Chemical engineers design, construct and operate process plants (fractionating columns pictured)Chemical engineering is a branch of engineering that uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, transform, and transport chemicals, materials, and energy. A chemical engineer designs large-scale processes that convert chemicals, raw materials, living cells, microorganisms, and energy into useful forms and products.Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, control engineering, chemical reaction engineering, biological engineering, construction specification, and operating instructions. Chemical engineering degree is directly linked with all the majors of various engineering disciplines.
