Abstract

It can be difficult to separate water and oil emulsions through traditional filtration. Therefore, investigations of filtering using thermo-responsive (TR) polymers, in this case poly(vinyl methyl ether) (PVME), was conducted. It’s hypothesized that below its lower critical solution temperature (LCST), PVME has an affinity for water while oil substances do not. Above the LCST the opposite will be true. To verify this hypothesis, iterations of filtration designs were created to provide optimum control over the parameters to measure flow. The final optimized experimental apparatus was a Chromaflex glass column which was air tight and controlled all parameters besides fluid flow. Using membranes and sponges, primarily thin sponge and grade 1 Whatman filter paper with various modifications, it was shown that porosity has a directly proportional effect on the volumetric flow rate. It was further shown that, after PVME modification with 3-aminopropyltriethoxy silane (APTES) as the bonding agent, room temperature water flow rate remained constant or increased while diesel flow rate decreased by at least a third. These changes in flow show that PVME has an affinity for water and not oil at room temperature. More experimentation would need to be conducted to prove the TR behavior above the LCST.
