Abstract

This project aims topredict carbon dioxide composition in natural gas system using commercial fluid dynamics simulators (i.e FLUENT software). Currently, there is no fluid dynamics software that is able to capture phase change behavior of mixture components. Hence, this project involves incorporation of thermodynamics properties into FLUENT. This can be done by implementing coding using Peng Robinson model into FLUENT. Peng Robinson model is used because it has better behavior at critical point and thus, suitable to be used for vapor system. In this project, only a binary mixture of vapor phase is used for simplicity purposes. The scope of study also covers the operating condition to achieve desired separation using cryogenic process. The research started with literature review to investigate suitable model to be used, followed by development using C++ programming. The completed program is verified with HYSYS before further simulations are done. Once it is validated, simulation using a simple pipe is performed and results are validated with HYSYS again. Results obtained are almost as accurate as HYSYS and hence, this shows that thermodynamics properties using Peng Robinson model is able to be applied into FLUENT. This project has successfully produce computational code for vapor phase behavior studies to be implemented into FLUENT. This model in FLUENT is able to capture the phase change behavior and hence, enables the selection of the best design for intended separation.
