Oil Spills Without Borders

Saturday, August 7th, 2010

Cleaning the sea of oil? Yep. The Gulf of Mexico? Nope. Try the Yellow Sea, China. Following a huge explosion at an oil terminal in north east China, hundreds of thousands of gallons of the black goo spilled into the sea. At first played down by the authorities, it now has a more memorable size.

China oil spill estimated to top Exxon Valdez

China’s worst known oil spill is dozens of times larger than the government has reported – bigger than the famous Exxon Valdez spill two decades ago – and some of the oil was dumped deliberately to avoid further disaster, an American expert said Friday.

China’s government has said 1,500 tons (461,790 gallons) of oil spilled after a pipeline exploded two weeks ago near the northeastern city of Dalian, sending 100-foot-high flames raging for hours near one of the country’s key strategic oil reserves. Such public estimates stopped within a few days of the spill.

But Rick Steiner, a former University of Alaska marine conservation specialist, estimated 60,000 tons (18.47 million gallons) to 90,000 tons (27.70 million gallons) of oil actually spilled into the Yellow Sea.

“It’s enormous. That’s at least as large as the official estimate of the Exxon Valdez disaster” in Alaska, he said. The size of the offshore area affected by the spill is likely to be more than 400 square miles, he added.

And a world away from China, on the Kalamazoo River, Michigan, some 1,000,000 gallons of flammable goo have poured into the river and are heading towards Lake Michigan.  “A nightmare in our own backyard.”

Update: Although Michigan’s spill represents only 32 percent of the amount of oil spilled per day in the ongoing BP oil disaster, the environmental implications of the leak are already clear. Not only has wildlife — including geese and muskrats — been coated in oil, but fears also remain high that the oil will contaminate local water supplies. The Calhoun County Health Department has advised residents around the area of the Kalamazoo River oil spill to evacuate, due to “‘higher than acceptable levels of benzene’ in air quality studies.” Benzene, notes the press release from the health department, is a “highly flammable” organic chemical that can lead to a series of symptoms from dizziness to tremors. The long-term effects of benzene exposure, however, are more dire and are linked to excessive bleeding and even cancer in human beings. Enbridge has agreed to reimburse affected families for the cost of hotel stays. [ThinkProgress]

Bobby Jindal’s “barrier islands” Are Washing Away

Friday, July 16th, 2010

From Climate Progress

Last month I warned that Gov. Bobby Jindal (R-LA) was demagoguing a sand barrier ’solution’ that probably won’t help, will take many months, use up valuable resources, vanish in the first storm — and many scientists think will make things worse. As one Coastal geologist explained: “I have yet to speak to a scientist who thinks the project will be effective.”

So I know you will be shocked, shocked that Jindal’s “obvious” response to the BP oil disaster is already failing. Brad Johnson has the story:

Since the beginning of May, Gov. Bobby Jindal (R-LA) has pushed a crash effort to build artificial “barrier islands” from dredged sand to prevent BP’s toxic oil from reaching Louisiana’s fragile coastline. He and other Louisiana politicians excoriated the federal government for waiting until June 3 to authorize the $360 million project, even though “categorically, across the board, every coastal scientistquestioned its wisdom. In mid-May, Jindal justified the barrier-island construction by saying it was the “obvious” thing to do:

It makes so much sense. It’s so obvious. We gotta do it.

We know it works, we have seen it work, but if they need to see it work, they need to do that quickly,” argued Jindal. On May 27, Sen. David Vitter (R-LA) attacked President Barack Obama, calling his administration’s caution “absolutely outrageous“:

Here the president doesn’t seem to have a clue. His decision on the emergency dredging barrier island plan is a thinly veiled ‘no.’ Approving two percent of the request and kicking the rest months down the road is outrageous, absolutely outrageous.

In fact, the first artificial island project is already showing serious signs of erosion, with heavy equipment sinking into the ocean. Photographs released by Louisiana scientist Leonard Bahr and the US Army Corps of Engineers show that the artificial island E-4, intended to reach an 18-mile length, is struggling to survive at 1,100 feet:

Nitrogen Runoff Creates Dead Zone: Add Oil – More Dead

Tuesday, July 6th, 2010

“While the BP oil spill has been labeled the worst environmental catastrophe in recent U.S. history, a biofuel is contributing to a Gulf of Mexico “dead zone” the size of New Jersey that scientists say could be every bit as harmful to the gulf.

