The answer to the question, What is propane?

What is propane gas. That is the question we are going to answer. Because in an earlier blog we already told you that propane gas was an interesting alternative to natural gas. Yet, in practice, there are often questions that remain unanswered. What exactly is propane or propane gas, what does it smell like and how is it extracted?

What is propane?

Propane, the liquid form of propane gas, is a hydrocarbon gas with the chemical formula C3H8. It is extracted as a byproduct of natural gas extraction and petroleum refining. Propane gas is liquefied into propane by pressurizing it. This process, known as liquefaction, reduces the volume of gaseous propane and makes it easier for us as propane gas suppliers to transport as well as store it. At normal pressure and temperature, propane is a gas, but when brought below a pressure of about 1.7 bar, it becomes a liquid. It is often used as a fuel for domestic heating, stoves, vehicles and as a raw material for chemicals.


Does propane gas have a specific odor?

The short answer to this is: no. Yet you do smell propane when there is a gas leak. Why is that? Propane originally has no specific odor. Therefore, artificial odor is added. This is done to ensure that it can be detected when a pipe leaks. In this way, large gas leaks are prevented. The artificially added odor is often described as a "rotting egg"-like smell

What is the difference between propane and butane

  • Propane and butane are both hydrocarbon gases that occur as by-products of natural gas extraction and petroleum refining. However, they have different chemical formulas and properties:
  • Propane has the formula C3H8, while butane has the formula C4H10. This means that butane has one more carbon atom and 2 more hydrogen atoms than propane.
  • Propane has a lower boiling point than butane, this means that propane as a gas changes to a liquid at a lower temperature.
  • Propane is lighter than butane, making propane more suitable for transportation and storage in liquid form.
  • Butane has a higher burning point than propane, this means that butane must have a higher percentage of gas before it ignites.
  • Propane is often used as a fuel for domestic heating, stoves, vehicles and as a raw material for chemicals. Butane is mainly used as fuel for gas lanterns, gas cylinders and small gas burners.

Is propane sustainable compared to natural gas?

Propane gas and natural gas are both fossil fuels and both fall under the group of hydrocarbons. Combustion releases water and carbon dioxide (CO2). What makes propane through OK GAS sustainable is that OK GAS offsets the CO2 produced by the propane sold and used by participating in projects that then offset that CO2.
