Robeson's upper bound
Did you know?
WebFor our purposes, the most important characteristic about this plot is the upper bound, also called the Robeson limit. This is not a true limit, since many novel membrane materials have been crafted that exceed this limit … WebIn the related field of membrane science, the ‘Robeson upper bound’ empirically describes the trade-off between gas permeability and selectivity and has become a ubiquitous tool for comparing membrane materials.

WebJul 14, 2008 · The empirical upper bound relationship for membrane separation of gases initially published in 1991 has been reviewed with the myriad of data now presently available. The upper bound correlation follows the relationship P i = k α i j n , where Pi is the permeability of the fast gas, αij (Pi/Pj) is the separation factor, k is referred to as the “front …
