Abstract
Gas–liquid membrane contactor, which integrates
the absorption process with membranes, is an emerging membrane technology that
is of particular interest for acid gas absorption. Authors revies the recent
development of membrane contactor technology.
They analyze key challenges being addressed for
membrane contactor development, and discuss the state-of-the-art of highly
hydrophobic microporous membranes, novel liquid absorbents and membrane module
design and process simulation. They also summarize future opportunities for
achieving breakthrough in membrane contactor that can lead to large-scale
practical applications.
