What is Propane?

Propane is commonly called Liquefied Petroleum Gas (LPG). It is an odorless, non-toxic, colorless gas that has been compressed and stored in its liquid form inside specified tanks. Also, it is a by-product of petroleum refining or natural gas processing.

What does natural gas processing involve? The process involves the removal of Propane, butane, and ethane from raw gas in large amounts so that they cannot condense in natural gas pipes. Also, Propane can be a by-product of the cracking process, which involves the conversion of petroleum to gasoline or heating oil.

What is Propane Gas Used for?

Propane is used for many purposes, both residential and commercial. For instance, you can use it for cooking, gas fireplaces, water heating, home heating, and as the primary energy source.

For outdoor purposes, Propane can be the perfect fuel for BBQs, lighting, pool heaters, outdoor kitchens, backup generators, patio heaters, and even outdoor camping kitchens. This is possible because propane tanks are efficient, powerful, and portable. Also, some people use Propane as vehicle fuel, popularly called propane autogas.

Apart from home, propane gas is used for commercial and construction purposes in propane-powered equipment such as concrete grinders, lawnmowers, polishers, and forklifts, among many other appliances.

Does Propane go Bad When Stored?

Propane gas does not go bad when stored. This gas is known to be very different from the other fuel gases that go bad after some time of use or storage.

As mentioned earlier, these tanks always have an expiration date on the outside. You should know that this date does not mean the gas has expired, but it reminds you of when you should change your tank. The tank is the only thing that can be inspected and changed, as the gas is always good.

When Does Propane go Bad?

The fact that it does not have an expiration date means that your gas won’t degrade or reduce its performance rate.

Shelf Life Propane

The shelf life of Propane is among the things that make it a reliable gas. It rates top among all other gas fuels such as diesel and gasoline. Further, Propane is usually reused for both residential and commercial purposes.

All other fuel sources have a limited shelf life, but Propane lasts up to 30 years when well stored in its tanks. This is almost saying that Propane does not have a limited shelf life. However, the tanks used for propane storage are the ones that might affect the gas’ shelf life.

Propane’s Unlimited Shelf Life.

As mentioned before, the storage tanks for Propane are the ones that can limit its shelf life. However, three decades is still very long for a fuel gas to stay viable, considering that the other gases have a concise shelf life. Even if Propane gets exposed to other elements, it does not downgrade or perform less than expected.

Apart from being reliable, Propane is associated with many other benefits, such as being odorless and clean. Consequently, most people today prefer using Propane over other cheap fuel gases. Also, its longevity makes it easy to transport and store.

How Long Does a Propane Tank Last?

A propane tank’s shelf life varies from brand to country, among many other factors. However, in most states, a propane tank can last for up to years from the day of manufacture.
