Question: Using the film model, estimate the enhancement factor, E, and the resultant flux, JL,CO2 (mol/cm2 s) for a post-combustion capture system using a 5.0 M
Using the film model, estimate the enhancement factor, E, and the resultant flux, JL,CO2 (mol/cm2 s) for a post-combustion capture system using a 5.0 M monoethanolamine solution (~30 wt% MEA). Assume the liquid-phase film transfer coefficient is kL = 0.04 cm/s, and the liquid phase diffusivities of carbon dioxide and MEA are D = 1.8 x 10-5 cm2/s and DB = 0.6 x 10-5 cm2/s respectively. The flue gas enters the separator at 1 atm pressure and has a CO2 mole fraction of 8.5%
