Abstract

The first scientific observation related to gas separation was encountered by J.K Mitchell in 1831.
However, the most remarkable and influential contribution to membrane gas separation technology was
the systematic study by Thomas Graham in 1860. However only in 1979, membrane based gas separation
technology was available and recognized as one of the most recent and advanced unit operations for gas
separation processes. Membrane is fabricated by various methods and the parameters involved to a certain
extent are very complicated. The phase inversion technique that is normally employed to produce membranes are dry/wet, wet, dry and thermal induced phase separation. Other techniques used to produce
membrane are also reviewed. This paper reports the latest development in membrane formation for gas
separation. The route to produce defect-free and ultrathin-skinned asymmetric membrane is also presented
that represents the cutting edge technology in membrane gas separation process.
