Membrane Nitrogen Generator

Membrane Nitrogen Generator

A Membrane Nitrogen Generator is an advanced system used to produce high-purity nitrogen gas from compressed air using selective gas separation membranes. These generators are widely used in various industries such as food packaging, electronics, pharmaceuticals, and chemical processing due to their reliability, low maintenance, and cost-effective operation.

Working Principle

1. Compressed Air Supply: The system starts with a high-quality compressed air source, which is pre-treated using filters and dryers to remove contaminants such as dust, oil, and moisture.
2. Selective Permeation: The air passes through a specially designed hollow fiber membrane module, which selectively allows oxygen, carbon dioxide, and water vapor to permeate through the membrane walls, while nitrogen remains trapped and flows out as a purified gas.
3. Purity Control: The purity of nitrogen can be controlled by adjusting parameters such as airflow rate and membrane length.
4. Typical nitrogen purity levels range from 95% to 99.9% depending on the application.

Key Features & Benefits

• Compact & Lightweight: Requires minimal space and is easy to install.
• Low Maintenance: No moving parts, reducing the need for frequent maintenance.
• Continuous Operation: Provides an uninterrupted nitrogen supply without the need for refilling cylinders.
• Energy Efficient: Consumes less power compared to other nitrogen generation methods like PSA systems.
• Customizable Purity Levels: Can be tailored to specific industry needs.

Applications

• Food & Beverage Industry: Modified Atmosphere Packaging (MAP) for food preservation.
• Pharmaceutical & Laboratory Use: Inert atmosphere for sensitive processes.
• Electronics & Semiconductor: Preventing oxidation during manufacturing.
• Oil & Gas Industry: Inerting and blanketing applications.
• Automotive & Aerospace: Tire inflation and fuel tank blanketing.

Membrane Nitrogen Generators offer a cost-effective, efficient, and eco-friendly alternative to traditional nitrogen supply methods such as gas cylinders or liquid nitrogen tanks .
