Propane: 85% min. by liquid volume Propylene: 5% max. by liquid volume Butane & heavier HC: 2.5% max. by liquid volume Sulfur: 120 ppm max. by weight LPG stands for liquefied petroleum gas, also known as propane or butane. It is a flammable hydrocarbon gas that is commonly used as fuel for heating and cooking in homes, as well as for industrial applications, transportation, and agriculture. LPG is a byproduct of crude oil refining and natural gas processing. It is a mixture of propane and butane gases, which are liquefied through pressurization and cooling. LPG is stored and transported in pressurized tanks and cylinders as a liquid, but when released into the atmosphere, it vaporizes into a gas. LPG is a versatile fuel that has many advantages over other fossil fuels. It is clean-burning and produces fewer emissions than gasoline or diesel, making it a more environmentally friendly fuel option. It is also highly efficient, as it has a high energy content per unit volume, and can be easily transported and stored in liquid form. LPG is widely used around the world, particularly in areas where natural gas pipelines are not available or where electricity is unreliable or expensive. It is commonly used in households for cooking and heating, and in vehicles as an alternative fuel to gasoline or diesel. LPG is also used in industrial applications such as manufacturing, agriculture, and chemical processing.
