Does Propane go bad?

You can also get the tank recertified. Most folks just don't bother and just buy a replacement at a higher cost than recertification.
You can also buy a stamp kit from Harbor Freight and recertify the tank yourself. A 100 lb. tank is the largest considered "portable" and expires after 12 years. Do a thorough inspection of the tank for damage, and particularly for rust on the bottom. State law often requires valve replacement, which can be done by using a propane torch to soften the Loctite on the threads. Even if you use the original valve, inspect it carefully. I have seen a valve seal deteriorate and fail to seal, creating a severe fire hazard. On the one I saw, the seal was not replaceable. It needed a new valve.

Here is what recertification marks look like:

Whatever the average person does for the above they'll be doing it Neked or nearly Neked .

Oh I think we'll be using fuel and propane in a hundred years but it might be the fact that much will not be extracted from buried reserves.

Maybe some people here know, and after all the seemingly endless issue to get even planes to run on bio fuels ... what annoyed me a couple of years to no end was discovering that the refinery plants, can use vegetable oil stock, in the same cracking plant as it exists ... to produce the same product we're putting in our tanks right now! No the oil industry doesn't advertise that what so ever. My guess is what will come to pass is "the industry" will finally announce they can do something with natural non mineral oils ... no doubt charging a big fee for this "new" technology they'll introduce.

Electric works quite well for cooking and heating. Is far more efficient for heating with heat pumps. Geothermal ones will work anywhere. Already have heat pumps for hot water and for clothes drying, lots more efficient than gas or straight electric.

And…who will pay to convert everyones houses? Where are they building new electrical generating plants?

Geothermal would pay for itself if you're using either straight electrical heating or heating with NG or propane/butane. Saves at least 2/3.

They just got approval for a 3900 acre solar farm at Christmas Valley. Five new wind projects launched in 2021. Wind already supplies 82 gigawatts, and is growing fast.


States spending the most on wind power projects over the next 10 years:​

  • Texas is the state that will invest the most in wind energy, with spending estimated to rise to $16bn on 26 projects in total.
  • With spending estimated to $15bn, Massachusetts will create job opportunities in 6 new projects.
  • With a cumulative investment through 2019 of $4.2bn, New York will build 18 new projects with spending estimated to $11bn.
  • Wyoming will invest in 10 new projects with a total value of $9bn.
  • New Mexico, where the installed wind capacity is 1,952MW, spending estimated to $6bn in 8 projects.

Yep, the new environmental disaters. And what happens when the sun isnt up or the wind dies off? 3900 acres being clearcut and thats a good thing? How many govt subsidy dollars are propping up these pet projects?

“While we humans get most of our carbon from food, trees breathe it in (just like we breathe in oxygen). But when a tree breathes, it inhales carbon dioxide and exhales oxygen — the exact opposite of humans. And as a tree matures, it can consume 22lbs of carbon dioxide per year (among other greenhouse gases like ozone), and release enough oxygen for you to breathe for 2 years!” https://onetreeplanted.org/blogs/stories/planting-trees-reduce-carbon-footprint

Geothermal heating for a residence consumes more electricity and typically has a 20+ year ROI.

I'm sorry. You're wrong. There's a 3 to 4 COP for geothermal. It will save 2/3 to 3/4 of the energy compares to straight electric or NG/propane. Bet the ROI is much better than 20 years.

:ROFLMAO: :geek:😂 You saw a tree? Where? Even the juniper dies of thirst in that area. Nobody would complain about clear cutting 3900 acres of Russian thistle, AKA "tumbleweed." Oregon has extensive land use laws, and the project got approval because that land grows precisely nothing. The big ecological concern was if all the lizards and snakes would have to relocate. It's in the middle of a huge desert.

They recently invented things called "wires" to move electricity around. The wind is always blowing somewhere.

I spent a year in Glennallen, AK. Good Morning - Doofy. Everything was run on propane. Electricity was more expensive than GOLD.

Never had any propane "go bad". BUT - it would get so cold - the propane would loose its pressure and not flow. Propane had to be in a heated shed or some form of heated enclosure.

Yep, our regulators would freeze up between -40 and -65. We would have to pour hot water over the regulator while holding your finger over the screened vent. We also would throw an old piece of fiberglass insulation over the tank with a light bulb under it.

Haven't had any problems since the advent of Global Warming...just doesn't get that miserably cold any more.😁

I agree, global warming is a good thing!

Ethyl Mercaptan (the odorizer in propane) is heavier than propane and can possibly seperate out if not used for a long time. Or can be absorbed by rust in a tank. So you may not have the safety of being able to smell a leak under various conditions.

I'm curious, do you have any data for ethyl mercaptan actually separating from LPG/propane?

I can't find any. (Bad Google-fu?)

Because the densities are so close, and the amount of mercaptan so low (1lb/10,000gal) that separation seems improbable to me. (Newton's 3rd law and all that.)

Part of the reason that ethyl mercaptan is used is because it is so resistant to degradation.

All the best,
