However, this model can be applied for any carbon dioxide delivery system provided a valid method for estimating mass-transfer surface area exists or can be developed. The model provides instantaneous carbon dioxide flux and mass-transfer coefficient values based on real-time pH measurements.- Developed a separate model to look at gas profiles formed inside the membrane lumen during gas transfer. This provides a microscopic perspective into the role of inert gases in reducing carbon dioxide flux and increasing mass-transfer resistance, and steps that can be taken to improve membrane module configuration to mitigate accumulation of inert gases inside the membrane lumen. - Conducted lab-scale abiotic studies to experimentally verify both models in addition to comparing membrane module performance under different modes of operation such as open-end, closed-end, and bleed valve mode. - Published a paper on model estimating carbon dioxide transfer rates in the Journal of Membrane Science. Provisional patent application for membrane carbonation technology was accepted. Working on publishing three additional manuscripts based on this research project. Show less
