Chemical and metallurgical engineers usually find themselves as engineers for certain process industries. sketch a labelled process flow chart for any product/metal production. (15) note for question 1a): • the flow chart should be your own work and not a copy and paste diagram. any product process is acceptable except the one for pulp and paper industry process flow chart (can be a product process or manufacturing) • start from raw material to the final product (assure that the flow structure is sequential) • include input resources, conversion steps, output and recycle stream (could be waste streams as well) where required, include electricity and other energy flows and also indicate where it is not required b) explain the importance of the ability to identify and draw/sketching process flow charts (2) c) describe the significance of material and energy balances to process engineering
