At What Temperature Does Propane Freeze?

Does propane even freeze? That's a question I happened to ask myself the other day. Let's find out at what temperature propane freezes.

Isn’t it just dandy to have to deal with the cold weather? Sure, some people have the luxury of never having to deal with extremely cold conditions, but not everyone is that fortunate. When it comes to the use of propane (which is a very popular fuel source), users often have the wonder whether or not it freezes. And if that is the case, at what temperature does propane freeze?

We intend to answer that question and a couple more so if that sounds like something you’d be interested in, stick around to find out.

Now, needless to say, propane is such an excellent fuel source for campers. In addition to the fact that some RVs use the gas to fuel appliances, portable grills and such can utilize propane. In other words, if you’re going camping, you’re probably going to want a little propane with you! But enough stalling, right, let’s get to why you clicked on this article today. At what temperature does propane freeze?

Wait… does propane even freeze?

Ah, yes, the million-dollar question that needs to be answered before the true money question. We’ve mentioned a few times of the wonder of what specific temperature it freezes at, but does it even freeze, anyway? It seems like such a stupid question as of course, it freezes, right? Well…it’s complicated, and here’s why.

In a sheer technical sense, propane will freeze if it falls below -306 degrees Fahrenheit. Yes, you read that number correctly and, no, that wasn’t a typo. Now, here’s where it gets a little complicated. Inside a propane tank under pressure, the propane itself actually exists in a liquid state. The liquid will leave the tank at -44 degrees Fahrenheit and then return to its gaseous state.

Therefore, if the temperature is cold enough (and we’re talking well in the negatives), it would theoretically be possible for the propane itself to remain in its liquid form. This would then make it pretty much unusable. In this sense, the answer to the question, “does propane freeze” would be yes.

Whew, does all that make sense? It’s kind of funny because the average propane user won’t have to worry about any of this. However, there is something that can become problematic with propane during colder conditions.

Propane is affected by cold temperatures

So, unless you plan to go camping in Oymyakon (yes, we Googled to see the coldest area on earth and that is what we found), propane is probably not going to ever freeze on you. But wait, you might be thinking, then why does this headline imply that there is still something to worry about? It’s because there is.

You see, propane contracts when it gets cold, and when it gets extremely cold outside, the propane volume inside tanks will shrink. Thus, this will create a loss of pressure, and this can create issues as it may result in the tank not having enough pressure to reach the gas burner. All this adds up to propane that can’t be used, essentially. So, does propane freeze? Yes, technically, but this is what you truly need to worry about.

So, at what temperature does propane freeze?

Okay, so there has to be an answer to this problem, right? Thankfully, there is, and there are ways to prevent the aforementioned issue from even being an issue. Let’s count the ways, shall we?

Keep the propane tank at a certain level

Now, you could ask several different propane companies the same question and each one would probably have a unique answer. That question is how full to keep a propane tank during colder conditions? Some may say 25 percent others 30. We won’t sit here and say it has to be an exact percentage, but just make sure that the gauge on the propane tank isn’t close to empty. Sound good?

Ensure there is no snow or ice buildup on or near the tanks

This one is actually incredibly simple. Yet, that also means it’s easy to allow to slip up, so to speak. No matter the propane tank, as the title says, ensure that snow and ice aren’t allowed to buildup on or around it. Building up around the tank is more so an issue with home propane tanks, as the mechanical components should be free from snow or ice.

Truly, that’s about it. As you can see, it’s really not too tricky to prevent propane from “freezing.” It’s more or less just being cautious about how full the tanks are and keeping them free from snow buildup. Thankfully, this is also only going to be an issue during colder conditions.

Final thoughts

If any of your friends or family members ever ask you, “does propane freeze,” you now know the answer. Showing off your true knowledge, you can also wow them by telling them about the exact temperature at which it freezes. Man, who would’ve known that such a simple question would’ve required such an in-depth look and explanation? Such is the glory of the world that we live in. Happy camping everyone.
