Theoretical studies on carbon dioxide removal from a gas stream in hollow fiber membrane contactors

Abstract : This paper presents theoretical studies and modeling investigations on the reactive absorption of carbon dioxide in alkanolamine solutions, specially the monoethanolamine, in a hollow fiber membrane contactor device. The absorption mechanism was built based on mass transport conservation laws in all three regions involved in the process, i.e. the gas phase, the membrane barrier and the liquid region. The gas is flown in the fiber bore in which the velocity is assumed to obey a fully developed laminar flow, and the liquid solution is circulated counter-currently to the gas flow in the shell side where the velocity is characterized by the Happel's free surface model. The rigorous model consisting of a set of highly non-linear partial differential equations is rewritten in dimensionless form and numerically solved. The outlet gas and liquid concentrations are parametrically simulated with the gas and liquid flow rates (Graetz numbers) as well as inlet fresh solvent concentrations.
