Why is the pressure in the lower tower of the air separation equipment higher than that in the upper tower?

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.

In terms of technology, different from most manufacturers that only guarantee the output of oxygen and nitrogen, Deere realizes the full extraction of oxygen, nitrogen, argon, helium, neon, krypton and xenon, and the output and purity of various products meet or exceed the contract indicators, so as to fully tap the value of Air Resources. In terms of delivery, the integrated mode reduces the connection problems caused by multi-party subcontracting, shortens the construction cycle, helps customers put into production quickly, and shortens the return on investment cycle. The system energy consumption is stable and meets the contract design standard, and the problem of "paper energy saving, actual high consumption" is eliminated. Intelligence is a highlight. The project applies Deere's self-developed blue bank intelligent operation and maintenance system for the first time, relying on big data, AI model, robot and UAV inspection, to realize real-time monitoring, intelligent analysis and
