Which fraction of crude oil is used as bottled gas?

Bottled gas, commonly referred to as liquefied petroleum gas (LPG), primarily consists of propane and butane, which are light hydrocarbons. These hydrocarbons are typically obtained from the refining process of crude oil, specifically from the refinery gases fraction. This fraction is made up of the lighter components of crude oil and is collected during the distillation process. Unlike gasoline, diesel, and bitumen, which are heavier and used for different purposes (like fuels for vehicles or construction materials), the refinery gases fraction is specifically processed and stored for use as bottled gas. The properties of these light gases make them suitable for household use and fuel for cooking, heating, and portable energy solutions.
