A
Black Mound of Canadian Oil Waste Is Rising Over Detroit
17
May, 2013
WINDSOR,
Ontario — Assumption Park gives residents of this city lovely views
of the Ambassador Bridge and the Detroit skyline. Lately they’ve
been treated to another sight: a three-story pile of petroleum coke
covering an entire city block on the other side of the Detroit River.
Detroit’s
ever-growing black mountain is the unloved, unwanted and long
overlooked byproduct of Canada’s oil sands boom.
And
no one knows quite what to do about it, except Koch Carbon, which
owns it.
The
company is controlled by Charles and David Koch, wealthy
industrialists who back a number of conservative and libertarian
causes including activist groups that challenge the science behind
climate change. The company sells the high-sulfur, high-carbon waste,
usually overseas, where it is burned as fuel.
The
coke comes from a refinery alongside the river owned by Marathon
Petroleum, which has been there since 1930. But it began refining
exports from the Canadian oil sands — and producing the waste that
is sold to Koch — only in November.
“What
is really, really disturbing to me is how some companies treat the
city of Detroit as a dumping ground,” said Rashida Tlaib, the
Michigan state representative for that part of Detroit. “Nobody
knew this was going to happen.” Almost 56 percent of Canada’s oil
production is from the petroleum-soaked oil sands of northern
Alberta, more than 2,000 miles north.
An
initial refining process known as coking, which releases the oil from
the tarlike bitumen in the oil sands, also leaves the petroleum coke,
of which Canada has 79.8 million tons stockpiled. Some is dumped in
open-pit oil sands mines and tailing ponds in Alberta. Much is just
piled up there.
Detroit’s
pile will not be the only one. Canada’s efforts to sell more
products derived from oil sands to the United States, which include
transporting it through the proposed Keystone XL pipeline, have
pulled more coking south to American refineries, creating more waste
product here.
Marathon
Petroleum’s plant in Detroit processes 28,000 barrels a day of the
oil sands bitumen.
Residents
on both sides of the Detroit River are concerned that the coke
mountain is both an environmental threat and an eyesore.
“Here’s
a little bit of Alberta,” said Brian Masse, one of Windsor’s
Parliament members. “For those that thought they were immune from
the oil sands and the consequences of them, we’re now seeing up
front and center that we’re not.”
Mr.
Masse wants the International Joint Commission, the bilateral agency
that governs the Great Lakes, to investigate the pile. Michigan’s
state environmental regulatory agency has submitted a formal request
to Detroit Bulk Storage, the company holding the material for Koch
Carbon, to change its storage methods. Michigan politicians and
environmental groups have also joined cause with Windsor residents.
Paul Baltzer, a spokesman for Koch’s parent company, Koch Companies
Public Sector, did not respond to questions about its storage or the
ultimate destination of the petroleum coke.
Coke,
which is mainly carbon, is an essential ingredient in steelmaking as
well as producing the electrical anodes used to make aluminum.
While
there is high demand from both those industries, the small grains and
high sulfur content of this petroleum coke make it largely unusable
for those purposes, said Kerry Satterthwaite, a petroleum coke
analyst at Roskill Information Services, a commodities analysis
company based in London.
“It
is worse than a byproduct,” Ms. Satterthwaite said.“It’s a
waste byproduct that is costly and inconvenient to store, but
effectively costs nothing to produce.”
Murray
Gray, the scientific director for the Center for Oil Sands Innovation
at the University of Alberta, said that about two years ago, Alberta
backed away from plans to use the petroleum coke as a fuel source,
partly over concerns about greenhouse-gas emissions. Some of it is
burned there, however, to power coking plants.
The
Keystone XL pipeline will provide Gulf Coast refineries with a steady
supply of diluted bitumen from the oil sands. The plants on the
coast, like the coking refineries concentrated in California to deal
with that state’s heavy crude oil, are positioned to ship the waste
to China or Mexico, where it is burned as a fuel. California exports
about 128,000 barrels of petroleum coke a day, mainly to China.
Tony
McCallum, a spokesman for the Canadian Association of Petroleum
Producers, played down the impact of Keystone XL. “Most of the
Canadian oil earmarked for the U.S. Gulf Coast is to replace
declining heavy oil imports from Mexico and Venezuela that produces
the same amount of petcoke, so it doesn’t create a new issue,” he
wrote in an e-mail.
Much
of the new coking investment has gone into refineries in the Midwest
to allow them to take advantage of the oil sands. BP, the British
energy company, is building what it describes as the second-largest
coke refinery in Whiting, Ind. When completed, the unit will be able
to process about 102,000 barrels of bitumen or other heavy oils a
day.
And
what about the leftover coke? The Environmental Protection Agency
will no longer allow any new licenses permitting the burning of
petroleum coke in the United States. But D. Mark Routt, a staff
energy consultant at KBC Advanced Technologies in Houston, said that
overseas companies saw it as a cheap alternative to low-grade coal.
In China, it is used to generate electricity, adding to that
country’s air-quality problems. There is also strong demand from
India and Latin America for American petroleum coke, where it mainly
fuels cement-making kilns.
“I’m
not making a value statement, but it comes down to emission
controls,” Mr. Routt said. “Other people don’t seem to have a
problem, which is why it is going to Mexico, which is why it is going
to China.”
“One
man’s junk is another man’s treasure,” he said. One of the
world’s largest dealers of petroleum coke is the Oxbow Corporation,
which sells about 11 million tons of fuel-grade coke a year. It is
owned by William I. Koch, a brother of David and Charles.
Lorne
Stockman, who recently published a study on petroleum coke for the
environmental group Oil Change International, says, “It’s really
the dirtiest residue from the dirtiest oil on earth,” he said.
Rhonda
Anderson, an organizing representative of the Sierra Club in Detroit,
said that the mountain’s rise took her group by surprise, but it
had one benefit.
“Those
piles kind of hit us upside to the head,” she said. “But it also
triggered a kind of relationship between Canada and the United States
that’s allowed us to work together.”
