Scientists discover that a clogged filter could revolutionize oil refining

By · Published by Everything Blog

In short

Engineering teams from KAIST and Georgia Tech have engineered a low-cost membrane from porous polyacrylonitrile that separates crude oil at room temperature. The innovation transforms conventional fouling into an operational benefit by letting heavy hydrocarbons naturally narrow membrane pores. This breakthrough provides an alternative to traditional, heat-heavy distillation, significantly lowering industrial energy requirements and associated carbon output. By replacing thermal methods that demand temperatures above 350 degrees Celsius, the system achieves molecular separation without costly engineered coatings.

Researchers have developed a surprisingly simple way to separate crude oil without heating it, potentially transforming one of the world's most energy-intensive industrial processes. The breakthrough uses an inexpensive membrane that could significantly reduce the energy required for oil refining while lowering operating costs and carbon emissions.

The international research effort was led by Professor Dong-Yeun Koh at the Korea Advanced Institute of Science and Technology, known as KAIST, in collaboration with Professor Ryan Lively's research group at Georgia Tech. KAIST(President Kwang Hyung Lee) announced that the team had successfully demonstrated a membrane capable of separating crude oil at room temperature. The findings were published…
