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.

可压缩系数对石脑油催化重整反应器流体力学的影响

在这项工作中模拟了详细的稳态催化重整单元（CRU）反应器过程模型，并且首次使用gPROMS软件应用了不同的可压缩性Z因子相关性。在假设气相行为像理想气体的假设下对CRU进行了建模和仿真。对于串联的四个反应器，以及不同的氢烃比（HHR），工作温度和压力条件，都采用了这种方法。结果表明，Z因子沿反应器高度的每个点都会变化，具体取决于反应操作压力，温度和HHR比。它还表明，可以在反应器高度上测量与理想气体行为的偏离量。该ž发现Mahmoud因子相关性（J Energy Resour Technol Trans ASME 136：012903，2014）适合预测反应堆中的Z因子分布。
