ABSTRACT
The experimental modelling of a gas-liquid-liquid
downward flow in a vertical pipe was performed to characterize the
transportation of CO2 for further industrial application of the flow process.
The study involved a multiphase downward flow pipe model integrated with a
high-speed video camera to observe the flow patterns developed from the
experimental proceedings of the flow process. This was achieved by varying the
input flow rates of the CO2 gas phase at high, medium and low set water-cuts
values of the liquid phases. These flow patterns were observed for 0.452 to
32.868m/s range of the calculated superficial velocities of the gas phase. The
homogenous water and kerosene liquid phase was found between 0.452 to 32.868m/s
0.008 to 13.0734m/s at 20, 50, 70 and 90% water-cuts. Subsequently, the
relationship between the area fraction occupied by the gas phase, the
calculated superficial velocities of the gas and the homogenous liquid phases
were utilised to empirically predict the transition criteria of one flow
pattern to another for the developed flow pattern map of the studied flow
system. These findings provide an adequate understanding of the industrial
transportation, carbon capture and underground sequestration of CO2 gas through
a three-phase downward flow in the pipe; to meet the demands of emerging
technologies..
