For 100,000 tons of ammonia-alcohol (1:1), using oxygen-enriched gas generation, what is the approximate capacity required for the air separation unit?

To achieve oxygen-enriched continuous gasification, the amount of O2 needed for burning coal during blowing is the same as the oxygen content in the blowing air (in practice, it can be slightly less due to the lack of heat carried away by the N2 in the blowing air, but the difference is not significant)； That is, the amount of O2 required per ton of ammonia is: 2500X0.21=525 m3, which is consistent with the commonly accepted range of 500~550 m3 ； The O2 required for methanol production is roughly equivalent to that amount ； Based on this calculation, the amount of O2 required for 100,000 tons of total ammonia is: 100000X525/(300X24) = 7290 m3/h ； If calculated entirely based on synthetic ammonia, the oxygen content in the air fed into the furnace at that time is 51% ；
