Wastewater effluent from alkaloid processing plants has the potential adverse environmental influences. Mathematical modelling and simulations were carried out using computational fluid dynamics of mass and momentum transfer in a hollow fibre membrane extractor. Conservation equations were derived for tyramine extraction in the membrane extractor and solved based on the finite element method. Model findings based on the computational fluid dynamics validated well with the experimental data. The results showed that increase in organic-phase flow rate, as well as the fibre length and its porosity, has a positive impact on the performance of the extractor, whereas the enhancement of aqueous-phase flow rate led to the reduction of tyramine extraction.
来自生物碱加工厂的废水可能会对环境产生不利影响。使用中空纤维膜萃取器中的质量和动量传递的计算流体动力学对其进行了数学建模和模拟。推导了在膜萃取器中提取酪胺的守恒方程，并基于有限元法对其进行了解决。基于计算流体动力学的模型研究结果与实验数据吻合良好。结果表明，有机相流量的增加，以及纤维长度和孔隙率的增加，对萃取器的性能有积极的影响，而水相流量的增加则导致酪胺的提取减少。
