采用泽尼斯法对混合油进行脱酸，可以精炼高酸价油、降低中性油皂化机率、减少皂脚夹油、降低生产成本等。在混合油泽尼斯法脱酸最佳工艺条件下利用 Fluent 软件，并采用 VOF 模型对泽尼斯塔内部混合油流动进行 CFD 数值模拟，得到泽尼斯塔内部流场的混合油相分布、速度矢量分布、绝对速度分布和动压力分布。通过分析模拟结果，可以得到将混合油通过单孔泵入泽尼斯塔时油滴的动力学特性，为泽尼斯塔的优化和油滴分布器的设计提供了新的研究方法和必要的理论依据。另外，通过建立模型进行数值模拟，得到了准确可靠的液—液两相流数据分布。

Miscella was deacidified by zenith method,which has many advantages such as refining higher acid value oil,reducing the chances of neutral oil being saponified,reducing residual oil in soapstock and reducing production cost.Under the optimal deacidifying process conditions,the flow of miscella in-side of zenith tower was simulated by Fluent software with VOF model.The phase distribution,velocity vector distribution,absolute velocity distribution and dynamic pressure distribution of miscella of the flow field inner the tower was obtained.The result showed that the dynamic characteristics of the droplet were obtained by pumping miscella into the zenith tower through single -nozzle,which provided a new re-search method and the necessary theoretical basis for the optimization of zenith tower and the design of the oil droplet distributor.In addition,by establishing numerical simulation method,the accurate and relia-ble results of liquid-liquid two-phase flow were obtained.
