RAS LAFFAN INDUSTRIAL CITY, Qatar — The rat’s nest of pipes and columns snaking across the desert harbors a secret process that will use cobalt to turn natural gas into a powerful, clean-burning diesel fuel.
By next year, rulers of this tiny desert sheikdom hope, these gas-to-liquids (GTL) reactors under construction will bring in billions of dollars while clearing big-city smog belched by trucks and buses.
Petroleum experts who have sniffed vials of gin-clear GTL diesel speak of it with reverence.
“It’s a beautiful product,” says Jim Jensen, a Massachusetts-based energy economist. “The kerosene smells like perfume.”
In all, $20 billion has been committed to build an unprecedented array of clean diesel plants in this Gulf shore industrial park.
Those chipping in include oil titans Royal Dutch/Shell Group, Chevron and Exxon Mobil, which is making a $7 billion bet on GTL, the largest investment in the corporate history of America’s largest company.
Smaller plants in Malaysia, South Africa and the United States have proved the technology works, but none is nearly as large as those planned here. In a few years, says Andy Brown, who heads Shell’s office in Qatar, the country will be “the GTL capital of the world.”
“This really is where GTL will come of age, where the industry will be born,” he said.
By 2011, the Qatar plants should be producing 300,000 barrels of liquid fuels and other products daily. The largest GTL plant now producing is Shell’s plant in Bintulu, Malaysia, churning out 14,700 barrels per day.
The investments amount to a big Togel Singapore gamble on a clean alternative to pollutant-rich crude oil, based on an obscure “synthetic fuel” process developed to make fuel from coal in 1920s Germany.
Like Qatar’s headlong rush to produce liquefied natural gas, the ruling sheiks here are pushing GTL as an idea whose time has come.
The clean-burning fuel, with almost none of the smelly sulfur soot belched by engines firing on conventional diesel, appears tailor-made for countries looking to reduce emissions in line with the Kyoto Protocol on global warming.
Workers take a lunch break at the construction site of the Oryx Gas-to-Liquids plant north of Doha, Qatar. The plant, which is the largest of its kind in the world and expected to begin operation in 2006, will convert natural gas into clean-burning diesel fuel.
Faisal al-Suwaidi, chief executive of Qatar Liquefied Gas, said he’s gotten interest from Japan, Canada, Korea, Europe and the United States, the world’s largest polluter.
Although Washington has refused to sign the Kyoto protocols, state and local caps on emissions are pushing refiners to clean up diesel.
Complying with Kyoto’s strictures “is agenda item No. 1 when we visit countries like Japan,” al-Suwaidi said. “This is the product for them. This is green diesel.”
As far as carbon emissions go, green diesel appears to offer only a modest dent, partly because natural gas contains less carbon than oil-based diesel to begin with. The big difference is in sulfur.
Sulfur emissions from diesel engines cause as many as 10,000 deaths a year among Americans with heart and lung ailments, said William Becker, who represents state and local air-pollution-control agencies in the United States.
“It’s a matter of life and death,” Becker said. “And the solution depends on removing the sulfur.”
Emissions can be cut further by adding better filters that remove up to 90 percent of remaining particulates, said Richard Kassel, a fuels expert at the Natural Resources Defense Council in New York. Sulfur-laden diesel gums up these finer filters, he said.
“Clean fuels open the door to the most advanced emission controls,” Kassel said.
Tests of GTL fuel are under way in several countries. Shell is already selling the fuel in Thailand, The Netherlands, Greece and Germany, charging slightly more than its oil-based diesel. In Europe, Shell calls the fuel V-Power Diesel.
Environmentalists like Kassel caution that GTL fuel is most attractive when high oil prices make it competitive. The fuel will probably see most of its smog-cutting in developing countries where emissions standards will require better filters.
“It’s going to be a very important blending stock but the idea that it’s going to compete with crude oil is overstating the case,” Jensen said. “It sort of cuts down on the use of crude but it’s not going to massively change things.”
The fuel will be sell for more than conventional diesel, and is hugely profitable with current oil prices above $50 a barrel. But Shell will still profit if oil drops to $20, Brown said.
Exxon Mobil aims to produce 155,000 barrels per day by 2011, said Wayne Harms, Exxon’s chief in Qatar.
“We have a lot of money invested here. We’re going to invest a lot more,” he said. Exxon counts investments in some 200 countries, and Qatar “will be one of our top countries by the end of the decade,” he said.
