CBM Reservoir - Critical Desorption Pressure - Gas starts desorbing and diffusing in coal-matrix. Which of the following approaches better describe the in-situ desorption of methane gas within the low-porous low-permeable coal-matrix ??
Non-Equilibrium Sorption OR Sorption Kinetics??
Is it feasible to quantify the fraction of micro-pores, meso-pores and macro-pores/fractures associated with a typical coal-matrix?
And if we have such a complex distribution of mixed pore sizes within the coal-matrix, how far using Non-LInear Equlibrium Langmuir Sorption Isotherm is justified?
what is understood under "non-equilibrium sorption" as contrasted with "sorption kinetics"? "Non-equilibrium" presumes either sorption or desorption kinetics. or, is that about exit from a metastable state?
