Regarding oxygen enrichment
Thread Content
Are there various processes for pressure swing adsorption available on the market these days? I’ve been researching oxygen enrichment recently, and I found that the conversion efficiency is very low – according to some manufacturers, it’s only around 8%. This makes it difficult to achieve a moderate level of oxygen enrichment. We want to achieve an air flow rate of over 2000, with an oxygen concentration of 28%; this requires a large amount of adsorbent, which takes up a lot of space. Additionally, the compressor needs to have high power, resulting in high electricity costs. Do any of you have any good suggestions? Or is it just that my knowledge is limited?
At an oxygen concentration of 28%, the demand for adsorbents is not very high; currently, many applications require 93% oxygen, which results in a slightly higher amount of molecular sieve being needed；
2000 air volume – energy savings through VPSA
Variable-frequency screw air compressors are more efficient and energy-saving, using 33% less energy compared to conventional machines. Moreover, there are now air compressors with first-class energy efficiency, which are even more power-efficient.
