Flüssiggas, also known as liquefied petroleum gas (LPG), is a mixture of propane and butane. It is produced during the refining of crude oil and the extraction of natural gas. When cooled or pressurized, these gases turn into a liquid, making them easier to store and transport. Flüssiggas is commonly used as a fuel for heating, cooking, and vehicles. It is popular in areas without natural gas pipelines. Additionally, it can be used in industrial applications and as a feedstock for producing chemicals. Its versatility and efficiency make it a valuable energy source.
