Propane, a colorless and odorless gas, is a highly versatile and widely used chemical compound. Its chemical formula, C₃H₈, indicates that a propane molecule consists of three carbon atoms and eight hydrogen atoms. It’s classified as a hydrocarbon and belongs to the class of compounds known as alkanes.

Origins and Extraction

Propane is primarily a byproduct of two sources: natural gas processing and crude oil refining. The extraction of propane occurs during the processing of natural gas and the refining of petroleum, where it is separated from other hydrocarbons. It’s usually found in combination with other hydrocarbons such as methane and butane.

• Natural Gas Processing: Propane is separated from natural gas in a processing plant where raw natural gas is treated. It involves removing heavier hydrocarbons from the natural gas to meet the specifications for marketable natural gas.
• Crude Oil Refining: It also comes as a byproduct of petroleum refining where crude oil is processed into various fuel products like gasoline, diesel, and jet fuel. The process of distillation separates the crude oil into different components based on their boiling points.

Physical and Chemical Properties
