NITROGEN SERIES GENERATOR
Pressure swing adsorption
NITROGEN GENERATOR INTRODUCTION
PSA nitrogen generator is a machine producing nitrogen by separating nitrogen from air. It adopts the principle of PSA (pressure swing adsorption). Pressure swing adsorption processes rely on the fact that under pressure, gases tend to be attracted to solid surfaces, or “adsorbed”. The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or desorbed.
PSA processes can be used to separate gases in a mixture because different gases tend to be attracted to different solid Surfaces. When air is passed under pressure through a vessel containing an adsorbent (zeolite molecular sieve) bed that attracts nitrogen more strongly than it attracts nitrogen, part or all of the nitrogen will stay in the bed, and the gas coming out of the vessel will be enriched in oxygen. When the bed reaches the end of its capacity to adsorb nitrogen, it can be regenerated by reducing the pressure, thereby releasing the adsorbed nitrogen. It is then ready for another cycle of producing nitrogen. In this way, high purity nitrogen is produced
PSA TECHNOLOGY
BASIC STRUCTURE
A complete nitrogen generator consists of: Air compressor, Air Treatment Circuit, Air Receivers, PSA Nitrogen generator, Nitrogen Receiver, Super Charger Compressors and Medical Filtration.
*This photo is for explanation only, real machine structure will be based on flow rate and site space, etc
AIR COMPRESSOR
Air compressor provides compressed air source for the PSA nitrogen generation part, the flow and pressure are to be decided by the desired nitrogen flow rate, purity, outlet pressure. As it is the air source of whole system, the performance of air compressor has remarkable influence to the whole nitrogen generator system.
AIR TREATMENT CIRCUIT
To get rid of water, oil, impurities in compressed air coming from the air compressor, providing clean, dry, oil-free compressed air for the PSA nitrogen generation part. It includes 3 filters, 1 refrigerated dryer and 1 activated carbon oil remover. After treatment, dew point of compressed air can reach -20 degree (normal pressure), dust content is not larger than 0.01mg/m3, solid particles diameter is not larger than 0.01μ, oil mist content is not more than 0.003mg/m3.
PSA SEPARATION
It is the key part of whole system. In this part, the oxygen is separated from compressed air, sent to buffer tank as produced gas. Nitrogen, carbon dioxide, argon,etc are discharge from muffler as exhausted gases. The efficiency of this machine is mainly decided by adsorption tower structure, air distribution structure, molecular sieve performance, process flow, etc
PRODUCT DETAILS
HIGH RELIABILITY
Proven PSA technologies such as big flange structure, snowstorm filling, gas distribution system, gas speed control technology, unequal pressure balance system, etc make REINIGEN Gas nitrogen generator more reliable.
EASY INSTALLATION
Skid structure, fully assembled and test qualified before delivery. When machine reaches site, with simple connection of power supply and gas pipeline, the machine is ready for operation. No need to disassemble and/or re-assembly at site.
MINIMIZED MAINTENANCE
After 8000 hours operation, simply replace the three filter elements and activated carbon for air treatment part, no other regular maintenance needed
LOW OPERATION COST
With REINIGEN LUFT technologies, producing same flow rate, same purity oxygen, smaller compressed air is needed, saving customer air compressor electricity consumption cost every day.
