Abstract
A detailed steady-state catalytic-reforming unit (CRU) reactor process model is simulated in this work, and for the first time, different compressibility Z factor correlations have been applied using gPROMS software. The CRU has been modeled and simulated with the assumption that the gas phase behaves like an ideal gas. This is assumed for the four reactors in series and for different conditions of hydrogen–hydrocarbon ratio (HHR), operating temperature, and pressure. The results show that the Z factor varies at every point along the height of the reactors depending on reaction operating pressure, temperature, and HHR ratio. It also shows that the magnitude of deviation from ideal gas behaviour can be measured over the reactor height. The Z factor correlation of Mahmoud (J Energy Resour Technol Trans ASME 136:012903, 2014) is found to be suitable for predicting the Z factor distribution in the reactors.
本文对催化重整装置(CRU)反应器的稳态过程模型进行了详细的模拟，并首次使用gPROMS软件对不同的可压缩性Z因子进行了相关性分析。在假设气相为理想气体的情况下，对CRU进行了建模和模拟。这是对四个串联反应器以及不同的氢烃比(HHR)、工作温度和压力条件的假设。结果表明，随着反应操作压力、温度和HHR比的变化，Z因子在反应器高度的每一点上都有变化。它还表明，偏离理想气体行为的大小可以在反应器高度上测量。发现Mahmoud (J Energy Resour technology Trans ASME 136:012903, 2014)的Z因子相关性适合于预测反应堆中的Z因子分布。
