A process for the efficient transfer of molecules between phases employing mesoporous poly (aryl ether ketone) hollow fiber membranes is provided. The method addresses the controlled transfer of reactants into and removal of reaction products from a reaction media and the removal and separation of target molecules from process streams by membrane-assisted liquid-liquid extraction. A number of possible modes of liquid-liquid extraction are possible according to the invention by utilizing porous poly (aryl ether ketone) hollow fiber membranes of Janus-like structure that exhibit a combination of hydrophilic and hydrophobic surface characteristics. The method of the present invention can address the continuous manufacture of chemicals in membrane reactors and is useful for a broad range of separation applications, including separation and recovery of active pharmaceutical ingredients.

A process and system for separating paraxylene from a mixture of paraxylene, metaxylene, orthoxylene, and ethylbenzene in a simulated moving bed apparatus using a membrane to separate non-aromatics from a desorbent stream. The lower nonaromatics content in the desorbent improves paraxylene product purity, increases paraxylene production at the same desorbent rate, reduces the desorbent rate, and/or reduces energy consumption in the product tower.
