Earth at Night: The Natural Gas Burn-off

Postby MonteQuest » Sun 12 Dec 2004, 20:02:40

In the November issue of National Geographic, there is a fold-out map of the earth at night taken from space.
http://peakoil.com/fortopic2981.html
This photo shows the population centers and the bright glow of electric lights. But the map in the magazine also shows the forest fires, night fishing, and one other very telling detail--the flaring off of natural gas around the world. The highest concentrations are in Nigeria, Iran and Russia. Nigeria alone accounts for 20 % of the world's flares. Northern Russia is ablaze as well as the North Sea. This map is a must see! More than 100 billion cubic meters are burned off annually, enough to power France and Germany for a year. Oil companies searching for oil regularly burn off the gas and consider it worthless unless it can be transported. It appears that 80 percent of the world's reserves lack pipelines to transport it to consumers. Sounds like a lot of pipeline building to me. Is this "big oil's " back up plan?

Natural Gas Burned As Worthless Gets New Life

$this->bbcode_second_pass_quote('', 'L')ast month Exxon Mobil inked an agreement with Qatar Petroleum, the state-run oil company of the OPEC-member country. The deal calls for Exxon Mobil to construct a plant that will produce 6.5 million gallons of fuel a day when it comes on line in 2011. Cost: $7 billion.
Harry Longwell, Exxon Mobil's executive vice president and director, says the company's official stance is that crude oil will continue to reign well into the middle of this century and probably beyond, but conversion of natural gas into liquids can give them flexibility.
The company's commitment in Qatar shows gas-to-liquids is no mere pipe dream. Exxon Mobil has spent 20 years and $600 million on front-end investments in this technology. It holds a staggering 3,500 U.S. and international patents related to this work.
"It's important to look at the total energy growth requirement," Longwell says. "We look to 2020 and think we'll need 20 percent more energy than we do now. We're interested in products that have interchangability."
Royal Dutch-Shell, ConocoPhillips, ChevronTexaco, Marathon and South Africa's Sasol are all in various stages of development for gas-to-liquids plants in the Middle East.
The focus for projects to prove this technology is Qatar. It's a natural starting point because the producer of oil sits atop the world's largest natural gas field, and many of the biggest oil companies have operations in the Persian Gulf state.

After oil has declined. If the gas to liquid projects work. With gas to liquid still being a finite fuel source.

Do you think man kind will learn from the oil age and look past the gas to liquid age with a plan?

I have a feeling that it will occur much like the transition from being an exporter of oil to an importer for the USA in the early 70's. For most people, they won't even know or care. Remember my thread on energy illiteracy? It will be an add-on much like nuclear power. The fix will be on. Life goes on. Death to the doomsayers. Maybe it will be different, but I doubt it. However it pans out, it will be a struggle though.

We all know that natural gas is next in line for the dominant energy source post-peak oil. Here is a great article with some worthy insights into the field.


A Conundrum - The Natural Gas Market
$this->bbcode_second_pass_quote('', 'T')he natural gas market can easily be considered an enigma wrapped in a riddle. US storage is at record levels yet prices are historically high. Drilling is at record levels yet supplies are falling. There exists an almost unexplainably large gap between natural gas spot prices and futures prices. While the recent surge in crude prices can be credited for some of the recent gains in natural gas prices, I believe there are several unrecognized trends that are shaping the North American natural gas market. Probably the most important reason to expect to see North American natural gas prices continue to escalate is that production continues to decline. US natural gas production continues to fall despite record drilling activity.

HA EAT THAT ECONOMISTS. Apparently there's a finite amount of natural gas and it is not a function of money! WHODATHUNK!

Look how clueless they are. They simply don't understand the earth is finite. All the drills in the world won't save you if there is no natural gas in the ground.

That still does not change the fact that Natural Gas is going into decline in the USA. Oil is about to Peak, period, we run our economy on oil and not natural gas.

monte quest,

there are burning oil soaked mountains in Azerbajan, Iran etc. but they are not commercial finds.

