The problem with the distillation tower is extremely urgent
Thread Content
We have two carbon steel packed towers, which have been installed (including packing), but there are still five months until the commissioning. How do we protect the packed towers now, because our materials cannot contact water and will react when exposed to water, which may cause the packed towers to become clogged. And rust will also easily block our packing tower. Thanks!
Fill with nitrogen! ! ! ! ! ! ! ! ! Dry the tower first, and then fill it with nitrogen for protection after drying thoroughly. :) :)
Do you agree with the approach above? It seems to be the only approach? If no water has entered before, use the method of vacuuming and N2 replacement to make O2
I don’t know what media the poster mentioned that the packed tower handles. Is vacuuming and nitrogen blowing of the packed tower used in the purification process solution system a good method? You can also consider using heated nitrogen blowing. If the process conditions permit, this can come quickly.
Nitrogen sealing, this method is basically used

Yes~~~~ While vacuuming~~~~~ and flushing nitrogen~~~Nitrogen sealing~~~
First of all, you should ensure that the sealing of the tower and pipelines meets your requirements. According to the original poster, the sealing requirements of this tower should be higher, so on the basis of ensuring the sealing, nitrogen protection (the tower needs to be dried) or vacuumed!
Summarize the highlights of famous places upstairs: Dry nitrogen, nitrogen sealing, ensuring air tightness is more important
Isolate the blind plate of the process pipeline connected to the tower, and maintain the pressure at 0.2 kg after passing nitrogen replacement.
There must be no rust or water. The tower body should be chemically cleaned, then replaced with nitrogen, and the oxygen content and water content should be analyzed. After passing the test, the pressure should be maintained and analyzed regularly.
Fill with nitrogen and turn on vacuum...success immediately: lol
agree! :lol :lol :lol
Is filling with nitrogen dangerous to future operators? Will it cause suffocation to the operator?
After filling with nitrogen, it is sealed and isolated, which will not pose any danger to the operators. Of course, the operators must not enter the tower.
Nitrogen filling is done, but the tower needs to be thoroughly cleaned before nitrogen filling. There must be no rust
Isolate the tower first, then vacuum it to make it airtight and seal it with N2.
Of course, nitrogen sealing. . . . . No need to think about it. .
