The Difference Between Liquefied Gas and Propane
Different components and different functions.
Propane is a single gas with different compositions, while liquefied gas is a mixed gas mainly composed of butane.
Their ingredients are different. Liquefied gas mainly consists of CH4 and CO, including methane and carbon monoxide. In addition to these, there are many other substances in liquefied gas, such as the odor of sulfides that you can smell when liquefied gas leaks. Among them, there are also many alkanes, which are substances that do not fully convert CH4.
The difference lies in the different ingredients and uses. Propane is a single gas that burns more heat than liquefied gas, and there should be no black smoke emitted during combustion. The flame is light blue and is commonly used as fuel for engines, barbecue food, and household heating systems.
Different uses: Liquefied gas mainly consists of CH4 and CO, such as formaldehyde and carbon monoxide. In addition to these, there are many other substances in liquefied gas, such as the odor of sulfides that can be smelled when liquefied gas leaks. There are also many alkanes, which are substances that do not fully convert CH4.

The Difference Between Butane and Propane:
The molecular structure of butane and propane
The molecular formula of propane is C3H8, while the molecular formula of butane is C4H10. It can be seen that butane has one more carbon atom than propane. This means that the molecule of butane is larger and heavier than that of propane. In addition, propane molecules are a straight chain, while butane molecules can have a straight chain, branched chain, or cyclic structure.
Physical properties of butane and propane:
Due to the fact that butane molecules are larger than propane, butane has a higher melting point, boiling point, and density than propane. The melting point of butane is -139.4 ℃, the boiling point is 0.9 ℃, and the density is 0.573g/cm ³； The melting point of propane is -18.6 ℃, the boiling point is -42.1 ℃, and the density is 0.493g/cm ³。 In addition, due to the fact that butane molecules can have linear, branched, or cyclic structures, different structures of butane may have different physical properties.
In summary, although butane and propane belong to similar hydrocarbons, their molecular structures, physical properties, and uses are different. By understanding their differences, we can better apply them and better understand their role in practical applications.
Differences and Relative Advantages of Propane, Butane, and Liquefied Petroleum Gas
Propane and Butane - Environmental Choice
Propane, liquefied petroleum gas, and butane are all liquefied petroleum gases. Usually, the acronym LPG and the word propane can be interchanged, with propane being the preferred term in the United States and LPG being the preferred term in Australia and New Zealand.
At -42C and -0.4C, the boiling point of propane is lower than that of butane. The vapor pressure of propane is also about 4 times that of butane. This makes propane a better choice for cold climates. Due to its lower vapor pressure, butane is an effective propellant. In other aspects, butane and propane are the same. Although there is a real difference between butane and propane and liquefied petroleum gas, all three gases are actually liquefied petroleum gas - liquefied petroleum gas.
Understanding the boiling points of butane and propane:
The most important difference between propane and butane is the boiling point of the gas. The boiling point of propane is -42C, while the boiling point of butane is -2C. This means that propane will continue to evaporate and convert into gas in colder climates, which is very suitable for cold weather and outdoor use. When stored in liquid form in tanks, propane exerts greater pressure than butane at the same temperature. This makes it very suitable for external storage.
The impact of propane gas and butane gas on emissions:
Propane and butane are clean energy sources that emit minimal pollutants or harmful refrigerants. They are low-carbon and safe for transportation. The improvement of propane utilization efficiency and the reduction of harmful emission fuel sources will help improve air quality, reduce greenhouse gas (GHG) emissions, and protect the environment. Here are some advantages of propane.
Reducing harmful emissions - Propane is a clean and widely used fuel. Propane emits 26% less greenhouse gases (GHG) in cars than gasoline, 38% less than fuel oil in furnaces, and half as much carbon dioxide (CO2) as charcoal grilling.
Propane is an ideal fuel source for household appliances and a perfect partner for transitioning to renewable energy supply:
Reducing pollution - Air pollution affects both natural and man-made ecosystems worldwide. Air pollutants can cause ground ozone, haze, and acid rain. As is well known, poor air quality can lead to a series of major health problems. Using propane instead of other common fuels will reduce air pollution.
Propane emits 60% less carbon monoxide (CO) than gasoline, 98% less particulate matter than diesel, and is almost sulfur free. Sulfur is the source of acid rain.
No leakage hazard - Propane (LPG) cylinders are sturdy enough to handle regular movement and transportation. In case of a leak, propane will turn into a vapor and quickly dissipate into the atmosphere. This is important when operating in environmentally sensitive areas.
No escape emissions - "escape emissions" refer to gases that escape into the atmosphere before combustion. Propane is a wise environmental choice because it is not a greenhouse gas and if accidentally released before combustion, it will not affect the atmosphere.
On the other hand, natural gas (methane) is a potent greenhouse gas in its unburned state. During the transmission process before use, up to 5% of natural gas will be released. This unburned methane has a greenhouse effect on the atmosphere 25 times that of carbon dioxide.
Common uses of propane gas and butane gas:
Propane (liquefied petroleum gas)
Propane has a high octane number, making it an excellent choice for spark ignition internal combustion engines. If spilled or released, it will not pose a threat to soil, surface water, or groundwater.
Propane is a byproduct of natural gas processing and crude oil refining. Its main uses include household heating and independent heaters, hot water, cooking, refrigeration, clothing drying, and power supply for farms and industrial equipment. The chemical industry also uses propane in the manufacture of plastics and other compounds.
Butane:
Butane is a highly flammable hydrocarbon gas. It is colorless, odorless, and easy to liquefy. Butane is commonly used as a fuel for lighters and portable stoves. It is also a propellant, heating fuel, refrigerant in aerosols, and used to manufacture various products. Butane is also present in liquefied petroleum gas (LPG).
Since 1987, hydrocarbons have replaced chlorofluorocarbons (CFCs) as the most commonly used propellant in aerosols. Today, butane is present in many aerosol products. Butane burns very well in warm weather. However, when the temperature in high-altitude areas drops sharply below freezing point, it is best to choose propane with much lower boiling points.
