Chemical engineering is a branch of engineering that combines principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, design, transport, and transform energy and materials. It involves the design, optimization, and operation of processes that convert raw materials into valuable products, such as fuels, pharmaceuticals, chemicals, food, and materials. Students in chemical engineering study subjects like thermodynamics, fluid mechanics, material science, and reaction engineering, while also learning about process control, environmental sustainability, and safety. The course emphasizes problem-solving and analytical skills, preparing graduates to work in industries like energy, manufacturing, biotechnology, and environmental protection, where they design and improve processes that impact everyday life.
