Chemical Engineering aims to transform raw materials and chemicals into useful products. It uses principles from engineering and science disciplines like mathematics, physics, chemistry and more. The goal is applying scientific knowledge to industrial processes. Chemical engineers develop and design equipment, processes and plants for large-scale production.In the 21st century, chemical engineering underwent a significant transformation, incorporating advancements brought by the new millennium. By the 2000s, it was redefined as the engineering discipline focused on designing and implementing processes that modify the chemistry, energy levels, or physical properties of materials.
