This Small Business Technology Transfer (STTR) Phase I project will introduce a simple online system to continuously remove dissolved water and oxygen from transformer oil. The insulating materials used in large transformers consist of paper and dielectric oils, which provide a means of cooling. Over time, the insulating materials degrade as a result of chemical attack associated with the paper and small reactive molecules within the transformer oil.This technology addresses intermediate size markets (eg. transformer oil) and many very large markets of national interest. This product will first and foremost be an excellent tool for extending the useful life of transformers. There are many other potential applications, such as: removal of dissolved water from hydraulic fluids biodegradable hydraulic fluids; removal of water at low concentrations from products such as fuel grade ethanol; regeneration of solvents due to the stability and high permeability of the membrane at low water activity; and enhancement of chemical reactions by water removal which can drive equilibrium reactions.

这个小型企业技术转让(STTR)第一阶段项目将引入一种简单的在线系统，以连续去除变压器油中的溶解水和氧气。用于大型变压器的绝缘材料由纸和绝缘油组成，它们提供了一种冷却手段。随着时间的推移，绝缘材料由于与纸和变压器油中的小活性分子相关的化学侵蚀而降解。变压器油)和许多涉及国家利益的非常大的市场。该产品将首先成为延长变压器使用寿命的优秀工具。还有许多其他潜在的应用，如：从液压油中去除溶解水；从可生物降解的液压油中去除低浓度的水；从燃料级乙醇等产品中去除低浓度的水；由于膜在低水活度下的稳定性和高渗透性而再生溶剂；以及通过去除水来促进化学反应，从而促进平衡反应。
