What are the applications of the C3H8 gas

  • Propane C3H8 combined with C4H10 butane gas will form liquified petroleum gas called LPG. LGP has wide application as a main source of energy for industrial production as well as in households. C3H8 gas is used as a fuel for a wide variety of heating, commercial, agricultural, and even cooking applications.
  • C3H8 propane gas is also used as a propellant, a quick refrigerant, a fuel for automobiles, and as a petrochemical raw material.
  • In addition, propane C3H8 is used extensively in various high-end recreational activities including yachts, recreational vehicles, hot-air balloons and camping.
  • Industrial businesses use C3H8 for different processes including boilers, furnaces, ovens, and forklifts.
  • Agricultural heating applications of propane: Applications for the reclamation, manufacturing, drying and heating of greenhouses, hot water supply for dairy plants, irrigation pumps and animal tanks

  • Transportation: This is also an industry that uses large volumes of propane. It can be used alone or mixed with butane to provide fuel for different vehicles.
  • There are also many other highly regarded applications of C3H8 including power generation and hospitality use.

Some other uses for propane gas C3H8

  • C3H8 is the main gas used in the welding industry.
  • Hot air balloons use Propane as the primary fuel.
  • This gas is used in the manufacture of semiconductors to sediment silicon carbide.
  • Propane is also used in amusement parks and in the film industry as a low-cost, high-energy fuel for explosions and other special effects.
  • Propane is used as a propellant to fire bullets based on gas expansion and does not burn the gas.
  • Propane is used as a handy propellant in many household sprays, including shaving cream and air coolers.

Some summary information about propane C3H8

What is Propane C3H8?

Propane C3H8, or propane, is actually a carbon compound with the molecular formula C3H8.

Propane exists in gaseous form at standard temperature and pressure. But it can be compressed into a liquid for easy storage and transportation. Like methane, propane also belongs to the alkane isotropic series with gases such as: Butane, Methane, …

Propane C3H8 gas is a byproduct of oil refining and natural gas treatment. It is often used as a fuel for thermal applications.

C3H8 is a component of the liquefied gas (LPG) groups. Others of this group are butane, propylene, butylene, butadiene, isobutylene, and their mixtures.

Some summary information about propane C3H8

Propane C3H8 is LPG but LPG is not propane. LPG is the English acronym for Liquefied Petroleum Gas.

It is a flammable hydrocarbon gas which is liquefied at relatively low pressure and commonly used as a fuel.

Propane is produced from the natural gas process and oil refining process.

Propane C3H8 is usually stored and transported as a liquid, stored in steel bottles or tanks.

Propane C3H8 gas currently has many different names

In Australia: Propane C3H8 is also known as LPG, LPG Gas, BBQ, LP Gas Gas or Autogas.

In America it is only called Propane.

In Vietnam, Propane C3H8 is often called Gas, in gas industry it is called Gas C3H8 or Propane

How does Propane C3H8 work principle?

Propane C3H8 is stored as liquid in an air tank under low pressure.

It quickly returns to a gaseous vapor when the user releases the pressure in the gas tank.

How was C3H8 detected?

Where and how was C3H8 detected?

Propane C3H8 is formed as a byproduct of two different processes: natural gas treatment and oil refining.

Treatment of natural gases involves the removal of butane, propane and large amounts of ethane derived from the raw gas

In addition, propane in refineries is a byproduct of heating oil or cracking oil into petroleum.

Properties of Propane C3H8 gas

Propane C3H8 is colorless, odorless in its natural state and smells of petroleum but quite faint. This smell is added to increase safety. If there is no odor, the gas leak is difficult to detect.

It is easily transported as a liquefied gas under vapor pressure. Flammable, liquid in pressure containers.

Propane C3H8 boils at -42 ° C and then becomes gas vapor.

Propane in liquid form looks like water, but propane is insoluble in water because of its chemical nature.

This is a hydrocarbon gas that has nonpolar bonds, unlike water which has polar bonds. Thus, there is a relationship between the same type of association and the repulsion between the different associations.

When using this gas, please be careful to avoid direct contact because liquid propane can cause severe burns to our skin  when directly touching.

Propane’s energy

Propane’s energy is about 25 MJ / liter which is equivalent to an energy level of 6.9kWh.

Burning formula

Propane fires occur in the presence of sufficient oxygen that produces steam, carbon dioxide and heat. When properly burned, a fully burnt flame will be blue and its fire is at 1980ºC (3596ºF).

Propane + oxygen → Carbon Dioxide + Water + Heat

(C3H8 + 5O2 → 3CO2 + 4H2O + Heat)

If there is not enough oxygen for complete combustion to take place, carbon monoxide and carbon dioxide will be formed. A sign of inadequate burning is a yellow or red flame.

Flammability limits of propane

The lower and upper for a certain type of gas are: the percentage of the gas that must be present in the mixture of propane / air.

This means that at the flammability limits between 2.15% and 9.6% of the propane / air mixture, propane C3H8 ignites easily

The flash point of propane or the minimum temperature at which propane will ignite is -104ºC (-155,2ºF).

When it is below this temperature, Propane will not ignite on its own. However, if a source of continuous fire occurs, it will burn below -104 ° C.

Propane exists as a gaseous form heavier than air and will sink at its lowest point.

Propane exists as a gaseous form heavier than air and will sink at its lowest point.

If propane C3H8 is vented into outside air, it will quickly dissipate and be emitted with slight movement of air.

Conversely, if the propane gas is absorbed or injected into a closed structure and there is no moving air, it will slowly sink, survive on the floor and move gradually into closed cavities.

Propan gas is toxic or not?

This gas is an combustion fuel that serves many different purposes. However, the accumulation of propane C3H8 gas in a confined space can cause an explosion or fire with a minimal spark. It can cause injury, property loss and also human damage.

And propane gas is usually pumped into the cylinders or tanks containing C3H8 gas in the liquid form and appears more in the form of gas and presents in many households.

The tanks subject to high pressure can break and cause explosions. And even if this gas is not burned, the propane C3H8 accumulation can cause difficulty in breathing, suffocation and death due to lack of oxygen.

Therefore, you need to be aware of the potential dangers that can occur when using propane C3H8 incorrectly. To minimize unwanted injury and death please choose a reputable unit to buy high-quality C3H8 propane gas tank.
