Modeling a Direct Contact Heat Recovery Process from Molten Salt Droplets in Various Gases for Thermochemical Hydrogen Production
Authors: , ,
Abstract: The copper-chlorine cycle for hydrogen production is based on thermochemical water decomposition. Heat recovery within the cycle is necessary for high efficiency, and significant heat recovery can be achieved by cooling and solidifying the molten salt exiting the oxygen reactor step of the cycle. Heat can be recovered from the molten salt by breaking the molten stream into smaller dispersed droplets. A predictive model is developed here for direct contact heat recovery process from molten salt using various gases such as nitrogen, helium, argon and air. As CuCl may react with water vapor in the presence of oxygen, inert gases are considered as alternative coolants for the direct contact heat recovery process. It is observed that heat transfer is better for helium than the other gases considered.
