Analysis of Solar Thermochemical Water-Splitting Cycles for Hydrogen Production
Approach • Review all published papers, reports, patents, etc. in the past 25+ years that relate to thermochemical water-splitting cycles, in general, and solar driven cycles, in particular. • Use FactSageTM program to perform chemical equilibrium calculations. • Employ HYSYS/ASPEN Plus chemical process simulation (CPS) program for developing process flowsheet, process analyses and optimization...
متن کاملMaterials Development for Improved Efficiency of Hydrogen Production by Steam Electrolysis and Thermochemical-Electrochemical Processes
We are investigating two processes as potential sources of hydrogen for the “hydrogen economy”. One of these hydrogen production processes is water electrolysis at high temperatures using heat from a nuclear reactor, known as high temperature steam electrolysis (HTSE). The feasibility of this process is currently being demonstrated at Idaho National Laboratory using solid oxide fuel cell design...
متن کاملThe Single Absorption – Scrubbing Sulfuric Acid Process
The AE&C single absorption–scrubbing process has long been an alternate to double absorption for the production of sulfuric acid. In recent years regulatory pressure to reduce SO2 emissions from sulfuric acid plants to 1.0-1.25 pounds of SO2 per ton of acid produced (to about 120 PPM) or less coupled with the increased value of energy has enhanced the desirability of the single absorption–scrub...
متن کاملEffect of Water Transport on the Production of Hydrogen and Sulfuric Acid in a PEM Electrolyzer
The thermochemical cycle involving the interconversion between sulfur dioxide and sulfuric acid is a promising method for efficient, large-scale production of hydrogen. A key step in the process is the oxidation of sulfur dioxide to sulfuric acid in an electrolyzer. Gaseous SO2 fed to a proton exchange membrane PEM electrolyzer was previously investigated and was shown to be a promising system ...
متن کاملOptimization studies in sulfuric acid production
Current legislation imposes tighter restrictions to reduce the impact of process industry on environment. This work presents the dynamic simulation and optimization results for an existing sulfuric acid plant. Operational problems may occur when the process is disturbed due to production rate changes or catalyst deactivation, the non-linear response of the plant leading to sustained oscillation...
