Membrane Separation Technology

Nitrogen Generators by Membrane Separation is the most common type of nitrogen generator where high nitrogen purity is not a critical requirement. Considering the economic performance, most economically sound is the use of air separation plants for nitrogen generation designed on the basis of hollow-fiber polymer membranes. If 95%-99.9% pure gaseous nitrogen is required where capacity rate does not exceed 1000 nm³/hr, membrane air separation technology appears to be the most suitable option. Considering the economic performance, most economically sound is the use of air separation plants for nitrogen generation designed on the basis of hollow-fiber polymer membranes. Membrane air separation technology The operation of membrane systems is based on the principle of differential velocity with which various gas mixture components permeate membrane substance. The driving force in the gas separation process is the difference in partial pressures on different membrane sides.A hollow-fiber membrane represents a cylindrical cartridge functioning as a spool with specifically reeled polymer fibers. Gas flow is supplied under pressure into a bundle of membrane fibers. Due to the difference in partial pressures on the external and internal membrane surface gas flow separation is accomplished. Membrane technology is characterized by low power consumption and the absence of moving parts.

Nitrogen Generator Components

PSA Nitrogen Generator can be divided into three units: Air compressor and purification system Oxygen and nitrogen separation unit Nitrogen storage and flow control system

Benefits of using PSA Nitrogen Generator

High Reliability: Proven PSA technology, simple engineering design, few moving parts and international standardized manufacturing techniques ensure minimal maintenance and maximum reliability. Low Cost: Patented high-efficiency control system reduces air consumption, and saves power. Automatic Control: Unattended operation fully controlled by PLC automatically. Touch-screen control, display and alarm system enables the system to be operated by one touch. Display also show working parameters, and provides filter changing reminders, and trouble shooting instructions. Easy Installation: Skid mounted for easy installation and movement. Long Service-life: Exclusive bed containment system extends Carbon Molecular Sieve (CMS) bed life to more than ten years. Minimal Maintenance: The generator has highly-reliable valves and no other moving parts. Filter elements are easily replaced.
