Improvement of heat exchangers for small air separation units

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

DEAR air separation adopts the "software and hardware integration" scheme to implement the energy-saving transformation of air separation. Under normal conditions, the transformation can reduce the power consumption by about 15%. The cooperation supports the EMC (energy management contract) mode. The customer does not need to invest in advance, and the two sides share the saved electricity revenue.
