A continuous electrochemical process for bromine production from brine solutions was developed based on bromide oxidation and flow-through porous electrode technology. The bromide oxidation kinetics in a three-dimensional porous graphite electrode was determined using a small test flow cell. The data were analysed and combined into a process model to evaluate the electrode performance under many different operating conditions. Bromide conversions against cell sizes for various brine throughputs were calculated using model equations and verified by experimental data collected from a 45 cm long pilot cell.
