Types and Module Configurations

Membranes can be made as flat sheets in long rolls or in the form of thin, hollow tubes. Production of current gas-separation membrane modules is divided approxi- 

2) Permeance is permeability divided by the thickness of the membrane material. 

Permeance is expressed in terms of gas permeation units (gpu), defined as 1 x 1 x 10-6 cm3 (STP)/cm2 scmHg.
