Oil sand processing extraction
22 Sep 2009 This unconventional oil is currently extracted using surface mining or in situ The liquid tailings, a by product of the oil sands mining process, 13 Dec 2012 They can be extracted and processed to separate the bitumen, which is upgraded to synthetic crude oil and refined to make asphalt, gasoline, Both in-situ recovery and mining methods are used to extract the resource, with surface mining used for extracting deposits of extra heavy oil at shallow depths of 9 Jun 2012 The Athabasca sands hold the second largest deposit of oil in the world and could eventually produce up to 2-trillion barrels of crude. But the type
At an oil sands mine, the overburden is stripped away and large mining machines load the sand into trucks that haul it to a nearby processing plant. At the processing plant, the oil sand is crushed and then treated with hot water and chemicals to liberate the bitumen.
The oil sand is mixed with warm water -- called a slurry -- and transported by pipeline to an extraction facility. Here, the slurry is put through a separation process where sand sinks to the bottom and impure bitumen froth rises to the top. Oil sands slurry produced in the Slurry Preparation Plant (SPP) contains about 50-55% sand and less than 10% bitumen. The purpose of Extraction is to recover the bitumen portion, while rejecting the heavy solids. This is achieved through a simple water-based gravity separation process, Learn about the process Suncor uses to extract bitumen from the oil sands: both surface mining as well as steam-assisted gravity drainage (SAGD) while trying to minimize our impact on the environment. Oil sand is a mixture of bitumen, sand and water. Because it does not flow like conventional crude oil, it must be mined or heated underground before it can be processed. Our oil sands business recovers bitumen through surface mining and steam injection technologies and upgrades it into refinery-ready crude oil products. The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel, negative environmental effects arise as a result of the extraction, upgrading, and processing of bitumen from the oil sands. Extracting bitumen from tar sands—and refining it into products like gasoline—is significantly costlier and more difficult than extracting and refining liquid oil. Common extraction methods include surface mining—where the extraction site is excavated—and “in-situ” mining, where steam is used to liquefy bitumen deep underground. "Petroteq's oil sands extraction process has been designed utilizing good engineering practices and confirmed chemical and physical principles. Many innovative chemical and engineering aspects have been incorporated into the process to achieve over 98% of bitumen extraction from the oil sands, and a greater than 99.5% solvent recycling efficiency.
Although oil sands are sometimes compared to Canadian tar sands, there are some significant differences. The oil sands are on the surface, rather than underground, so they don't require mining and
Andrew Prince. The oil product extracted from Canada's tar sands isn't like conventional crude. Known as bitumen, it's sticky and so thick, it can't flow down a pipeline without extensive processing. There are two methods for getting bitumen out of the ground and turning it into usable products. Water Impacts: The extraction of bitumen from oil sands requires a large amount of water, and thus water use is a concern when looking at oil sands extraction. Water used in the oil sands can be recycled, but only small amounts of this water are returned to the natural cycle. Once the oil sands ore is crushed, hot water is added so the ore can be pumped to the extraction plant. At the extraction plan more hot water is added to this slurry of sand, clay, bitumen and water in a large separation vessel where settling time is provided to allow the slurry components to separate.
Oil sands processing plants and bitumen extraction facilities require separate approvals prior to construction or operation. In addition, approvals are required for

The extraction and processing of oil sands do result in higher greenhouse gas ( GHG) emissions on average compared to light, sweet (low-sulfur) crude oil. But so
26 Apr 2014 Particularly energy intensive to process, tar sands oil was found in one the health effects of bitumen extracted from Canada's oil sands might 24 Dec 2015 Canada's oil sands (also called tar sands) are one of the largest oil deposits on earth. from this form of extraction than from conventional sources of oil. systems, we influenced the mining process before it commencement. 9 May 2013 oil resources, almost everyone agrees that production from Alberta's oil sands takes more energy to extract and process than conventional oil
10 Dec 2012 View a slide show of the oil sands process. be all the energy required to extract the oil from the tar sands—the burning of the resulting fuels in Oil sands are called “unconventional” oil because the extraction process is more difficult than extracting from liquid (“ 16 Jan 2012 The Clark hot water extraction (CHWE) process has been applied in commercial bitumen extraction from the Athabasca oil sands for more than Oil sands processing plants and bitumen extraction facilities require separate approvals prior to construction or operation.
