Borgman dry gas seal
Thread Content
May I ask whether the dry gas seal booster pump of the Borgmann cyclic hydrogen compressor can be replaced online if it gets damaged while in operation?
No, there is no booster pump; the dry gas seal lacks a pressurization function and therefore cannot be operated.
I mean, once stability is achieved, won’t the booster pump stop operating after the pressure at the compressor outlet reaches the desired level? If the booster pump fails while the unit is running normally…
Don’t settle for a makeshift solution – damage to the dry gas seal cannot be explained otherwise.
Take a look at the on-site procedures: if there are valves that can be shut off, they can be replaced online. The unit operates normally while the booster pump is not in use. Before starting the work, it is necessary to conduct a risk assessment of the relevant construction plan and obtain approval for it.
It can be replaced; once the unit is started normally, the booster pump can be removed
As long as there is a cross-line, it should work; if there’s no cross-line, then it can’t be connected. For a single seal gas stream, it still needs to go through the booster pump process, right?
It is necessary to consider whether the booster pump will start operating in the event of an emergency shutdown during the online replacement process
It can be repaired online, but it is necessary to check the dry gas seal PID. It is also necessary to ensure that the unit does not stop or experience failures during maintenance. If there is a stoppage, the booster pump cannot be used, which may result in no high-pressure gas reaching the dry gas seal. The dry gas seal is not functioning, resulting in gas leakage.
