Propane gas – Common uses, facts, and things to know

  • by

In the previous blog, we saw what is propane gas, its chemical properties, where it comes from, and other things.

Today we will cover some topics like the common uses of propane, important facts, etc. let’s move ahead.

Where is propane gas commonly used?

Propane is used in everyday life, just that we might not be aware of. It is used in heating, water heaters, cooking, gas fireplaces, and clothes drying.

Propane is also used in propellants, refrigerants, petrochemical feedstock, and vehicle fuel applications.

Propane gas is one of those which can be used in leisure activities such as caravans, recreational vehicles, hot air balloons, recreational vehicles, and camping. It is also used in many commercial and agricultural heat applications including commercial boilers.

Listed below are some agricultural applications of propane:

  • Crop and produce drying
  • Heating greenhouses
  • Hot water for dairies
  • Irrigation pumps and
  • Heating animal enclosures

Propane applications are very vast, counting them down would definitely take ages – it includes power generation and the hospitality industry.

Now that we also have read that propane is a commonly used fuel – but why is it used?

Since Propane gas has a high energy density and is used as a fuel because of its portability. Propane is such a gas that requires very little pressure for liquefication – that helps to maintain a practical vessel weight.

Hence, propane is used as a fuel for transportation.

All of this can be useless for some people around if they don’t get any facts about Propane Gas. Let’s have a look.

  • Propane is LPG, but not all LPG s propane.
  • Propane gas is a flammable hydrocarbon that is liquefied through pressurization – and commonly used as fuel.
  • It can be compressed into a liquid at relatively low pressure.
  • Stored as a liquid in steel vessels, propane gas ranges from small BBQ gas bottles to large gas cylinders and also storage tanks.
  • Propane gas is obtained from natural gas and petroleum refining.

Done with facts. Shall we see some properties of propane?

Boiling Point

  • Water boils at 100oC and turns into steam
  • On the other hand, Propane boils at -42oC becoming gas vapor.
  • Under a particular pressure which is inside a gas cylinder – propane stays in liquid form.
  • It is hard to distinguish between water and liquid propane as it looks like water.
  • In its original state, it is colorless and odorless.

Addition of Odourant

propane gas odor

  • Since propane gas is odorless, the distinctive smell that people can make out is actually added to it for safety measures.
  • Without any odourant – leaks of propane gas cannot be detected.

Avoid Direct Contact

  • Liquid propane is cold at an extreme level.
  • It can cause severe cold burns on exposed skin.

Density of Propane

  • Unlike water, 1KG of propane is not 1 liter of propane.
  • Propane’s density or specific gravity is about half of water – it is 0.51
  • 1KG of propane has a volume of 1.96L.
  • In contrast, 1L of propane weighs 0.51KG.
  • 1lb of propane @60oF has a volume of 0.24 US Gallons.

Gaseous Expansion

  • It expands to 270 times the volume when it converts from liquid to gas
  • This also means 1L of liquid Propane is equal to 270L of gaseous propane.

Energy Content of Propane

  • Propane contains approximately 25MJ per liter
  • When converted into kWh it is 6.9kWh
  • 1 US gallon of propane = 91,502 BTU @ 60ºF
  • 1ft3propane gas = 2,488 BTU of Gas @ 60ºF
  • 1 US gallon propane = 1.1 therm
  • Therm 1 = 100,000 BTU
  • 1 watt = 3.41214 BTU/h

Let’s go into chemistry now, have a look at the combustion formula

In the presence of sufficient oxygen, propane burns to form water vapor and carbon dioxide, as well as heat.

Propane + Oxygen → Carbon Dioxide + Water + Heat

(C3H8 + 5 O2 → 3 CO2 + 4 H2O + Heat)

As said propane gas is highly flammable, and y’all know what flames can do – damages!

It’s always better to be prepared for such unsaid situations that can be harmful. Fire safety is one major thing to keep in mind.

And when it comes to fire safety, to prevent the initial fire from spreading a fire extinguisher ball is someone who can help you save your precious things.

After all, it’s going to be your call. And what would you prefer, fire burns over fire safety?

 

That’s all folks!
See you all in the next blog.