Isolated pockets of Natural gas do exist...and probly a lot more than most think...

The question is does it pay for the eqpt./pipelines to come in and tap it?

Let's say the fields in Nigeria and russia do pay off...

Who will get it, China?

These reserves are known to National Geographic....I would fathom that Cambell / Jean count them as well. In fact we do have 20 years more...but is that true if we replace the Oil w/ Gas?

besides trucks and cars on natrual gas would need some safety overhauls before I would support them. Small household methane tanks are a favorite for terrorists to use as an explosive...so think about what dammage an Accident on a hyway would cause....

I'd suppose it looks like Canada is about to hit Peak Gas, huh. The author called it the natural gas threadmill, drilling more and more wells to stay at the same production rate.

Where/when will NG hit the equivalent of $70/$80/bbl oil, I wonder.

If I was a tree I would be scared. Very scared. Natural gas is used throughout the country for heat/cooking. No gas/No heat? Only simple solution would be oil furnace/electricity<--if the grid can handle it/wood.

earth at night: the natural gas burnoff

Postby dduck » Fri 24 Dec 2004, 17:12:58

The sad part of this enormous wastage is that the depletion curve of natural gas fields is typically a plateau followed by a fairly steep crash, rather than the smooth tail-off of an oil field, AND the oil industry seems to be rushing to natural gas as the primary remedy for the coming energy crunch. Plans abound for liquifaction and regasification plants and about 150 LNG tankers already ply the seas, with another 50 or more under construction. It seems that we are setting ourselves up for an energy squeeze on a time scale much more compressed than that of oil.

For some fields yes, but the capital outlay and time required to build a pipeline puts most remote gas reserves off the table. And look at the problems with building them, Afghanistan, etc.

Who gets the gas? Since it will have to be in LNG form, it depends on who has the LNG tanker and ports in place. Last count the US had three ports, I think. China is making many deals for future oil with Iran and most recently, Venezuela. Over the last three months, China has increased oil imports around 30-40%/month from a year ago! 8O

20 years of natural gas at current consumption, yes. That would all change if we suddenly switched to more dependence on gas in place of oil.

I don't know about others here, but i think using nat gas for electricity production is not wise. To me its greatest use is for heating/cooking. How much sense does it make to pipe it to a electricity producer, send it to a consumer, consumer uses it to heat up leftovers?

About the nat gas leakage. I live near(not close!) to a large nat gas pipe(pipes) and every time i walk past them(depending on the wind) you smell it(i know it doesnt have a smell/its the sulfer) and its obvious there is leakage, how much???

Frank,

I agree with you 100%. Consider for a moment how many energy transformations (increased entropy) take place to use natural gas to generate electricity:

Natural gas is used to heat water/to produce steam/the water is used to turn a turbine/the turbine spins a generator/the generator produces electricity/the electricity is sent to a step-up transformer/ it is converted to high voltage/ this is transferred over power lines to a substation/then sent to a step-down transformer/and finally transferred to your house/ where the light wiring (for ease of installation) losses even more energy. Every slash / bar represents energy being transferred from one form to another with a loss of available energy as dictated by the 2nd Law of Thermodynamics (entropy) at each point. These types of units, which use the high heat capacity of water to optimize thermal output, typically achieve 33 to 35 percent of thermal efficiency, meaning that about a third of the heat generated is converted into electrical energy. The two thirds of heat generated that is not used to produce electricity is exchanged with the environment surrounding the plant and is lost as far as function al work is concerned. If you have electric heat, hot water, or a cooktop, the efficiency just goes south, especially in the case of heating water--wasn't that what we started with?

