The Feed gas and cold source of the crude argon tower come from the main tower and return to the main tower, so the crude argon Tower and the main tower are closely related and affect each other. The input of crude argon tower should have the following conditions: 1) the working condition of main tower is stable; 2) the output and quality of oxygen and nitrogen products are close to or reach the normal value; 3) the argon content of argon fraction is close to normal; 4) the main cooling liquid level is relatively high with sufficient cooling capacity. In the process of the crude argon tower being put into use, first lead out the argon distillation to precool the crude argon Tower, and then gradually send the liquid air to the crude argon condenser. With the chilling of the crude argon Tower, the rectifying working condition is gradually established in the crude argon tower. Its mark is that the resistance of the crude argon Tower, the purity of the crude argon and the extraction amo...

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...