Each year, nitrogen used to fertilize corn, about a third of which is made into ethanol, leaches from Midwest croplands into the Mississippi River and out into the gulf, where the fertilizer feeds giant algae blooms. As the algae dies, it settles to the ocean floor and decays, consuming oxygen and suffocating marine life.

Known as hypoxia, the oxygen depletion kills shrimp, crabs, worms and anything else that cannot escape. The dead zone has doubled since the 1980s and is expected this year to grow as large as 8,500 square miles and hug the Gulf Coast from Alabama to Texas.

As to which is worse, the oil spill or the hypoxia, “it’s a really tough call,” said Nathaniel Ostrom, a zoologist at Michigan State University. “There’s no real answer to that question.”

Some scientists fear the oil spill will worsen the dead zone, because when oil decomposes, it also consumes oxygen. New government estimates on Thursday indicated that the BP oil spill had gushed as much as 141 million gallons since an oil-rig explosion and well blowout on April 20 that killed 11 workers.

Corn is biggest culprit

Methane –> Ethylene –> Plastic –> Oil??

Saturday, July 3rd, 2010

As you will recall from recent reading, methane (CH4) is an enormously potent greenhouse gas, 21 times, by weight, more powerful than CO2.  We hear more about CO2 because it stays in the atmosphere doing it’s reflected-heat blocking for years more than methane does.  You will also know, as a matter of 21st century citizenship, that plastics — all around us– are a by-product of oil, the same oil spreading over the Gulf, and to which we are in thrall to.

It turns out that the plastics come from a long chain of “cracking,” chemically altering the basic crude oil into many products — among them, ethylene, which is used in the manufacture of plastic packing, anti-freeze, tires, footwear — thousands of classes of products!  So, if a way were found to make ethylene from methane two nice results would follow: methane would be used and in the process become not-methane and, less oil would be needed to produce the the same items, decreasing (we hope) one segment of our oil dependency.

This article doesn’t go into that “two-fer,” but does talk about the potentially important effects of their research — which, by the way, involved genetic engineering.

SAN FRANCISCO — A team of molecular biologists and materials scientists said Monday they had genetically engineered a virus to convert methane to ethylene more efficiently and at a significantly lower temperature than previously possible.

If they are successful in commercializing the new material, it will herald the arrival of a set of new technologies that represents a synthesis of molecular biology and industrial chemistry.

Ethylene, a gas with a characteristic sweet smell that may have once given insights to the Oracle of Delphi, is widely used in the manufacturing of plastics, solvents and fibers, and is essential for an array of consumer and industrial products. But it is still produced by steam cracking, a high-temperature, energy-intensive and expensive industrial process first developed in the 19th century. In this process, hydrocarbons found in crude oil are broken down into a range of simpler chemical compounds.

Ahab and the Gulf

Sunday, June 13th, 2010

Anyone who’s been around me these last weeks will testify to my mini obsession with what Moby Dick has to tell us about the Great Gulf Oil Vomiting of 2010. I’ve been listening daily to an audible telling of the great novel, all 136 chapters, available at Lit2Go from the University of South Florida (via iTunes.) In fact, the Pequod and all its crew but Ishmael, went to the bottom as I pulled into the garage this Friday. I sat of course, for a while, feeling the pressure of the watery grave. I’ve come to think that listening to the story, with all its erudite meanderings into amateur science, has been roping it into my dendrites much tighter than my former readings did. Perhaps it’s my age, or the year of this “reading.” But I get it now, more than I ever have.

They key point of comparison between the whale hunters and the oil hunters is that both, in their time, were the energy industry. Though wood and peat burning certainly provided warmth around the world, and coal had been mined since the time of the Romans there was nothing to compare to whale oil, especially sperm whale oil which didn’t smell as bad as right whale oil, for illumination, or for lubrication. As the whale population declined from voracious hunting, expeditions of 3 years and more as described in Moby Dick became the norm. Let’s call it far off-shore whaling. The essence of whaling was to pierce the animal with several sharp instruments — harpoons and lances– and bring the carcass alongside and extract the oil — from the blubber by refining it, and the precious spermacetti directly from the head. Call it sweet and heavy crude. The story of Moby Dick is, in a thimble full, the story of obsession, man’s drive to dominate, indeed revenge itself, against nature, and nature’s revenge against the world — the world of course being the Pequod with sailors and harpooners from every corner of earth.

