CEPA: Report Uncovers Diluted Bitumen Not Corrosive…

A report published on February 25 by a division of the UK-based Penspen engineering firm reveals diluted bitumen is no more corrosive than conventional crude.

Brenda Kenny, President and CEO, of the Canadian Energy Pipeline Association (CEPA), is pleased with the results of the report, which finally dispels the myth that industry critics have been spreading regarding the transportation of diluted bitumen.

“We have always known, based on scientific facts and our pipelines operational histories, that diluted bitumen is no more corrosive than conventional crude,” Kenny said. “Now, this manufactured myth can stop and Canadians can be further assured that our pipelines are safe regardless of the type of product they carry.”

According to CEPA, the report examined 40 studies addressing the behavior of diluted bitumen and conventional crude.  In these studies, which spanned over 40 years, the research concluded that diluted bitumen is no more corrosive when compared to conventional crude oil.

“It is important to have scientific evidence in front of Canadians, so they can make their own informed decisions, and not rely on misinformation”, Kenny said.

The report also showed that tests were carried out using internationally recognized standards, which found that small differences in some components of the product did not increase the chances of corrosion developing in oil transmission pipelines.  In addition, monitoring and preventative maintenance programs used by transmission pipeline operators on conventional crude oil pipelines were equally as effective on pipelines containing diluted bitumen.

The Canadian Energy Pipeline Association represents Canada’s transmission pipeline companies who operate approximately 110,000 kilometres of pipelines in Canada. In 2011, these energy highways moved approximately 1.2 billion barrels of liquid petroleum products and 5.3 trillion cubic feet of natural gas. CEPA members transport 97 per cent of Canada’s daily natural gas and onshore crude oil from producing regions to markets throughout North America.

Corrosion Committee to Explore Effects of Crude to be Transported by Keystone XL

Committee will analyze whether diluted bitumen has an increased potential for release compared to other crude oils.

NACE International – The Corrosion Society along with three of its ‘Fellow’ membership will participate on a newly appointed National Academy of Sciences (NAS) committee formed to analyze whether diluted bitumen (dilbit) transported by transmission pipeline has an increased potential for release compared with pipeline transmission of other crude oils. The NACE Fellows are Dr. Brenda J. Little of the Naval Research Laboratory, Dr. Srdjan Nesic of Ohio University and Dr. Joe H. Payer of the University of Akron.

A chief concern about the transport of Canadian crude through the proposed Keystone XL pipeline is a claim that dilbit poses more release risks than other types of crude. In particular, the committee will examine whether there is evidence that dilbit has corrosive or erosive characteristics that elevate its potential for release from transmission pipelines when compared with other crude oils. Should the committee conclude there is no evidence of an increased potential for release, it will report this finding to the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) by spring 2013. Alternatively, if the committee finds evidence indicating an increased potential, it will examine the adequacy of PHMSA’s pipeline safety regulations in mitigating any increased risk and report back to PHMSA by the fall of 2013.

“With all of the controversy surrounding Keystone XL, it is very important that a well-qualified team analyzes the risks, if any, of diluted bitumen,” said NACE Executive Director Bob Chalker. “NAS has put together the right group for the job. NACE supports this effort and I will be interested, along with many others, in seeing the final results.”
