Abstract

Il is widely agreed that the most energy consuming part of the S-l thermochemical cycle
for hydrogen production is represented by separation processes, especially for the HI
decomposition section. The design of these processes and consequently the assessment
of the real potential of the S-l cycle depends on the understanding of thermodynamic
equilibrium and models construction of the ternary system HI-H20-l2. In this paper, a
new thermodynamic model for the electrolyte system HI-l2-H2O is proposed and
validated against vapour-liquid (V-L) equilibrium data at atmospheric pressure. The
proposed model provides a reliable description of V-L equilibrium of the ternary system
of interest.
