Entitled "Natural Gas Phase Behaviour in Pipeline", this project ultimately aims to enable natural gas phase simulation using FLUENT to present a real time graphical interpretation of the liquid, gas and component fractions. The studies of these phenomena are important in the natural gas dehydration processes and its flow through pipeline because the existence of liquid in the pipeline can bring detrimental effects to operations. Water content in the gas system could cause large pressure drop and corrosions that will be enhanced by the presence of H2S and CO2 typically associated in sour gas. This research is the beginning phase of the development of an emerging type of gas separation technology. Currently, the computation of gas phase behaviour into simulator for this purpose is scarce and not easily found in FLUENT environment. Hence, the scope of research covers the investigation of suitable correlations/equations and subsequently computed, and simulated using the model. Study of operating condition to achieve desired separation is also done once the program has been developed and verified with other commercial software and literatures. These correlations must be able to estimate the liquid and gas fraction in the system, components liquid and gas composition, and the water content in the gas system to certain acceptable degree of accuracy and defined limitations. The research started with literature review to investigate suitable correlations, followed by development using C++
