Experimental characterization of engine oil filter materials and determination of permeability

随着燃料的运输，它会被管垢和水中的无机颗粒污染， 碳氢化合物凝析油，它降低了石油的质量。因此，悬浮液/固体的过滤 来自不同类型机油(燃料、润滑油和液压系统油)的污染物在许多情况下是一个重要步骤 工业。过滤固体颗粒或液滴的最有效方法之一是使用过滤介质。 目前，所有汽车发动机，无论是汽油还是柴油，都配有过滤装置来改善机油 清洁，从而延长发动机的使用寿命，导致机油滤清器的年总销量约为4.25亿 这只发生在美国。在本研究中，一种新的专有设计的同心聚结器和分离器过滤器集于一体 单个单元将通过改变不同的运行条件进行测试。这一设计预计会有更低的 压力降，与现有设计相比将更加紧凑。此外，基于流程模型 关于多孔介质中的对流扩散方程将被用来确定渗透率作为 膜材料的厚度、油性和操作变量，并将使用 实验数据。

As fuel is transported, it gets contaminated with inorganic particles from pipe scales and water and hydrocarbon condensates, which degrade the quality of oil. As a result, filtration of suspended liquid/solid contaminants from different type of oils (fuel, lubricant and hydraulic system oil) is an important step in many industries. One of the most effective ways of filtering solid particles or liquid droplets is the use of filter media. Currently, all automotive engines, whether gasoline or diesel, come with filtration device to improve oil cleanliness and thus extend the life of the engine resulting in total annual oil filter sales of about 425 million only in the US. In this research, a new proprietary design of concentric coalescer and separator filter in one single unit will be tested by varying different operating conditions. This design is expected to have much lower pressure drop and will be more compact compared to the existing designs. In addition, process models based on convection-diffusion equation in porous media will be developed to determine permeability as a function of thickness of the membrane material, oil properties, and operating variables, and will be validated using experimental data.
