Diluted bitumen from the oilsands can pose a substantial risk when carried through pipelines, says the Natural Resources Defense Council in a
report released this week.
"Increasingly, pipelines transporting tar sands crude oil into the United States are carrying diluted bitumen or "DilBit"—a highly corrosive, acidic, and potentially unstable blend of thick raw bitumen and volatile natural gas liquid condensate—raising risks of spills and damage to communities along their paths," says the report.
The Natural Resources Defense Council claims that the company's that produce oilsands are using conventional pipeline technology, however the operating temperature and pressure to push the bitumen down the pipes must be higher which can lead to ruptures, corrosion and leaks.
