What is the difference between natural gas and liquefied gas?

The difference between natural gas and liquefied gas: 1, different definitions: natural gas refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the stratum. Liquefied gas is mainly a mixture of hydrocarbons. 2. Different components: the main components of liquefied gas are butene, propylene, butane and propane, while the main components of natural gas are alkanes, and methane accounts for the vast majority. 3. Different application fields: Natural gas can be used not only as fuel, but also for clean energy vehicles, industrial cutting and power generation. Liquefied gas is mainly used as petrochemical raw materials and can be used as fuel for industry, civil and internal combustion engines.

4. Different safety: Natural gas is one of the relatively safe gas. Once it leaks, it will spread upward immediately, and it is not easy to accumulate and form explosive gas. Liquefied gas is a flammable substance. When the content in the air reaches a certain concentration range, it will explode when it meets an open flame.

When natural gas leaks, put an end to open flames.

Natural gas is easy to mix with air to form explosive mixture, and the explosion limit is 5% to 15%. After natural gas leaks, because it is lighter than air, it will quickly gather in the upper part of the room. At this point, we must first put an end to all kindling, quickly close the pipeline door, then open the doors and windows, and fan the natural gas floating in the upper part of the kitchen with fans and other items, but never open the exhaust fan and range hood, because it is easy to cause electrical ignition and explosion. Then notify the service personnel of the gas company to come and deal with it, so as to repair the gas leakage in time.

Prevent explosion when liquefied gas leaks.

The leakage of liquefied gas is very dangerous. Because it is liquid in the cylinder, it will expand 250 times immediately after flowing out. Because of the large proportion, it does not float but sinks to the ground after leakage, and accumulates in low-lying places, which is not easy to float and has a low explosion limit. Therefore, after putting an end to all kindling, closing the cylinder door and opening the doors and windows, gently sweep the floor with a broom, blow out the leaked liquefied petroleum gas and paint it with silver to prevent the kindling from exploding.
