Gas absorption into a falling liquid film flowing inside a porous medium is an important heat and mass transfer process for absorption chillers and air-conditioners. The effect of non-absorbable gas on the heat and mass transfer for an absorption process taking place on a falling film flow in a porous medium is studied numerically. The liquid flow is modeled by the Brinkman-Forchhiemer extended Darcy equation. The solutions show that the non-absorbable gas has a strong effect in reducing mass absorption rate. The mass absorption rate increases with increasing solution flow rate, conductivity ratio and absorber pressure, and is optimum with porosity of 0.9 and conductivity ratio of 10.
