Properties and phase behavior of CO2-rich fluidsProperties and phase behavior of CO2-rich fluidsΙδιότητες και φυσικοχημική συμπεριφορά ρευστών πλούσιων σε Διοξείδιο του Άνθρακα Μεταπτυχιακή Διατριβή Master Thesis 2021-10-222021enThe main goal of this master thesis project is to compare two PVT simulation software packages. The simulator software programs under study are the KBC’s (now acquired by Yokogawa Company) Multiflash and HydraFLASH from HydraFact Ltd. Both simulators are supposed to make same predictions and compared to existing experimental data. However, it is shown that performance of them might exhibit significant differences, even though same equations of state were applied for calculations in both software. Introduction chapter provides brief description of Carbon Capture and Storage process, as well as overview of properties of carbon dioxide. In Chapter 2, popular equations of states employed for calculations will be presented, as well as short description of software packages used for this project. In chapter 3 density will be discussed, which is one of the most important thermophysical property for CCS processes. Both multi-component and binary mixtures will be examined. In chapter 4, speed of sound property will be discussed. Chapter 5 presents solubility of CO2 in water and salt aqueous phase, and lastly Chapter 6, provides information about hydrate dissociation data between two software and experimental data. In the conclusions part our thoughts regarding both software packages will be finalized and therefore final judgement will be made. By finalizing this study, a more solid judgement on performance of these two software programs on the different simulations has been built.In this study, comparison of all important calculations between two commercial simulators has been made and discussed. Consideration all results, mostly both programs are producing quite similar results. http://creativecommons.org/licenses/by/4.0/Technical University of Crete::School of Mineral Resources EngineeringNedeljkovic_Milan_MSc_2021.pdfChania [Greece]Library of TUC2021-10-22application/pdf5.1 MBfree Nedeljkovic Milan Nedeljkovic Milan Pasadakis Nikos Πασαδακης Νικος Marinakis Dimitrios Μαρινακης Δημητριος Tohidi, Bahman Πολυτεχνείο Κρήτης Technical University of Crete Phase behavior and properties CO2-rich fluids
