Frozen Methane Recovery

01/09/2009 9:31 AM

What about utilizing frozen methane. If we can recover oil from 10-15,000 feet, why

can't the frozen methane be recovered?

Because it quickly melts and turn into water and lighter than air gas that will in any case rise and the cost may be higher than the value.

Maybe yes AND maybe not. The beauty of methane clathrate is that it is not forming too shallow, but definitely does not form deep. Some norwegian studies show, it can be transported with minimal losses in cooled carriages.

Additionally, the last recent survey indicates it being TWICE IN AMOUNT OF ALL OTHER CARBON BASED FUELS ALTOGETHER. The rest reminds me of a baby: no matter how many men you throw at the problem, the answer is still 9 months. Research cannot profitably be accelerated.

You do not like it? The world we are living in could not care less, nor could I. To top it,the world does not even cares about MY wishes. So, get on with it. Or get thrown under the bus energy vise, I do not care. You think, your views win out, when people are freezing?? I already have taken out bets on that in a Las Vegas betting parlor. So, go ahead with the bet, make me rich.

What is this all about??? you were not insulted. There is no need for such talk. Please remain civil. It is one thing for you to be passionate, and quite another to be so insulting to people. These discussions will remain on here for a long time...

Methane Hydrates is being explored as a future source of fuel. As of yet the have no means to harvest it in great quantities yet.

How deep is it? Plenty of people are aware of it, but I don't know what the problems are in mining it. There is also a lot of methane coming up from tundra.

Besides it is tricky to extract. Cavitation can turn to expanding gas that rises rapidly forming a low pressure area below it forming more gas in a chain reaction. Any vessel and even oil rigs on this out gassing can quickly sink.

Not impossible just not easy.

Many experimental devices have been developed and tried. So far they have not been successful. Operating 'mining equipment' in deep ocean waters is NOT a trivial undertaking. Even more problematic is the somewhat unpredictable dissolution of methane from the hydrate. A reliable means of capturing the methane is necessary to avoid sinking the vessels on the surface if methane escapes into the water--vastly reducing the density of the resulting froth. This would cause the vessel to sink completely almost instantly.

The formation of methane clathrate is temperature and pressure dependent. I happen to know two data from he top of the head: the Scientific American had it on the front page just a few years ago, in the Gulf, south of Mississippi. Inches long worms were living on the interface of methane ice and water (yes, virginia, it is that cold deep in the ocean). The other data is, that in the arctic ocean, and the nordic tundra of Canada, Russia and Alaska it is forming 10 meters down and lower both in the ocean and land. Present day experimentation is - obviously - done there.

This is where experimentation is done. Will they succeed? I have no idea, but the need is there. Make your bets and proceed from there. The Athabasca Tar Sands were treated the same way for a looong time, and now it is an economical setup, only dependent on the proper oil price.
