What are the relevant operations for the crude argon column in the internal compression process? ? ?
Thread Content
Everyone, is there anyone who uses a process with an internal compression belt in the crude argon tower? Is that tower used on a regular basis? Does the operation of the crude argon column have a significant impact on the entire system? Are we planning to isolate the crude argon column from the system and stop using it altogether?
How much space is needed? It is possible to omit the crude argon column.
15000 – the key question is whether it has an impact on the purity of oxygen? ! According to the information, without extracting the argon fraction, dual-high quality products cannot be obtained.
To be honest, I plan to do the same, but ours has an external compression of 4500
Of course not. Think about it: when argon is being fed into the tower, if no liquid argon is produced for an extended period of time and no oxygen is vented, the purity of oxygen decreases. Generally, crude argon accounts for about 21% of the total air entering the tower; such a large amount of this gas remaining in the upper part of the tower will inevitably lead to a decrease in oxygen purity if it isn’t utilized
Under high-load conditions, the oxygen purity can drop significantly. Are there any empirical data on this?
It’s okay not to use this crude argon, but the oxygen purity needs to be reduced. Make sure to increase the nitrogen production appropriately, otherwise nitrogen blockage may occur; you can gradually conduct load tests to find out more
Ours is 120,000; we didn’t produce liquid argon before, but we do now. It still involves the production of high-purity liquid nitrogen and liquid oxygen.
Can a nitrogen plug occur even when the argon system is isolated?
