Energy-saving membrane offers a new alternative to conventional crude oil refining

Researchers from KAIST and Georgia Tech have developed a low-cost porous membrane that separates crude oil at room temperature, potentially replacing the energy-intensive distillation process used in refineries. The membrane works by allowing heavier hydrocarbons to coat its pores, creating tiny channels that filter lighter fuels like gasoline and kerosene. Simulations show it could cut refining energy use by 31.6%, carbon emissions by 37.6%, and operating costs by 36%.
