Some issues with the nitrogen seal and leak collection tank of reciprocating compressors?
Thread Content
Under normal conditions, medium leakage and nitrogen sealing lower the pressure through leak recovery! If the nitrogen seal fails, where does the process gas leak to? Is it recovered through air leakage, or does it end up in the nitrogen sealing pipeline? Also, is the liquid cut off from the collection tank lubricating oil?
It’s still in Xuji, within the pipeline leading to the low-pressure flare; moreover, the nitrogen seal is equipped with a check valve, so there will be no cross-flow of gas
What about the pipeline after the check valve? Will it interfere? It’s not connected to the nitrogen system!
If it leaks, it can be released into the atmosphere. Of course, the hydrogen in our case is in trace amounts and will not pollute the atmosphere. Most of the liquid in the collection tank is an oily substance.
