This work is focused on the analysis of some relevant aspects involved in the solid-vapor-liquid (SVL) equilibrium modeling at high pressure: the parameter estimation of cubic equations of state commonly used in the literature and the application of a stability test to accomplish the calculations. Conversely to the current literature, it is shown in this work that the proposed scheme for phase equilibrium...
This work aimed at modeling chromium biosorption using the biomass of seaweed Sargassum sp. in a fixed-bed column. The mathematical model used was obtained from the mass balance of the component in the liquid phase and in the biosorbent material. The effects of both axial dispersion in the column and the resistance to mass transfer in the solid were considered for the solution of the partial differential...
