Pressure Swing Adsorption (PSA) nitrogen generation is a well-established and highly efficient technology based on the selective adsorption of gas molecules. Using high-quality carbon molecular sieves (CMS), compressed air is separated into its components by adsorbing oxygen, carbon dioxide, and moisture under pressure, while nitrogen passes through as the primary product. Through a cyclic process of pressurization and regeneration and the use of a nitrogen mixing vessel, the system delivers a continuous and stable flow of high-purity nitrogen. HADETEC PSA nitrogen generation packages are engineered for maximum performance, flexibility, and long-term reliability. By carefully selecting premium molecular sieve materials from leading manufacturers and combining this with advanced system design and engineering expertise, we ensure optimal efficiency and consistent product quality under all operating conditions. PSA technology is particularly suited for applications requiring high-purity nitrogen. Compared to membrane systems, PSA offers superior purity levels, making it ideal for critical processes where nitrogen quality is essential. Depending on your process requirements, HADETEC PSA systems can achieve nitrogen purity levels up to 99.999% N₂ (10 PPM oxygen content).

Our PSA systems are designed with modularity and scalability in mind, allowing for easy capacity expansion and adaptation to changing operational needs. While single-unit capacity has practical limits, multi-train configurations can be implemented to meet higher demand requirements.

With HADETEC, you benefit from a robust, high-performance nitrogen generation solution that ensures maximum purity, operational reliability, and cost efficiency.

A typical PSA type Nitrogen Generator includes:

• Pre-filtration / coalescing filter
• Twin tower adsorber beds with carbon molecular sieve (CMS)
• Nitrogen mixing vessel
• After filtration / particle filter
• Equalization and vent systems
• Product / off-spec line
• Interconnecting piping with isolation valves, control valves & relief valves
• Field instruments including pressure, temperature, and flow measurement
• Online oxygen analyzer(s) for continuous purity monitoring
• Local control panel with indication, control & HMI interface compatible with plant DCS
• Nitrogen receiver (if applicable)

For onshore applications, HADETEC Nitrogen Generators are designed to operate reliably in harsh environments such as dusty, sandy, and high-temperature conditions, including hazardous classified areas. For offshore installations, designs focus on compactness, corrosion resistance, and durability to withstand marine conditions and limited available space.

Optional:

• Integrated air compressor
• Integrated air dryer
• Wet Air or Instrument Air receiver
