Membrane technology is regarded as an emerging gas separation technique in the industry due to the lower cost in both initial capital and energy consumption, if compared to cryogenic distillation and pressure swing adsorption. The typical design of the membrane gas separation technique is that the air is drawn from the ambient into the membrane module and the targeted gases are separated based on the difference in diffusivity and solubility. In the membrane module, oxygen will be separated from the ambient air and collected at the upstream due to the high diffusivity, whereas nitrogen will be collected at the downstream of the module.
A Nitrogen generator using membrane technology has the following characteristics:
Least expensive N2 production method
High N2 purities, or high N2 volumes at lower purity levels
High reliability due to simple airflow design
Utilizes lower operating and delivery pressures
Salient Features
Cost-effective gas supply Standard, pre-engineered product range.
Less power consumption hence low operating cost.
No moving parts thus negligible maintenance is required.
Easy to handle and maintain
Highly skidded, modular design ready for installation supplied from factory.
Lower Space Requirement.
Fully automated controls for unattended operation.
