Energy Efficient Separations of Olefins and Paraffins through a membrane
Developing membranes with sufficient performance and ability to operate over long time periods in a real world environment
The commercial benefit of a technology to separate olefins and paraffins through a membrane is potentially very large. Light olefins are one of the most important chemical markets globally, approaching 200 million metric tons of propylene and ethylene production in 2018. These molecules are extremely important due to their status as building blocks for numerous petrochemicals including polyethylene and polypropylene. Currently, these molecules are separated from each other using distillation, an energy-intensive process that is estimated to consume 0.3% of the world’s energy. While many of the early applications will take place in cooperation with distillation, as the membrane technology developing under this project becomes more accepted and proven it may come in direct competition with distillation for new builds.
