Chemical Engineering involves the design and maintenance of chemical plants and the development of chemical processes for converting raw materials or chemicals into
valuable forms including those to remove chemicals from waste materials, to enable large-scale manufacture.
It combines knowledge of Chemistry and Engineering for the production of chemicals and related by-products. This branch of engineering is a varied field, covering areas from biotechnology and nanotechnology to mineral processing.
It covers various fields of chemical technology in mineral based industries, petrochemical plants, pharmaceuticals, synthetic fibres, petroleum refining plants etc.
