Abstract

The sulfuric acid decomposition reactor is a key component of the iodine-sulfur thermochemical cycle process. The design of the sulfuric acid decomposition reactor requires excellent corrosion resistance and mechanical strength performance. In this work, a patented reactor on a pilot scale was scaled up to an industrial scale. A plant equipment design for an industrial-scale reactor was performed. Based on an integrated inherent safety design approach, it was determined that the optimal thickness was 110 mm, and the design passed all stress analysis tests. With a minimum targeted hydrogen production rate of 1000 kg/h, the process design yielded a reactor with a diameter of 7 m and a height of 30 m, while silicon carbide was chosen as the construction material. The scaled-up reactor was dynamically simulated in MATLAB. Simulink demonstrated that both the reactor temperature and product flow rates successfully produced a stable response within 1.8 and 4 h of operation, respectively.

硫碘水裂解商业制氢专利卡口反应器的设计、放大和动态模拟
硫酸分解反应器是碘-硫热化学循环过程的关键组成部分。硫酸分解反应器的设计要求具有优异的耐腐蚀性和机械强度性能。在这项工作中,一个中试规模的专利反应器被扩大到工业规模。进行了工业规模反应器的装置设计。基于综合固有安全设计方法,确定了最优厚度为110 mm,设计通过了所有应力分析试验。以最小目标产氢速率为1000 kg/h为目标,工艺设计的反应器直径为7 m,高度为30 m,建筑材料选用碳化硅。在MATLAB中对放大后的反应器进行了动态仿真。Simulink表明,反应器温度和产物流量分别在运行1.8 h和4 h内成功地产生了稳定的响应。

期刊介绍: As the leading archival journal devoted exclusively to chemical kinetics, the International Journal of Chemical Kinetics publishes original research in gas phase, condensed phase, and polymer reaction kinetics, as well as biochemical and surface kinetics. The Journal seeks to be the primary archive for careful experimental measurements of reaction kinetics, in both simple and complex systems. The Journal also presents new developments in applied theoretical kinetics and publishes large kinetic models, and the algorithms and estimates used in these models. These include methods for handling the large reaction networks important in biochemistry, catalysis, and free radical chemistry. In addition, the Journal explores such topics as the quantitative relationships between molecular structure and chemical reactivity, organic/inorganic chemistry and reaction mechanisms, and the reactive chemistry at interfaces.
