Ionic Transport in the Diaphragm of a Chlor-Alkali Cell

“…As shown by Cook (1978) and Nagy (1977) the OH-flux is a direct measure of the anodic current efficiency of chlorine production and therefore K 3 is an important factor in modelling the cell performance. …”

Simplified Flux Equations for Ionic Transport in the Diaphragm of a Chlor-Alkali Cell

“…It is evident from the work of Cook (1978) that the equation proposed by Nagy (1977) works reasonably well for the migration of sodium ions. This is due to the experimentally verified fact (Cook 1978) that the concentration of Na + ions does not vary significantly through the diaphragm.…”

Coupling a Chlor-Alkali Membrane Electrolyzer Cell to a Wind Energy Source: Dynamic Modeling and Simulations

“…•10 R NaCl is the fractional lowering of vapor pressure of the pure water due to dissolved NaCl in the anolyte and it can be expressed by Equation (18) [50]. y out an, NaCl is the molality of NaCl in brine at the outlet of anode, which is given in Equation (19), where ρ out an, (NaCl+H 2 O) is the outlet brine density as expressed in Equation (27).…”

“…Nagy et al [18] developed a steady state mechanistic model for the calculation of material balance parameters, such as concentration of brine and caustic, flow rates and current efficiency losses in diaphragm CA electrolysis. Van Zee et al [19] used a parameter estimation technique with a simple electrochemical model to predict the electrical energy cost for NaOH production.…”
