For air distillation, we usually use the air inlet to distinguish the distillation section and the stripping section of the distillation column. The distillation section is above the air inlet, and the stripping section is below the air inlet. There are two argon enrichment zones in the upper column of the double column process, one is the distillation section above the air inlet.
Some experts believe that the new single column process is the same as the double column process, because of the dilution effect of air, there should be two argon enrichment areas. The reason why there are two argon enrichment zones in the double column process is not only due to the dilution effect of air. The upper column of the double column process is nitrogen argon oxygen air separation column. In addition, the effect of oxygen enriched liquid air is also a major factor. The argon content in the oxygen enriched liquid air is about 2% and the quantity is large, which has a significant impact on the distribution of argon in the upper column, It is the key factor for the formation of two ar enrichment zones in the upper column of the double column process.
Patent for ultra low pressure discharge and energy saving
The company has a number of patented technologies, of which two ultra-low pressure discharge energy-saving patents are domestic leading level, which can reduce the energy consumption of air separation plant by 5% - 15% and save operating costs.
