Nitrogen Purification Skid: Achieving Ultra-High Purity for Critical Manufacturing Processes

Nitrogen Purification Skid: Achieving Ultra-High Purity for Critical Manufacturing Processes

For industries where even trace contaminants can compromise product quality—such as semiconductor fabrication, specific chemical processes, or fiber optic manufacturing—standard PSA purity is often insufficient. Our Nitrogen Purification Skid is the critical secondary stage unit that takes commercial-grade nitrogen, typically generated by a PSA system, and elevates its purity to levels of 99.9999% (six nines) and beyond, while also removing residual impurities like hydrogen, carbon monoxide, and water vapor.

The purification skid employs a sophisticated catalytic and adsorption process. Nitrogen gas from the primary generator is first heated and passed over a catalyst in the presence of a minute amount of hydrogen (which is typically added externally). This catalytic reaction converts residual oxygen into water vapor. The gas is then passed through a twin-tower drying system where the newly formed water vapor is meticulously removed, along with other trace impurities, through specialized desiccants and molecular sieves. The entire process is housed on a compact, integrated skid, complete with all necessary instrumentation, valving, and a PLC control system for fully automatic, continuous operation. This two-stage approach—generation followed by purification—is significantly more energy-efficient than attempting to produce ultra-high purity solely through a high-flow, high-pressure PSA process. Our Nitrogen Purification Skid ensures that your most sensitive and mission-critical applications receive gas purity that is non-negotiable, protecting high-value products and ensuring adherence to the most stringent international quality standards.
