C3+ refers to a mixture or fraction of hydrocarbons derived from crude oil or natural gas that contains hydrocarbon molecules with three or more carbon atoms. It includes a range of hydrocarbons, such as propane, propylene, butanes, butylenes, and higher hydrocarbons. C3+ fractions are commonly used as feedstocks in various industrial processes, such as petrochemical production, fuel blending, and as heating fuels. The specific composition and applications of C3+ fractions can vary depending on the source and refining processes involved. For example, propylene, a C3 hydrocarbon, is widely used in the production of plastics, fibers, and other chemical products.
