"Think In Other Terms"

The United Kingdom Institution of Chemical Engineers (IChemE) defines chemical engineering as: “the branch of engineering which is concerned with processes in which materials undergo a required change in composition, energy content or physical state; with the means of processing; with the resulting products and with their application to useful ends”In other words chemical engineers take chemistry out of the laboratory and into the factory and the world around us.Chemical engineering deals with industrial processes in which raw materials are converted into useful products. This means developing, designing and engineering both the complete process and equipment used in the production.The chemical engineer must choose the proper raw materials, operate the plant efficiently, safely and economically and ensure that the products meet the requirements set by industry. All over the world , chemical engineers are helping to advance and sustain our modern society. They manage natural resources, protect the environment and create and develop the processes that make the products we all depend on – pharmaceuticals, artificial fibres, plastics, food and drink, fuels and toiletries for example Thus chemical engineers draw on the chemical, physical and biological sciences and on mathematics to provide a systems approach to the understanding of the changes which take place in processes, from the molecular to the global scale, and to establish methods which can be employed to achieve required changes in composition, energy content, structure or physical state. Two of the most important industries in Zimbabwe are agriculture and mining. Agriculture provides people with food. Cash crops such as tobacco are major foreign currency earner. To produce high yields farmers need fertilizers and pesticides, which are manufactured in traditional plants using chemical engineering principles. The waste products from these industries are also treated by chemical engineers in the effluent treatment and recycling industries.
