The main difference between a natural gas and a natural gas liquid is that natural gas is composed of many different molecules, while natural gas liquids are composed of a single type of molecule. Natural gas is usually composed of methane (CH4), ethane (C2H6), propane (C3H8) and butane (C4H10). Natural gas liquids are made up of ethane, propane, butane and other hydrocarbon gases like pentane and hexane.
