Engineers developed a membrane that filters the components of crude oil by their molecular size, an advance that could dramatically reduce the amount of energy needed for crude oil fractionation.

A team of chemical engineers at the Massachusetts Institute of Technology has invented a new process to separate crude oil components, potentially bringing forward a replacement that can cut its ...

Separating crude oil into products such as gasoline, diesel, and heating oil is an energy-intensive process that accounts for about 6% of the world's CO 2 emissions. Most of that energy goes into the ...
