What are the uses of tar sand?
Tar sand can be processed to extract petroleum, just like the kind that you get from oil wells.
Is tar sand a renewable resource?
No, it is a fossil fuel. Tar sand contains tar which is a fossil hydrocarbon similar to crude oil and ultimately derived from the same source.
Can oil be extracted from tar sand?
Yes, however it takes 4 barrels of water to produce 1 barrel of oil from the tar sand. (Sand and bitumen mix) Note the additional info posted below. The product is know as dirty oil which means it's incredibly costly to produce and is much worse for the environment than a more pure oil. Oil from the tar sands are essentially the leftover oil we have not yet overexploited. The heavy usage of water is required in the steam extraction method, used for very deep deposits of bitumen oil, used in asphalt. However, open pit mining, the other extraction process as in the Athabaska Valley of Northern Alberta, Canada, requires virtually no water in the extraction process.
Why could tar sands and oil shale become important energy resources in the near future?
They could supply fuels that now come from petroleum
Are tar sands and oil shale a good long-term energy solution?
No, they are non renewable sources, more difficult to extract than oil or coal and themselves will eventually run out.
What type of resources does tar sands come from?
Tar sands or oil sands are consist of clay, sand, water, and bitumen. Its bitumen content is extracted and separated to purify it into oil.
What is oil shales and tar sands?
Tar are usually mixture of clayand sand combined with water and varying amounts of a blackthick tar called bitumen. Oil shale is a rock that contains a waxy mixture of hydrocarbons called kerogen.
Some examples of non conventional energy?
tidal waves wind power fossil fuels tar sand heavy oil oil shale bio-fuels
Will oil sand and oil shale save us?
No
What are the uses of tar sand?
Tar sand can be processed to extract petroleum, just like the kind that you get from oil wells.
What are some energy sources is nonrenewable?
coal, natural gas, oil, oil shale and tar sands, nuclear power
Where is oil shale trapped?
Shale is a sedimentary rock that is structured in thin layers, like pages in a book. The oil is trapped between these "pages". Since the oil can't flow between the layers it only can be extracted at the broken edges of the shale deposit or by breaking the shale ip into tiny bits and washing the oil off for collection.
Is tar sand a renewable resource?
No, it is a fossil fuel. Tar sand contains tar which is a fossil hydrocarbon similar to crude oil and ultimately derived from the same source.
Which energy resources migth replace dwindling petroleum supplies one day?
Oil shale and tar sands
How do you make oil out of shale?
You don't make oil from shale, you extract oil from shale. The shale acts like a sponge, sometimes the shale is so porous that the oil can be squeezed or sucked out, otherwise it can be extracted by crushing and heating the shale.
What is a mixture of clay and sand with bitumen could replace petroleum one day?
The mixture of clay, sand, and bitumen that you mention is normally known as tar sand, and there are large deposits of it in the Canadian province of Alberta, as well as a few other locations. The bitumen can be extracted from the mixture and can then be refined into petroleum products such as gasoline, etc. This is more expensive than using oil from oil wells, however, in a world of very high and ever increasing oil prices, the exploitation of tar sands has become economically viable.
Is tar a renewable resource?
No, it is a fossil fuel. Tar sand contains tar which is a fossil hydrocarbon similar to crude oil and ultimately derived from the same source.
