Chemical Engineering is a branch of engineering that applies principles of chemistry, physics, mathematics, and biology to the design, optimization, and operation of processes for the production and use of chemicals, materials, and energy. It involves the development and design of equipment and processes for large-scale manufacturing, ensuring safety, sustainability, and economic feasibility. Chemical engineers work in various industries, including petrochemicals, pharmaceuticals, food production, and environmental engineering, focusing on transforming raw materials into valuable products while minimizing environmental impact.
