Times Cited Count：0 Percentile：0.01(Engineering, Chemical)In thermochemical IS process for hydrogen production, key issue for realizing high thermal efficiency is to develop an efficient route for the separation of hydrogen iodide from poly-hydroiodic acid. Extractive distillation using phosphoric acid proposed by General Atomics was preliminarily examined by the sequential operation of the extraction and the distillation. It was confirmed that concentrated hydrogen iodide can be separated by the procedure.

JAEA has been conducting the HTTR project from the view to establishing technology base on HTGR and also on the IS process. Based on the test results and know-how obtained through the bench-scale tests, a pilot test plant that can produce hydrogen of about 30 Nm
/hr is being designed. The test plant will be fabricated with industrial materials such as glass coated steel, SiC ceramics etc, and operated under high pressure condition up to 2 MPa. The test plant will consist of a IS process plant and a helium gas (He) circulation facility (He loop). In parallel to the design study, key components of the IS process such as the sulfuric acid (H
SO
) and the sulfur trioxide (SO
) decomposers working under-high temperature corrosive environments have been designed and test-fabricated to confirm their fabricability. Also, other R&D's are under way such as corrosion, processing of HIx solutions. This paper describes present status of these activities.

High efficiency flowsheet for thermochemical hydrogen production IS (Iodine-Sulfur) process is investigating. In order to establish the reference flowsheet that is concidering the recent experimental data and engineering investigation, steady state process simulation was done using process simulation code PRO/2 and thermochemical model/database(developed by OLI Systems, Inc.) which was extended for IS process. The results of parameter analyses and established reference flowsheet are reported.

The Japan Atomic Energy Agency (JAEA) has been conducting the HTTR (High-Temperature Engineering Test Reactor) project from the view to establishing technology base on HTGR and also on the IS process. In JAEA, continuous hydrogen production was demonstrated with the hydrogen production rate of about 30 NL/hr for one week using a bench-scale test apparatus made of glass. Based on the test results and know-how obtained through the bench-scale tests, a pilot test plant that can produce hydrogen of about 30 Nm/hr is being designed. The test plant will be fabricated with industrial materials such as glass coated steel, SiC ceramics etc, and operated under high pressure condition up to 2 MPa. In parallel to the design study, key components of the IS process have been designed and test-fabricated to confirm their fabricability. Also, other R&D's are under way such as steady state simulation of pilot system, corrosion resistant seal and piping technology. This paper describes present status of these activities.
