petroleum: http://en.wikipedia.org/wiki/Crude_Oil
Petroleum (from Greek petra – rock and elaion – oil or Latin oleum – oil ) or crude oil is a thick, dark brown or greenish liquid. Petroleum exists in the upper strata of some areas of the Earth's crust. It consists of a complex mixture of various hydrocarbons, largely of the alkane series, but may vary much in appearance and composition. Petroleum is used mostly, by volume, for producing fuel oil and gasoline (petrol), both important "primary energy" sources (IEA Key World Energy Statistics). Petroleum is also the raw material for many chemical products, including solvents, fertilizers, pesticides, and plastics. 88% of all petroleum extracted is processed as fuel; the other 12% is converted into other materials such as plastic. Since petroleum is a non-renewable resource, many people are worried about the consequences of its depletion. Due to its constant want in the world oil has occasionally been dubbed as the black gold.

Answer 3

well basically crude oil is the pure oil obtained from the ground. it contains different hydro carbons which are seperated through fractional distillation as they have different masses. for example when the crude oil, being the mixture of all these hydro carbons and all sticky, is heated to a certain level then these heavier hydro c's evaporate to a certain level and are caught forming petrol.
obviously this distillation starts at something like 20 degrees celcius continouly rising. crude oil cant really be used in its pure form for anything.

Answer 4

The term Crude oil refers to oil as it comes straight from the ground. Crude oil can be very thick and therefore has to be refined before use in vehicles.

Answer 5

Crude oil is the basis oil that comes from the ground, or under the sea, where they pull it up from Oil Wells. "Refined" oil is the process that takes place to make the oils for our cars and further processing give you gasoline. Crude is the pure unprocessed state!

Answer 6

Crude oil is simply the oil that is pumped or extracted out of the ground. There are many impurities in the oil that need to be removed and when they are thats how you get refined oil

Answer 7

I think you're asking where it really comes from. Like plants and stuff.

The story goes something like this...

1. These hydro-carbons have been captured from the atmosphere, and put into plants, -by photosynthesis, ie the sun.

2. These plants die, and make up the top layers of the soil, or sink to the bottom of a lake.

3. After so many years, thousands of feet of this stuff exists, and it retains the hydro-carbons. It gets covered up and compressed, it turns into oil. Nobody can really duplicated how long this really takes.

4. We find the oil, parse it into different 'burnables" butane, gasoline, diesel, road tar, etc.

5. We give back to nature what was originally taken from the atmosphere, ie the hydro-carbons. Some call it "pollution".

maybe God put the oil in the ground, for us to find it, and fulfill a destiny for human kind.

Answer 8

Crude oil is a delicious syrup that I put on my pancakes in the morning for breakfast.

Answer 9

it's the stuff you get from the ground before it's separated into components (gasoline, etc.)

Answer 10

It's really pissed off oil with dirty vocabulary!!!

(Seriously, it's unrefined oil...)
