Summary:Last time I introduced a hypothetical plant consisting of 7 processes producing 6 different products. Without doubt this process sequence will also require energy to operate. Some, or all, of the plant will require the provision of various external services too. For purposes of simplification and illustration, I've ignored added complexities such as process losses, waste disposal and internal scrap recycling flows. With a hypothetical plant now established, we can start to think about energy utilisation modelling. An understanding of what each process is making, when and how it is making it, is key to evaluating the consumption of all the materials the plant needs to achieve its purpose. Clearly the superimposition of the consumptions of multiple processes, each with varying time-bases, is not a trivial exercise. However, it's one we can readily address with energy utilisation modelling. Energy utilisation modelling is an integral component of Innoval's process cost modelling approach which we apply to many process and plant scenarios.
