TL;DR: In this paper, Nernst-Planck derived relationships were used to simulate the electrodialytic recovery of a strong electrolyte, namely sodium chloride, in a five-step experimental procedure consisting of zero-current leaching, osmosis, and dialysis, electro-osmosis, desalination, current voltage and validation tests.

TL;DR: In this article, a level set approach is applied for simulating the interphase mass transfer of single drops in immiscible liquid with resistance in both phases, and different spatial discretization schemes including the fifth-order WENO, second-order ENO and power-law schemes are tested for the solution of mass transfer to or from single drops.

TL;DR: In this article, the authors evaluated the rates of mass transfer of the individual components of four synthetic dense non-aqueous phase liquid (DNAPL) mixtures into the aqueous phase.
Abstract: Parameters governing the rates of mass transfer of the individual components of four synthetic dense non-aqueous phase liquid (DNAPL) mixtures into the aqueous phase were evaluated. The DNAPL mixtures, composed of toluene and eight polynuclear aromatic hydrocarbons (PAHs), were designed to serve as models for coal tars and creosotes. The reactor employed provided a relatively stable interface between internally mixed but segregated aqueous and DNAPL phases. Two parameters, the aqueous phase concentration at equilibrium and the overall film mass transfer coefficient, were quantified by simulating aqueous concentration profiles with a mass-transfer-limited rate model using a statistical parameter search and data fitting routine. DNAPL phase activity coefficient values for the various compounds derived from equilibrium aqueous phase concentrations were typically within a factor of 2 of Raoult's law prediction of unity; refinement of fugacity ratio estimates for the solid PAHs brought the values even closer t...
