The chemical manufacturing processes have involved from modest to complex production of chemicals converting raw materials such as fossil fuels, water, minerals, metals, and others to become thousands of products central to our everyday modern living. Chemical and process engineering deals with the development, design, operation, and management of converting these raw materials safely and cost- effectively. It is founded on the principles of chemistry, physics, and mathematics. The laws of physical chemistry and physics govern the practicability and efficiency of chemical engineering operations, whilst mathematics aids the essential tool in optimization and modelling.
