The expansion air volume entering the upper tower increases, and the reflux ratio of the distillation section decreases correspondingly. In order to achieve the required purity of nitrogen products, more tower plates need to be set. When the reflux ratio is reduced to countless Tower plates needed to be set to make the purity of nitrogen reach the required value, then the reflux ratio is called the minimum reflux ratio. The expansion air volume entering the upper tower is first limited by the minimum reflux ratio. The closer the reflux ratio is to the minimum reflux ratio, the faster the number of tower plates needed to ensure the product purity increases, which will lead to the increase of investment, the increase of tower plate resistance, the increase of Operation pressure and the increase of energy consumption. Therefore, the reflux ratio after the inflated air enters the tower should be larger than the minimum reflux ratio. When the purity of nitrogen is required to be low, the...

Switching purification process air separation equipment refers to self-cleaning of moisture and carbon dioxide in the passageway of switching Plate-fin Heat Exchanger (or cooler) through switching valve. Switching purification process the air separation equipment mostly adopts the method of circulation or extraction to reduce the temperature difference of the cold end of the Plate-fin Heat Exchanger (or the cooler); it adopts the expansion heat exchanger to recover the cooling, further reduce the temperature of the expansion gas; use the liquid supercooler to further reduce the liquid temperature of the throttle entering the upper tower. Therefore, when switching purification process air separation plant restarts and starts after short-term parking, attention should be paid to: 1) before recovery, the start-up circuit should be determined according to the recovery situation of cold end temperature; 2) for the air separation equipment with liquid supercooler, a part of the liquid fro...
