    My water is flammable. very flammable! im talking tourch from the faucet flammable. lol. has anyone heard of anyone collecting natural gass from their water well and using it for cooking or to run a generator or something of the like. id love to be able to use the gasses to get off grid, not to mention being able to stop to awful water hammer in my water pipes.

    You will be better off ventilating the well house and putting a small treatment plant to degas your well water before it gets to the faucets. All the harm it will do will happen if you try to capture it with less than an industrial lashup. Go here Natural gas leasing and production information for landowners
    and prowl around, then do a web search on "Dimock, PA" on line. Generally, gas in the water is not harmful by itself.

    Also understand that if you do NOT Own the SubSurface Mineral Rights, to your Property, you can be sued by the Owner of those Rights, for Thieft of Their Gas.... If you DO happen to Own those Rights, contact your Local Natural Gas Company, and see if they would be interested in Leasing those Rights from you, and supplying some of that Gas to you as part payment for the Lease...

    Yes, but, and it's a big but. The Rule of Capture may apply as well.

    @ghrit is correct with regards to the treatment equipment. A small separator unit would be ideal. Not sure if one small enough for you is readily available as I have only built the larger ones used in the oil/gas fields of the west.

    Oil and gas separators -

    This all may look complicated but once you understand the process, a person should be able to fabricate their own if they have metalworking skills.

    We own the mineral rights down here...or at least after 7 years or cessation of production.
    I would put a metal cylinder over the well or inline with a valve at the top allowing the nat.gas to rise to the top, After that do what you wish.

    A friend of mine has natural gas on his property. His difference is it comes out of the ground at 140 psi and all he does is run it thru a pressure regular and plumbs it to his and his son's homes' furnaces and a genset.

    Don't know if you are in the country and have space or not. There are low pressure capture and storage systems using large bladders etc. that are used with methane generation systems operating on some farms based on manure. Most of these are on dairy farms and some hog operations. The manure goes into a large diameter shallow tank, often in or partially in ground, and the decomposition yields methane. Goggle that stuff and see what you find.

    If the extraction rate of gas from well is within the consumption rate of your furnace little storage would be required. If not, then storage needs increase to save up say during the afternoon when consumption might be lower to use a night when it is colder. Low pressure bladders would handle that. Now if you need to save up during the summer to burn in winter, then storage costs may not be worth the savings.

    Are you sure about the 140 PSI on that gas .
    Gas normally produces about 5 PSI on it's own .
    very curious about this.

    Gas generated in surface tankage like digesters will produce in the inches w.c. to very low psi ranges, depending. Fully operational commercial grade shale gas wells will produce at 1000+/- psi, pipeline ready. I'm far less sure of commercial grade producer pressures in sandstone formation, but would be very unsurprised to find them showing much higher pressures than the140 psi cited above. Now, if the well has been abandoned by the operator due to depletion, there will certainly be residual gas that can be harvested. Under that set of conditions, I would not be shocked to hear of 140 psi at the surface.

    I'm not challenging your info ,but as a practice, acetylene gas must be mixed in acetone and carbon to achieve high pressures,
    other wise it will explode on it's own over 20 PSI or so .
    I guess it is all about the molecular structure of the element.

    The problem with acetylene is the triple covalent electron bond between the 2 carbon atoms. It's very unstable.
    Only other substances I know of that have triple covalent electron bonds are very unstable in atmosphere.

    Acetylene explodes when compressed beyond 29psi.

    That's why you run acetylene pressure in the hose to your torch as low as possible, usually 2 to 5 psi. And you should have flash back arrestors on your torch and regulator.

    If acetylene was discovered today it would be considered so dangerous we likely wouldn't even try to use it.

    Your info is pretty close. Note that if acetylene was transported under pressure, there wouldn't be much gas in a bottle. That's what the acetone does for you, it dissolves and stabilizes the acetylene so much more gas can to into the bottle.
    @oil pan 4 - We might still use aceylene, but it would have to be locally generated. Think carbide lamps.

    If calcium Carbide were not so expensive I'd be storing it like coal or fire wood .
    I have old carbide lights and use the Oxi/acetylene torches often enough, making a generator for the gas would be worth while .
    If you think about it Acetylene stove might actually be a good idea. All you'd need to cary is some calcium carbide. any water will do.

    Some people are switching to oxy propane for cutting since propane is cheap acetylene is getting more and more expensive.
    If you think about it the flame on a cutting torch is kind of only a pilot light. All you need the flame to do is heat the edge of the steel to about 1,600°F and the stream of oxygen takes care of the rest.
    On thicker steel once you get the cut started you can actually turn the acetylene off and keep going.
    Main advantage acetylene has over propane is on thinner steel seems to make a cleaner start and acetylene will heat the steel up a little faster on the thicker stuff.
    But I'm pretty sure that you have to use acetylene to torch weld steel and acetylene will heat stuff up faster than propane.
    Acetylene is better in cold conditions too.
    Propane has an much higher withdrawal rates for the size of the container, if it's warm out.

    Ah the good old days....not a few letterboxes were destroyed back in the day with carbide bombs....it's a miracle no one was killed or badly injured.
