Why is tar sand more expensive than conventional oil?

Tar sands oil is more polluting to produce, transport and refine than conventional oil because it contains more carbon and more toxic substances, such as heavy metals and sulfur.

Besides, Why doesn’t Canada refine its own tar sand oil?

This is due to higher transportation costs, limited pipeline access to western Canadian domestic oil, and the inability of refineries to process WCSB heavy crude oil.

Keeping this in mind, What are the pros and cons of tar sands?

• Very large supply. Second largest oil field in the world.
• Economically recoverable at today’s oil prices.
• Will help keep oil prices relatively low.
• Enormous growth potential. …
• Big economic driver in Alberta. …
• Stable source country (a rarity for oil)
• GHG emissions could potentially be minimized through CCS.

Why is tar sand the world’s dirtiest oil?

Tar sands extraction emits up to three times more global warming pollution than does producing the same quantity of conventional crude. It also depletes and pollutes freshwater resources and creates giant ponds of toxic waste. Refining the sticky black substance produces piles of petroleum coke, a hazardous by-product.

What is a major problem of oil shale and tar sands?

Besides helping push us toward global warming catastrophe, oil shale and tar sands development destroys species habitat, wastes enormous volumes of water, pollutes air and water, and degrades and defiles vast swaths of land.

Does Canada refine tar sand oil?

Once extracted, the bitumen is refined. Some refining is done within the oil sands region or other Alberta refineries, but most is sent to refineries all over North America via pipeline, rail or marine transport.

Can Canadian refineries process bitumen?

Bitumen is the heavy unconventional oil found in the Alberta tar sands (also called oil sands). Only a specialized refinery can process bitumen and turn it into refined products such as fuels. Few refineries in Canada can do it. None of the refineries in eastern Canada can refine large quantities of bitumen.

Does Canada refine oil?

Canada is home to 18 refineries: 5 in Alberta, 5 in Ontario, 2 in British Columbia, 2 in Saskatchewan, 2 in Quebec, 1 in New Brunswick, and 1 in Newfoundland and Labrador. Together they have a total refining capacity of nearly 2 million barrels of oil a day.

What are the pros of tar sands?

What are the cons of tar sands?

Cons

• Enormous GHG emissions. …
• Relatively low net energy return compared to other sources.
• Large amounts of water required: roughly 3:1.
• Water pollution. …
• Destructive to major boreal forest.
• Widespread habitat destruction, both on land and water.
• Requires expensive and risky pipelines.

Why are the tar sands bad?

In fact, oil from tar sands is one of the most destructive, carbon-intensive and toxic fuels on the planet. Producing it releases three times as much greenhouse gas pollution as conventional crude oil does. … In fact, it has become one of the fastest-growing sources of greenhouse gas emissions in that country.

How bad is tar sand oil?

In fact, oil from tar sands is one of the most destructive, carbon-intensive and toxic fuels on the planet. Producing it releases three times as much greenhouse gas pollution as conventional crude oil does. … In fact, it has become one of the fastest-growing sources of greenhouse gas emissions in that country.

What is the problem with Alberta oil sands?

Large enough to be seen from space, tailings ponds in Alberta’s oil sands region are some of the biggest human-made structures on Earth. They contain a toxic slurry of heavy metals and hydrocarbons from the bitumen separation process.

Which is considered the dirtiest form of fossil fuels to burn?

Coal is the dirtiest of the fossil fuels and responsible for over 0.3C of the 1C increase in global average temperatures – making it the single largest source of global temperature rise. Oil releases a huge amount of carbon when burned – approximately a third of the world’s total carbon emissions.

What is the primary disadvantage of oil shale and tar sand?

What are the major advantages and disadvantages of using heavy oils produced from tar sand and shale oil as energy resources? … disadvantages: low energy net yield, released co2 and other air pollutants when produced and burned, severe land disruption and high water use.

What are tar sands and why are they a problem?

Burning tar sands oil creates more pollution than regular crude. Because of its sludgy composition, mining and refining tar sands oil demands an enormous amount of energy. Tar sands generate 17 percent more carbon emissions than conventional oil.

What are the disadvantages of using oil shale?

Surface mining of oil shale deposits causes the usual environmental impacts of open-pit mining. In addition, the combustion and thermal processing generate waste material, which must be disposed of, and harmful atmospheric emissions, including carbon dioxide, a major greenhouse gas.

Is tar sands oil refined in the US?

Over 70 percent of all tar sands crude refined in the U.S. was processed in the Midwest refining region known as PADD 2 (see Table 2). Over one-third of all the crude refined there was sourced from the tar sands.

Does Alberta refine its own oil?

The new Sturgeon Refinery at Redwater, Alberta, near Edmonton, will start refining up to 80,000 barrels per day (bpd) of diluted bitumen into diesel and other light petroleum products in 2020. … The Alberta Petroleum Marketing Commission will supply most of the bitumen feedstock.

Does the US use tar sand oil?

America imports some tar sands oil, but expanding U.S. dependence on this polluting fuel is not in our national interest. … Tar sands oil is highly corrosive, and pipelines that carry it have proven more prone to spills than those for conventional crude.

What is the biggest refinery in Canada?

The Irving Oil Refinery is a Canadian oil refinery located in Saint John, New Brunswick. It is currently the largest oil refinery in Canada, capable of producing more than 320,000 barrels (51,000 m³) of refined products per day.

Where do Ontario refineries get their oil?

Ontario receives all of its crude oil imports from the U.S. Most of the U.S. imports come from the states of Texas, North Dakota and Indiana.
