ABSTRACT
The design engineer must consider appropriate energy conservation/integration schemes that are designed to: The energy balances performed for the plant items provide the initial key to identifying areas of high energy availability or demand. The areas immediately obvious for consideration of energy utilisation are the feed preheating section of the plant, and the distillation section by attempting to optimise condenser and reboiler duties on various columns. Energy conservation in the design of complete processes may be achieved in four ways: Items to represent short-term and medium-term energy conservation measures. Process control and the associated instrumentation were discussed briefly in relation to the process selection. An overall view of the plant and its objectives should help to focus the process control strategy on particularly sensitive areas. Safety checklists can provide a useful guide to the main actions to be considered during the process design stage.
