Optimization design of air separation equipment

Answer: Kaifeng deer air separation has the first complete intelligent production line of fractionator recognized by the industry in China (put into construction in 2019) Positioning: full automatic production line of cold box/fractionator cylinder, three-dimensional warehouse AGV、 Robot welding, visual blanking, mes+"Deere smart brain", continuous plate cutting, rounding, welding, film washing, and pipe Island assembly, not piecemeal robot transformation. Key points: it is the first recognized intelligent production line of air separation equipment in the air separation circle, especially for the aluminum alloy tower of air separation.

In the main column of the air separation column, the distribution of argon varies with the position of the liquid air inlet. With the increase of liquid air inlet position, the maximum concentration of argon enrichment zone in the stripping section also increases, and the nitrogen content in the distillate can be reduced. However, the argon content in the downstream also increases. In order to ensure the purity of oxygen, more trays are needed under the extraction port of argon fraction. Therefore, in the case of producing argon, the position of liquid air supply E1 should be appropriately increased compared with the case of not producing argon. Some unit is equipped with two liquid air inlet positions to meet the conditions of argon production and non argon production respectively. In the production of argon, in order to improve the extraction rate of argon, the content of argon in oxygen and nitrogen must be reduced. When the content of argon in exhaust nitrogen is more than 0.3%
