In this paper, we perform detailed energy and exergy analyses of a four-step integrated copper–chlorine cycle for hydrogen production. In this regard, we consider the incorporation of the flash vaporization technique as a novel approach to the anolyte separation process in the cycle. The flash vaporization process is most commonly used commercially for the desalination of seawater. However, there are no studies in the literature that consider the application of this technique for a themochemical process in general and for the anolyte separation purposes in a copper–chlorine cycle in particular. The rationale for the need for an alternate anolyte separation technique is based on our previously published results considering the energy and exergy analyses of the Cu–Cl cycle in the Clean Energy Research Laboratory (CERL) at the Ontario Tech University, where it is reported that the current anolyte separation approach is relatively energy-intensive. The purpose of this modification is to perform the partial separation of the oxidized anolyte at a reduced temperature by realizing the separation process under vacuum conditions. In this regard, the results of the energy and exergy analyses of the integrated cycle conceptually modified with flash vaporization process are compared to those of the original integrated cycle in terms of the total exergy destruction, overall heat input and rejection rates, overall energy and exergy efficiencies, and heat input and exergy destruction of the anolyte separation step. According to the energy and exergy analyses, the modified cycle results in relatively lower exergy destruction (with 196.6 MW) compared to the original cycle (with 209.2 MW) and relatively higher overall energy (7.2% compared to 6.6%) and exergy (11% compared to 10.2%) efficiencies.
