In this dissertation, the use of pressure exchangers as an energy recovery device was highlighted as a solution to the global energy shortage issue that we are currently facing. As such, different designs of pressure exchangers with respect to their intended applications were discussed. Apart from that, one of the main obstacles preventing this device from resolving the world’s energy crisis was also addressed through a detailed mathematical modelling. In the first phase of the project, the basic components and working principles of a pressure exchanger were introduced through conceptual explanation. Then, the major features of a pressure exchanger were studied to determine their advantages and barriers in the pressure transmission process. Based on these features, several criteria were identified to classify the various existing pressure exchanger designs. The classifications were made based on the type or phases of the working fluids, the operating principles used in a pressure exchanger, the use of a separation mechanism and other additional features that can be incorporated into a pressure exchanger. The research methods that were used include studying the basic structure and working principle of a pressure exchanger, conducting a theoretical analysis of different designs while determining the advantages and disadvantages of each design, classification of each design based on certain criteria, identifying the various industrial applications of the device and studying its economical feasibility as compared to a conventional method. The second phase of the project involves performing a detailed mathematical modelling to represent the dynamic flow of fluids in a basic rotary pressure exchanger design. The model can also be used to determine the overall pressure transfer efficiency of the device. Finally, opportunities for further study on this subject were identified in which this basic pressure exchanger model can be further developed to facilitate a specific industrial application.
