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...

In the switching heat exchanger, moisture and carbon dioxide cannot be completely and thoroughly removed. Although the remaining amount is very small, it will gradually block the switching heat exchanger over time. In the production, it shows that the resistance of switching heat exchanger increases continuously, the free section of gas flow decreases, and the air volume cannot enter. In addition, in the cold section of the switching heat exchanger, carbon dioxide has been basically cleaned up theoretically, but due to the clamping effect of air flow, the amount of carbon dioxide brought into the tower is much more than the theoretical content. Apart from being partially cleared by the adsorption filter, the rest of the carbon dioxide will gradually accumulate in the tower and block the tower plates, pipelines and valves. In addition, the air also contains a small amount of acetylene and hydrocarbon. Although adsorbed by acetylene adsorber, its adsorption efficiency can only reach a...
