Chemical engineers are concerned with the ways in which raw materials are changed into useful and commercial products. This involves the research of different materials and their properties also the way to design and develop equipment.
These skills are combined to extract raw materials which can then be refined and manufactured to produce such things as food, petrol, plastics, paints, paper, minerals and metals. Often these processes are carried out at large scale process plants – the safety operation of these plants are also part of a chemical engineers work.
Extracting raw materials without harming the environment is a major part of work for a chemical engineers. They are also involved in the production of pharmaceutical product..
