چکیده انگلیسی
A conceptual design of a practical large-scale plant of the thermochemical water splitting the iodine-sulfur (IS) process flowsheet was carried out as a heat application of Japan Atomic Energy Agency's commercial Gas Turbine High Temperature Reactor 300â¯MW for Cogeneration (GTHTR300C) plant design. Innovative techniques proposed by JAEA were applied for improvement of hydrogen production thermal efficiency; depressurized flash concentration of H2SO4 using waste heat from Bunsen reaction, prevention of H2SO4 vaporization from a H2SO4 distillation column by introduction of H2SO4 solution from the 2nd flash bottom, and I2 condensation heat recovery by direct contact heat exchange in an HI distillation column. A simulation of material and heat balance was made using PRO/II, a commercial chemical process simulator. The result demonstrated that hydrogen of about 31,900â¯Nm3/h would be produced by 170â¯MW heat from the GTHTR300C. A process thermal efficiency of 50.2% would be achievable with incorporation of the innovative techniques and the following high performance components expected in future R&D; an electro-electrodialysis cell stack, a reverse osmosis membrane, a HI decomposition reactor incorporated with a H2 permselective membrane, and heat exchangers.
