2. this question is aimed at exposing you to membrane separations. to answer, see Ch. 7, Sec. 2 of "Introduction to Carbon Capture and Sequestration" by Smit, Reimer, Oldenberg, and Bourg, available for free as an e-book through the OSU library at library . oregonstate. edu. generally, the permeability of a gas species through a membrane is determined by both its solubility (a thermodynamic property) and diffusion (a kinetic property) in the membrane. (a) what is the difference between "flux", "permeability", and "permeance" of a gas species through a membrane? write the definition of each and the units associated with them (the units explain the meaning, too). (b) explain the three different mechanisms by which a membrane can exhibit a different permeability for two gases (e.g., CH4 vs. CO2 ), depicted in the figure below. while (a) and (b) are extreme cases, (c) is the more general case
