2-1 Membrane Type
Following five types of the membrane are available now:
| Membrane
type | High pressure
side of hollow
fiber | Application
for | Limit | | Differential p
ressure bar
(psi) | Temperature
(°C) | | A | outside | H2, He, C02 | 35(500) | 150(300) | | B-L | outside | H2, He, C02 | 35(500) | 150(300) | | B-H | outside | H2, He, C02 | 100(1400) | 100(210) | | C | inside | dehumidification | 10(140) | 100(210) | | D | outside or inside | dehydration | 10(140) | 150(300) |
2-2 Characteristic of Membrane
UBE's membranes characterize properties in various ways, heat resistance, chemicals tolerance, high selective permeability in gas separation, etc. Permeation rates for various gas components of each membrane type are shown in the example permeability data.
2-3 Module Model
Tabulated membrane modules with polyimide hollow fiber are available.
