The term "gas liquids" refers to a group of hydrocarbon-based gases that are in a liquid state at room temperature. These gases have low vapor pressures and can be used as fuels, solvents or feedstock for the production of other chemicals. Some common examples include propane, butane, isobutene and pentanes. Gas liquids are often extracted from natural gas during processing and can also be produced through refining processes such as cracking. They have a wide range of industrial applications including heating, cooking, refrigeration, and as feedstock for the production of chemicals like plastics or fertilizers.
