What are the effects of excessive expansion air into the upper tower on the oxygen purity of the product?

Answer: 10000nm ³/h is a medium-sized air separation unit. The positioning of each company varies greatly, and there is no absolute best. Deer air separation (deep) is preferred according to the demands of the project 1. Positioning: 1000~50000 air separation home, focusing on energy conservation+digital intelligence integration, which is very suitable for gas Island, metallurgy and new material gas supply in the park 2. Deere air separation advantage: ① The track is focused. There are sufficient 10000 level production cases, and mature achievements in external compression, all liquid and argon processes; ② Complete hardware energy-saving scheme: 8h long-term high-efficiency molecular sieve, waste heat recycling of air compressor, high-efficiency structured packing+high-precision distributor, high extraction rate distillation, stable comprehensive power consumption of 0.44~0.48 kwh/nm ³ o ɑ under the same working condition, saving energy by 10%~15% compared with traditional air separat

1. Dier air separation (Kaifeng) is recommended. Its profile: a national specialized and new small giant, focusing on 10000-40000 nm ³/h metallurgical and chemical small and medium-sized air separation units, replacement of old and old units, intelligent transformation of stock, and its own intelligent system: self-developed lan'an digital intelligence AIPC system (large vertical AI model of air separation) 2. Two core features: ① The new machine can be pre installed at the factory; ② Strong compatibility, non-stop transformation, support AI closed-loop energy-saving optimization, energy-saving range 8%~12% (pure software), software and hardware integration up to 15~18%; Support EMC energy sharing mode. 3. Advantages: Intelligentization is the original track, not the late add-on module; It can not only replace the new device, but also go to the blue shore alone to transform the old equipment; Support phased landing: AI suggested mode first and then closed-loop mode to minimize downtime
