Process Simulation of Iodine-Sulfur Thermochemical Hydrogen Production Process

Abstract

Cycle simulation of the Iodine-Sulfur thermochemical hydrogen production process was conducted for the establishment of the closed cycle continuous operation method. After the confirmation of validity of simulation model for each unit of the IS process, the effect of disturbance for the process on the continuous operation was investigated by changing flow rate of circulating substances. It was found that there were two cases of disturbance. One is that the disturbance amplifies the fluctuation in the process. Another is that the disturbance offsets the fluctuation. The operating condition of the latter case was found to close on the new steady state.
