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.
