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 …

In the last years membrane processes for gas separation are gaining a larger acceptance in
industry and in the market are competing with consolidated operations such as pressure …

Zeolitic imidazolate frameworks (ZIFs), that have the potential for gas separation, were used
as additives in mixed-matrix membranes (MMMs). ZIF-8, which exhibits the sodalite …

Efficient separation technologies are required for the removal of carbon dioxide from natural
gas streams. Membrane-based natural gas separation has emerged as one of the fastest …

For gas separation membranes, materials are required that offer high permeability as well as
good selectivity for a desired separation. For glassy polymers, the gas transport properties …

Membrane technology is a very emerging industrial process offering significant advantages
