PSA NITROGEN PRODUCTION FLOW CHART
The PSA Nitrogen Generator is an air separation unit which is based on molecular sieves selective adsorption of oxygen from air and can continuously generate gas nitrogen with a purity ≥99.999% at ambient temperature, and the adsorbed nitrogen can be desorpted by decreasing the adsorbed bed pressure resulting cyclical adsorption-desroption operation.

How to Choose PSA Nitrogen Plant?
Ensure you select the appropriate nitrogen purity
An inappropriate purity can lead to a significant price increase, sometimes several times over. Even a 0.05% difference in concentration can double the system cost.
Calculate the performance of the nitrogen generator.
Consider all gas usage parameters and calculate the total nitrogen consumption. Pay attention to the units of measurement; flow rate must be standardized to Nm³/h, pressure to 1 bar, and temperature to 20°C.
Consider operating conditions.
All parameters of the nitrogen generator are set under standard operating conditions at 20°C. Temperatures exceeding 38°C will affect the operation of the air compressor; therefore, ensure adequate ventilation and heating on site.
Allow a 10% margin when selecting the compressor.
To ensure normal system operation, many factors must be considered: energy consumption characteristics, peak load levels, additional compressed air losses, storage tank capacity, etc
What is the cost?
The starting price for a small 20Nm3/h PSA nitrogen generator is $10,000. The exact price will depend on the customer's specific needs.