It all seems impossibly predictive of what we see happening in the Gulf. Greed is more the driver than revenge, but domination of nature is still the mental set of those who have gone further and further off shore, to drive their deep drills into the earth to extract the precious stuff.

I’d been turning over a mid-sized essay to contemplate all this when lo and behold a pretty decent one appeared as the lead story in this Sunday’s NY Times, Week in Review. Randy Kennedy starts off:

“A quenchless thirst for whale oil, then petroleum, pushed man ever farther and deeper. And with great hubris, great risk.”

and continues:

A specially outfitted ship ventures into deep ocean waters in search of oil, increasingly difficult to find. Lines of authority aboard the ship become tangled. Ambition outstrips ability. The unpredictable forces of nature rear up, and death and destruction follow in their wake. “Some fell flat on their faces,” an eyewitness reported of the stricken crew. “Through the breach, they heard the waters pour.”

The words could well have been spoken by a survivor of the doomed oil rig Deepwater Horizon, which exploded in the Gulf of Mexico in April, killing 11 men and leading to the largest oil spill in United States history. But they come instead, of course, from that wordy, wayward Manhattanite we know as Ishmael, whose own doomed vessel, the whaler Pequod, sailed only through the pages of “Moby-Dick.”

“Now small fowls flew screaming over the yet yawning gulf; a sullen white surf beat against its steep sides; then all collapsed, and the great shroud of the sea rolled on as it rolled five thousand years ago.” — “Moby-Dick”

So I’m glad to recommend to you Kennedy’s piece. More judicious and less emotive than I might have been, nevertheless it’s worth remembering that man’s war against nature has been recognized for quite some while as a war that will not be won by the puny two legged creature, no matter how long his lances.

Fresh Squeeze Solar

Wednesday, June 9th, 2010

We usually have to plow deep for good news these days; here’s some just off the vine.

…[a solar power] invention that uses dye squeezed from berries. The dye acts as the chlorophyll in green leaves that allows the “Graetzel cell,” a layer of titanium dioxide nanoparticles, to absorb sunlight.

The invention is cheaper than the standard silicon photovoltaics in conventional solar power cells, making it a cheaper solution to the world’s energy problems, according to the Technology Academy of Finland.

The Graetzel cell can be used to power street lamps.

First Fatal Error on Gulf Rig

Wednesday, June 9th, 2010

I heard the other day an interview with Mike Miller, a long time oil-fire-blowup expert, and not just in academia. His crew from SafetyBoss took the lead in extinguishing the hundreds of oil fires in Kuwait set by the routed Iraqi army in 1991. He is very attuned to the enormity of the Gulf spill and the difficulty of working one mile under the sea. But, in an almost off-hand reply to a interviewer question he let loose a damning assessment of the actions on the rig in the first hours. I haven’t been able to locate the interview on line, but here is the gist of it in a Science News article.

… a number of people within the industry are themselves speculating widely about the accident as well.

Among them: Mike Miller, chief executive officer and senior well-control supervisor at Safety Boss. Headquartered in Calgary, Alberta, his half-century old Canadian company specializes in fighting oil-well fires, blowouts, pipeline ruptures and processing-facility fires. He’s curious why BP rushed to put out the rig’s fires.

“At least while the rig was burning, all of the effluent from the well was coming to the surface and burning at the surface,” Miller notes. Indeed, burning oil — even on the sea surface — is an accepted spill-mitigation technique. So he’s puzzled why water boats were deployed to dowse the burning platform.

A mile down and out of sight
“What they did was fill the rig up with water. At which point it sunk,” Miller says — a full 5,000 feet to the seabed. And that, he maintains, violated “the first rule in offshore fire-fighting, which is not to sink the ship.” The reason: As soon as the rig submerged, it took down the riser pipe, which in this case was a 5,000-foot-long tethered straw through which the oil was gushing up from a reservoir 13,000 feet below the seafloor.

This riser didn’t just break loose and fall down when the platform sank: It crumpled. And where it suffered acute bends, it weakened, opening up at least two secondary gushers. So instead of having the oil coming out as a single fountain at the Gulf’s surface — one that people could reach — it’s now spewing from multiple holes in a damaged pipe nearly a mile beneath the surface
