New Polymer Membrane Could Cut Energy and Water Use in Oil Refining→
/
Researchers at Georgia Institute of Technology (Georgia Tech) have created a new kind of polymer membrane that could reshape how refineries process crude oil, dramatically reducing the energy and water required while extracting even more useful materials.
Read MoreNew Polymer Membranes, AI Predictions Could Dramatically Reduce Energy, Water Use in Oil Refining→
/
Georgia Tech researchers Ryan Lively, M.G. Finn, and Rampi Ramprasad have created a new kind of polymer membrane for separating crude oil into useful components. The membrane could greatly reduce the energy necessary for those initial separations. They’ve also created artificial intelligence tools to predict the performance of these kinds of polymer membranes, which could accelerate development of new ones.

/A Lively lab team, led by Haley White, developed rigid, carbon membranes that effectively remove and concentrate small organic molecules (such as solvents) from water. The potential applications for these membranes are wide-ranging, with particular promise in biorefineries where valuable organic species are often highly dilute in aqueous media.

/
Existing flow battery technologies cost more than $200/kilowatt hour and are too expensive for practical application. The Lively and Liu labs developed a compact flow battery cell configuration that relies on hollow fibers for a sub-millimeter, bundled microtubular (SBMT) membrane.
The new design lowers membrane-to-membrane distance by 100 times, reduces the size of the cell by 75%, and ultimately decreases the size and cost of the entire flow battery. Read more in this news article, and check out the article in PNAS here.

First synthetic membrane to separate crude oil and crude oil fractions
/
Scientists from the Georgia Institute Technology, Imperial College London, and ExxonMobil have developed the first synthetic membrane to separate crude oil and crude oil fractions to reduce carbon emissions and energy use associated with refining crude oil. Tech technology substitutes the low-energy membranes for specific steps in the refining process. It is expected to contribute to a hybrid refining system that could help reduce carbon emissions and energy consumption significantly compared to traditional refining processes.
