*2.6. Step 6: Discuss and Analyse the Results*

To select the HP suitable for each of the possible processes, the solutions obtained during Steps 1–5, provide engineers with sufficient information and understanding of why the proposed measures are appropriate and efficient. The evaluation is performed by the combined use of Pinch Analysis and Petro-SIM to simulate and optimise the HPs. The actions include constructing the GCC of the process and combining it with the plots of the considered HPs. The combined plots are then used for explaining the solutions and relating them to the process specifications—i.e., the temperatures and heating/cooling duties of the main process, plus the HP properties—i.e., working fluid and operating pressures.
