Liquefied petroleum gas characteristics
- Nov 08, 2017 -

The characteristics of liquefied petroleum gas have the following points:

Volatile At room temperature and pressure was gaseous, liquefied petroleum gas liquid immediately after the release of volatile gas. Gasification volume expansion of 250 to 300 times and the rapid proliferation of proliferation, that is, 1 liter of liquefied petroleum gas can be volatile into more than 250 liters of gas. Liquid-phase liquefied petroleum gas also has a larger coefficient of expansion, typically more than 10 times that of water, so liquefied petroleum gas cylinders are prohibited from being heated and overfilled to prevent explosions.

Flammable, explosive The explosion limit of liquefied petroleum gas is 1.5% ~ 9.5%. The lower explosion limit is also more dangerous and can be detonated by small Mars.

3, the relative density. Liquefied petroleum gas is heavier than air (relative density is l.5 ~ 2 times of air), easy to stagnate and accumulate in the low-lying floor, sometimes not easy to be blown by the wind, easy to mix with air to form explosive substances, will meet the fire source will explosion.

4. Toxicity. Liquefied petroleum gas is colorless and transparent and has a special odor of hydrocarbons. It is harmless to human health when its concentration in the air is less than 1%. However, prolonged exposure to liquefied petroleum gas (LPG) at higher concentrations can cause unconsciousness, vomiting and may suffocate or even cause death in severe cases.

5. High latent heat of evaporation. Liquefied petroleum gas (LPG) needs to absorb a lot of heat when it changes from liquid to gaseous state. If the liquefied gas tank or pipe valve leaks, the liquefied gas may cause frostbite if it is sprayed onto people.

6.Low corrosiveness Low sulfur content of liquefied petroleum gas, generally non-corrosive, but can soften the rubber.

Liquefied petroleum gas is used for a wide range of purposes and can be used as fuel for civil and industrial use. It can also be used as a raw material for synthetic resin, synthetic rubber, synthetic fibers and fertilizers. It is widely used in industry and agriculture for drying, baking, food, , Hatching chickens and ducks, feed processing and welding cutting, melting of metals, quenching and annealing, bending, such as forging. Liquefied petroleum gas is closely related to people's life. With the development of science and technology, liquefied petroleum gas is used more and more widely.
