Frequent fluctuations in the argon column
Thread Content
An oxygen generator with full low-pressure external compression of 12,000 experiences significant fluctuations in its argon system during the summer months, which in turn affects fluctuations throughout the entire system. The flow rate of crude argon drops from 11,000 to just over 3,000, with such fluctuations occurring multiple times per minute. What could be the cause of this?
What about the data for the crude argon condensation evaporator? Is it stable?
It’s probably nitrogen plugging caused by insufficient air handling capacity in summer
The air separation main tower serves as the foundation; for the argon tower to be stable, it is crucial that the main tower remains stable. If there are more detailed details, let’s discuss them together
Too much expanded gas is entering the upper tower; it is recommended to increase the bypass flow.
The instability of the argon system is generally a direct reflection of the operating conditions of the main tower. If this issue occurs frequently in summer, it may be due to insufficient air supply: high temperatures in summer lead to higher water temperatures, which results in a lower volume of air entering the tower compared to when temperatures are lower. It is recommended to adjust the operating conditions by reducing the amount of air supplied.
