本研究的主要目的是对克劳斯工艺进行改进，使其通过硫化氢分解生产超纯氢。克劳斯工艺中的加热炉和催化反应器配备了盘管和氢渗透选择性膜管。在所提出的结构中，氢气在盘管炉中产生，并在膜反应器中与气流分离。根据稳态条件下的质量和能量平衡方程，对常规工艺和改进工艺进行了建模。为了验证所建立的模型和考虑的假设的准确性，将常规工艺的模拟结果与现有的工厂数据进行了比较。此外，为了最大限度地提高硫磺回收率和制氢效率，利用遗传算法在考虑操作和环境约束的情况下，计算出了该工艺的最优操作条件。在模拟结果的基础上，对常规加热炉和改进型加热炉的产氢速率进行了预测。
The main goal of this research is modification of the Claus process to produce ultrapure hydrogen through hydrogen sulfide decomposition. The furnace and catalytic reactors in the Claus process are equipped with coil and hydrogen perm-selective membrane tubes. In the proposed structure, hydrogen is produced in the coil furnace and separated from gas stream in the membrane reactors. The conventional and proposed processes are modeled on the basis of the mass and energy balance equations at steady state condition. To prove the accuracy of developed model and considered assumptions, the simulation results of conventional process are compared with the available plant data. In addition, to achieve maximum sulfur recovery and hydrogen production, the optimal operating condition of the proposed process is calculated by considering operational and environmental constraints by the Genetic algorithm. On the basis of the simulation results, the rate of hydrogen production in the conventional and proposed furnaces ar...
