You know that Keystone XL pipeline that President Obama is likely to approve? You know that foreign and possibly faulty steel TransCanada used in the Keystone 1 pipeline and has already been stockpiling here on the Great Plains for Keystone XL? You know that "tar sands oil," the mix of oil and grit that Keystone 1 transports and someday Keystone XL will transport across our land and aquifers?
Check out this video from the Oil Sands Discovery Centre, brought to you by the oil industry and the rah-rah-tar-sands Alberta government, to see what tar sands, also called bitumen, do to steel:
After enjoying that long Canadian "o" in "process," go to around 1:40 in the video to hear the presenter discuss the damage the bitumen does to her spoon. "It wears away all the steel equipment that it comes in contact with."
Now the tar sands transported in TransCanada's pipes are thinned to remove some of that sand. But the piped product is still heavy, gritty stuff. And that gritty oil moves through the pipelines at much higher temperature and pressure (try 1600 psi) than the nice lady is applying in her beaker with that spoon.
It wears away all the steel equipment that it comes in contact with. Reread that, President Obama.
p.s.: Grist contends the President may not be as likely as Moody's thinks to approve the pipeline, since the four main arguments he could make for the pipeline are weaker now than they were when he put off Keystone XL last winter.
pp.s.: And don't forget: the whole point of Keystone XL is not to supply the United States with more oil; it's to clear the glut of oil in the central U.S. and export that Canadian oil to the global market where it can fetch better prices.
ppp.s: The conservative (relatively speaking) Canadian government is so in the tank with the oil industry that it is muzzling Environment Canada scientists to keep them from talking about their own research on the pollution caused by tar sands extraction.