The second traditional method for generating electricity from natural gas is the centralized gas turbines. Gas turbines do not utilize steam but instead turn the turbine with the hot gasses directly produced from combustion of natural gas. Since there is no need to wait for water to be converted to steam, the turbines begin turning as soon as heat is produced from the combustion process. This property lends gas turbines to primarily peak load production where quick electrical production is needed. The cost of this advantage over steam generation units is lowered thermal efficiency(massive decrease in EROEI). Natural gas is used widely in this peak load generation strategy due to its ability to be quickly and easily ignited. Again, a labor and time-saving utilization due to cheapness, that results in great thermodynamic waste.

Many of the new natural gas fired power plants are what are known as 'combined-cycle' units. In these types of generating facilities, there is both a gas turbine and a steam unit, all in one. The gas turbine operates in much the same way as a normal gas turbine, using the hot gases released from burning natural gas to turn a turbine and generate electricity. In combined-cycle plants, the waste heat from the gas-turbine process is directed towards generating steam, which is then used to generate electricity much like a steam unit. Because of this efficient use of the heat energy released from the natural gas, combined-cycle plants are much more efficient than steam units or gas turbines alone. In fact, combined-plants can achieve thermal efficiencies of up to 50 to 60 percent.

If we used natural gas at our home to heat water or cook, we would have only one conversion: gas to hot water or hot food. Whatever solutions we come up with must be focused on decentralization of energy production and point of use applicable to the available local energy. In some places direct heating of water by solar would make the most sense rather than natural gas.

Natural gas normally is non-toxic, tasteless, colorless and odorless. For safety, a scent known as--mercaptan--an acrid chemical, is added so that you will recognize it immediately, should there ever be a leak. Mercaptan makes natural gas smell like sulphur, or rotten eggs. I have no idea how much is loss into the atmosphere due to leakage.

Natural gas is very important fuel, and burning it for electricity, for which there alternative sources, is foolish. It is, for a start, the major source of energy for agriculture - in the form of fertilizer.

However, it wouldn't be done unless there were big advantages.

Natural gas has seen a big increase in its use for 'baseload' generation - the fraction that is always running at maximum capacity, because it provides high efficiency generation of electricity.

I don't know of any natural gas fired steam generation plants - such a system would have an efficiency of about 30-35% and be slow to respond to changes in demand.

The big advantage for gas is gas turbine generation which can offer either better flexibility (with small plants and cost of lower efficiency), or better efficiency (up to 40%) with large plants.

Most new baseload plants are now combined cycle (waste heat from the gas turbine boils water for a steam turbine), and there are plants operating with efficiencies of 58% overall.

Don't forget as well that burning gas at home is not perfectly efficient. If you have an older gas boiler, or water heater, it may well only achieve 70-75% efficiency. If it is of the design which keeps a pilot light lit, or keeps water constantly warm, then overall efficiency could be even lower.

If your boiler is over 15 years old, consider replacing it with a state-of-the-art condensing boiler, efficiencies of 92-95% are possible.

The best options for residential heating would probably be solar thermal (using either flat plat collectors - in warm climates, or vacuum tube collectors in cold climates), or in moderate climates an electrically powered heat pump.

Perhaps in the future, micro CHP will be practical - Small 1-2 kW generator/water heaters could provide residential heat and electricity at high efficiency (>90%). If utilities required a certain percentage of your electricity to be delivered at peak time, then this could be a realistic option for replacing the inefficient small 'peaking' power stations.

"Stranded" Natural Gas to Liquid Fuel, is it time?
$this->bbcode_second_pass_quote('', 'E')very day natural gas flares blaze across swaths of Africa, Russia, Asia and the Middle East, burning off 10 billion cubic feet of energy--the equivalent of 1.7 million barrels of oil. There's more gas where that came from. Reserves of "stranded" natural gas--the stuff that's abandoned because there's no economical way to transport it--come to maybe 2,500 trillion cubic feet. If captured and converted, the gas would make (after conversion losses) 250 billion barrels of synthetics, from clean-burning diesel to jet fuel. That's like finding another Saudi Arabia."
