This research paper introduces a numerical model describing the stripping and drying phase during steam pressure filtration treating water insoluble volatile pore liquids. The model is based on mechanical and thermodynamic equations derived from the theory of steam pressure filtration for aqueous pore liquids and from the steam distillation theory. One main input parameter is the pressure profile determining the state variables of the vapour mixture. This work is first to resolve the pressure profile across a filter cake during stripping and drying based on temperature measurements within the filter cake.

The developed model describes the stripping kinetics and the temperature profile across the filter cake and furthermore reveals a complete removal of the volatile organic compounds from the filter cake. The findings are evaluated by the experimentally determined stripping and drying kinetics. Additionally, exemplary calculations of the temporally and spatially resolved model are shown in order to promote the process understanding.

本研究论文介绍了一个数值模型，描述了蒸汽压滤处理水不溶性挥发性孔隙液体过程中的汽提和干燥阶段。该模型基于从含水孔隙液体的蒸汽压力过滤理论和蒸汽蒸馏理论推导出的机械和热力学方程。一个主要的输入参数是决定蒸汽混合物状态变量的压力分布。这项工作首先基于滤饼内的温度测量来解决汽提和干燥过程中穿过滤饼的压力分布。

开发的模型描述了整个滤饼的汽提动力学和温度分布，此外还揭示了从滤饼中完全去除了挥发性有机化合物。这些发现通过实验确定的汽提和干燥动力学进行评估。此外，还显示了时间和空间解析模型的示例性计算，以促进过程理解。
