TL;DR: In this paper, the charge of natural gas adsorption storage systems is studied numerically, with emphasis given to the impact on its dynamics of intraparticle diffusional resistances to mass transport.
Abstract: The charge of natural gas adsorption storage systems is studied numerically, With emphasis given to the impact on its dynamics of intraparticle diffusional resistances to mass transport. Besides adsorption kinetics and thermal effects, the simulation model takes into account both mass transport inside the adsorbent and hydrodynamics of flow through the packed bed. Numerical results are presented for change with methane of a 50 liter cylindrical reservoir, filled with hypothetical adsorbents with diffusional time constants in the range 10−3 s1D/Rp2 ≤ ∞. and with the adsorption equilibrium curve of a commercially available activated carbon with a good adsorptive storage capacity. An attempt is made to assemble the charge histories for different values ofD/Rp2 , in a single cure by using a modilied time scale.

TL;DR: A comparison of the number of floating point operations involved in the different algorithms shows that this approach reduces the operation count for the factorization phase by a factor of about m, with respect to the LINPACK solver.
