“…The binary parameters for the H 2 O + LA + MIBK system were regressed from experimental data , and the liquid–liquid equilibrium (LLE) model was validated based on the Purac Biochem patent data . The HCl absorption process was also modeled using ELECNRTL with binary parameters from Ref . The extraction columns were sized as tray columns, while absorption and distillation columns were sized in Aspen Plus using the Radfrac model.…”

“…As described in a recent assessment of the thermodynamic properties of the HCl-H 2 O system on the whole composition range (Saravi et al, 2018), the addition of HCl to water, up to about 50 wt%, forms a oneliquid system with H 2 O, H 3 O + and Clas dominant species. At higher HCl concentrations, the content of molecular HCl (aq) increases, which eventually forms a non-miscible phase when concentration reaches 60 to 70 wt% depending on temperature.…”

“…1, as a function of the amount of HCl added to 1 kg of water up to 600 g of HCl (37.5 wt% of HCl), at a total pressure of 1, 3 and 5 bar. The equilibrium curves were calculated using the OLI software and the AQ database (see next section for further details), and validated with the data compiled in the recent article of Saravi et al (Saravi et al, 2018). As illustrated in Fig.…”

“…80%) of V(+5) solutions in the presence of chloride was explained on the basis of activity coefficients. 236 Nevetheless, because of a high vapor pressure of HCl solutions, 237 such mixed electrolytes have not been widely adopted by the VRFB industry. 238 The third major improvement was the switch in VRFBs and other flow batteries from multi-micron to submicron diameter fibers in the porous electrodes.…”
