Suzhou nitrogen generator: the main classification of nitrogen generator

Cryogenic air separation nitrogen production: Cryogenic air separation nitrogen production is a traditional nitrogen production method with a history of nearly several decades. It uses air as raw material, after compression, purification, and then use heat exchange to liquefy the air into liquid air.

Molecular sieve air separation nitrogen production: using air as raw material, carbon molecular sieve as adsorbent, using pressure swing adsorption principle, using carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen, commonly known as PSA nitrogen production. This method is a new nitrogen production technology developed rapidly in the 1970s.

      Membrane air separation nitrogen production: using air as raw material, under certain pressure conditions, oxygen and nitrogen and other gases with different properties have different permeation rates in the membrane to separate oxygen and nitrogen. Compared with other nitrogen making equipment, it has the advantages of simpler structure, smaller volume, no switching valve, less maintenance, faster gas production (≤3 minutes), convenient capacity expansion, etc. It is especially suitable for nitrogen purity ≤ 98% of medium and small nitrogen users have the best feature-price ratio. When the nitrogen purity is above 98%, its price is more than 15% higher than that of the PSA nitrogen generator of the same specification.
