Trace oxygen analysis in the crude argon column
Thread Content
To maintain the liquid level in the second crude argon tower, it is necessary to keep the resistance in that tower at an appropriate level. However, if the resistance in the second crude argon tower is too high, the oxygen content in the output from the first crude argon tower will increase. How can one ensure both the liquid level at the bottom of the two towers and a lower oxygen content in the output from the first crude argon tower?
As long as the resistance in the two towers reaches the design value, and the amount of argon fraction entering those towers also reaches the design value, the oxygen content in the upper part of Tower 1 will naturally decrease after a few days. Hehe; one can check the pressure behind the argon pump – it needs to be increased gradually.
