Modeling of Carbon Dioxide (C02) - Natural Gas Separation Using Membrane

Currently, the existing methodology for carbon dioxide (CO2) removal is not sufficient to
remove high concentration of CO2in our natural gas supply. At the moment, the use of
membrane separators is gaining popularity as years passed by and is slowly replacing
absorption system to remove high CO2 content. By using membrane gas separation units,
they are smaller than other types of plants as compared to amine stripping plants.
Therefore, have relatively small footprints as it is important in environments such as
offshore gas-processing platforms.
In this study, 6FDA-TADPO polypyrrolone, which is a dense polymeric organic
membrane model, will be analyzed. By collaborating dual-mode sorption model together
with bulk flux contribution, the study of selectivity and permeability of carbon dioxide
and methane in natural gas towards the membrane is done using Matrix Laboratory
(MATLAB) where the behavior of the gases at certain pressure and composition is
determined. The results obtained from the model are then validated with experimental
data.
