Chemical engineering is all about changing raw materials into useful products such as clothes, food and drink, and energy. Chemical engineers focus on processes and products they develop and design processes to create products; either focussing on improving existing processes or creating new ones. This means that they are also concerned with managing resources, protecting the environment and health and safety. Chemical engineers are sometimes called ‘universal engineers’ because it is such a broad discipline they are essentially concerned with transforming one thing into another.
Chemical engineers work in a variety of fields, For instance, they may work at a petroleum refinery to turn crude oil into gasoline, jet fuel, diesel fuel, lubricating oil, solvents and petrochemicals; at a fertilizer plant to produce ammonium nitrate, or at a personal-care product manufacturer to mix dozens of ingredients to produce shampoo or skin lotion.
