The issue of air consumption ratio in PSA nitrogen generators
Thread Content
I would like to ask the experts: when using the domestic CMS2-220 system, what are the power consumption ratios for nitrogen generators with purities of 99.9% and 99.95%? Is there a precise formula for this, or is it merely based on experience?
It should be the design value; specifically, it also depends on whether that value is achieved, which is one of the acceptance criteria after completion. The data is all calculated, but there are differences in the accuracy of data collection. Especially the air flow meter. If you’re looking for formulas, they can be found in the books “Oxygen Production Technology” and “Questions and Answers for Oxygen Production Workers”. The key is to ensure that everything is in line with the design specified in the contract.
Currently, the figures provided by the two suppliers differ significantly; one states that the 99.9 idle ratio is 3.5, while the other says it is 4.5 – the difference is quite large
Based on our company’s actual production processes, the nitrogen-to-air ratio of the molecular sieve of the model mentioned by the original poster is around 3.7. My QQ number is 1812287119; we can discuss this further.
