A process engineer develops and optimises industrial processes to make the huge range of products on which modern society depends. This includes oil and gas, water, pharmaceuticals, food and beverages, paper and sugar. Process engineers have an understanding of the chemistry and physics required for these processes, the related equipment and how to integrate many individual operations into an integrated factory. Process engineers typically work in either large consulting firms in head offices where the design occurs, or onsite in factories. In Australia, process engineering is the destination career for chemical engineering graduates.
