Pinch analysis is probably the most widely accepted technology for HENS considering the laws of thermodynamics, which demonstrated excellent efficiency and has been further improved in many different process integration issues correlated to improving sustainability of chemical processes. In this project, we are going to propose the most efficient and optimized HEN, which can result to a huge amount of energy recovery in a big plant for which we have the streams data given in Table 1. ASPEN ENERGY ANALYZER can be utilized to have the best design scenarios, among which you should propose the most optimal design based on your justifications. A detailed technical report including the title page, abstract, table of contents, statement of the problem, your main assumptions, the basis of your selection along with your recommended and justified Grid Diagram, conclusions and references are all needed to be included in your report. Support files for the details of your simulation are necessary to be submitted as welf. Table 1: Problem Data
