Liquefied petroleum gas (LPG) is a flammable mixture of hydrocarbon gases, primarily composed of propane and butane. It is produced during the refining of crude oil and the extraction of natural gas. LPG is stored under pressure in liquid form, making it easy to transport and use in various applications. LPG is commonly used as a fuel for heating, cooking, and powering vehicles. It is also utilized in industrial processes and as a feedstock for producing chemicals. Due to its clean-burning properties, LPG is considered a more environmentally friendly alternative to other fossil fuels.
