| Summary: | Membrane contactor is a technology that combines the principle of separation
using a membrane and gas-liquid absorption. The membrane contactor process has
various advantages including having a higher contact area compared to
conventional absorption. Each module type has different efficiency on membrane
contactor operation. Therefore, module configuration development is one of the
keys to increase the separation process efficiency.
This type of research is a literature review. The data used in this research is
secondary data from scientific articles or journals. The procedure in this study
includes collecting and organizing data to be reviewed then data synthesis. The
main objectives of this literature study are to compare the types of membrane
contactor modules, to determine the effect of flow patterns on membrane contactors
for component fluks, to determine the effect of module design factors, applications,
challenges and prospects for the development of membrane contactors in the future.
Based on the membrane module type, the hollow fiber membrane is more efficient
than other module types because it has higher interface area and lower pressure
drop during process operation. Based on the flow pattern, the crossflow module
has the best CO2 absorption approximately at 80%, where the solution is in the
shell and the gas is in the lumen. For the design factor, low density modules produce
higher absorption fluks than high density modules, and the height of the membrane
layer affects the CO2 concentration obtained. The development of the membrane
contactor configuration has been used in various applications such as the capture
of acid gas components from the gas mixture, gas humidity control, oxygenation,
deoxygenation, ozonation processes, and refrigeration systems. This study is
expected to be able to provide scientific benefits regarding the development of a
membrane contactor module in the gas-liquid separation process. |
