Northern Alberta, Canada is the location of a really giant, wealthy oil sand discipline. The Athabasca oil sands are named for the Athabasca River, where the oil sands are simply seen from the river banks. One third of the world’s oil sands are found right here in Alberta, Canada and in Venezuela. The Athabasca oil sands subject is exclusive in that the oil sands are situated very close to the floor and can be simply surface mined. This makes it much cheaper to mine, and makes Athabasca the leading provider of oil sands in the world.
Oil sands are a strong form of oil also referred to as tar sands. They’re made up of clay and sands that are lined in bitumen oil. Bitumen oil is so thick that it have to be heated with the intention to make it move. Therefore, oil sands are very thick and sticky. Oil sands contain some water. This makes them sticky in the summer season and as solid as rock within the winter, when the water is frozen.
Strip mining is the easiest and most common option to mine for oil sands. To strip mine, we merely must dig a giant pit. Then we are able to drive in large trucks and bulldozers to get the oil sands out of the ground. We get the oil sands on to the trucks after which combine them with water. U-tube heat exchanger This helps break up the clumps and turn the oil sands right into a extra liquid substance called slurry. Turning the oil sands into slurry makes it attainable to transport through pipelines to a plant. At the plant, the oil is separated from the sand and the oil is distributed to a refinery for processing. Right here, the oil might be became synthetic oil and other petroleum products.
When deeper sections of the oil sands fields are encountered, then strip mining is not really an possibility. We need to go deeper to get to the oil sands. You’ll be able to see where this might create a challenge, considering that the oil sands are very sticky and could be strong or close to strong. To fight this downside, we are able to pump water into the bottom. Mixing the oil sands with the water turns it into slurry underground. This makes it much simpler to extract by merely pumping it out. Another type of extraction is to pump oxygen into the reserve. The oxygen is ready on hearth, in a managed vogue, and the bitumen is melted down to a liquid state. Then, the oil sands may be pumped out.
In some circumstances, we identify areas where oil sands are current by the tar pits that they will kind on the surface. Tar pits are formed when the pitch and tar rise up to the surface and separate from the sand. These pitch tar pits are well known for almost perfectly preserving prehistoric animals that received trapped in them. The most well known tar pit is the La Brea tar pit in California. One other well-known tar pit is in Trinidad. This tar pit is the size of a lake and could also be up to 2 hundred and fifty feet deep. It’s believed to be situated straight over a fault line in the earth.
