Chemical engineering is diverse. Students may be involved in water purification, food production and processing, or developing products such as cosmetics or soap. Students will design and develop ways in which raw materials, such as minerals and oil, are converted into useful products including composites, petrol, plastics and paper. As a chemical engineer, graduates can work in diverse fields including petroleum production and refining, mineral processing, water purification, wastewater treatment, oil production, research and development, process design and consulting, and environmental management and pollution control.
