Article Synopsis
- Separation processes become more challenging when the species to be separated is at low concentrations, requiring the overcoming of thermodynamic and kinetic constraints.
- Researchers have developed a molten-carbonate membrane capable of increasing CO concentration from a low level (400 ppm) by using ambient energy from humidity differences.
- This method not only allows CO to move 'uphill' against its concentration gradient but also significantly enhances CO transport rates through the creation of carriers within the molten salt, leading to a tenfold increase in CO flux even with a drastic reduction in input concentration.
Measuring Membrane Permeation Rates through the Optical Visualization of a Single Pore.

Membranes are a critical technology for energy-efficient separation processes. The routine method of evaluating membrane performance is a permeation measurement. However, such measurements can be limited in terms of their utility: membrane microstructure is often poorly characterized; membranes or sealants leak; and conditions in the gas phase are poorly controlled and frequently far-removed from the conditions employed in the majority of real processes.
