Development of efficient HI processing scheme is important for attaining high thermal efficiency of hydrogen production by IS process. We are studying an application of electro-electrodialysis to pre-concentrate the HIx solution before distillation, which is supplied from the Bunsen reaction section. So far, feasibility of the pre-concentration was experimentally verified and also, by flowsheet analysis, the importance was clarified of improving the performance of membrane and electrode catalyst.
