| Summary: | 碩士 === 淡江大學 === 化學工程與材料工程學系碩士班 === 99 === The effects on solute mass transfer for a laminar gas absorption process were investigated theoretically and experimentally in this study. A mathematical formulation was developed in a hollow fiber gas-liquid membrane contactor that independently regulates gas and liquid flows. The analytical solution for such a conjugated Graetz problem is obtained by using the separated variable method with an orthogonal expansion technique extended in power series. Physical carbon dioxide absorption in water was studied.
The theoretical predictions show that a higher absorbent flow rate has a positive effect producing better absorption efficiency in the case when the CO2 concentration in gas feed is specified. The absorption efficiency in the countercurrent-flow device is better than that in the concurrent-flow device in the same operating conditions. The experiments of hollow fiber module are set up to confirm the accuracy of the theoretical results.
