Coking
Coking is an important industrial process that turns heavy oil materials into more valuable petroleum products. Think of it like a cooking process, but for oil refineries. It takes thick, heavy oil that's less useful and transforms it into lighter products like gasoline and diesel fuel, plus a solid material called coke. This coke can be used in other industries, such as making steel or aluminum. When you see this term in resumes, it usually refers to experience with either delayed coking or fluid coking, which are the two main methods refineries use. It's a critical skill in oil refineries and petrochemical plants.
