Rich gas compressor isolation gas pressure

The supply pressure for lubricating oil is generally around 0.15 MPa, while 0.4 MPa is sufficient for the isolation gas. It’s best to ask the dry gas seal manufacturer for these values; they can provide them, so as to avoid disputes in the future
What level of pressure is everyone controlling?
In my opinion, it should be the equipment manufacturer who provides this information; it all needs to be clearly stated in the equipment’s user manual. They will be held responsible if something goes wrong. Discussing such issues here presents the problem of various device formats. It’s better to consult the manufacturer and obtain written documentation so that there is evidence to rely on and something that can be checked.
Some of the data from the time of production is no longer available; I’m just asking everyone what the control pressure at the site is, as a reference
0.02Mpa—0.03Mpa is sufficient
0.02Mpa—0.03Mpa is sufficient
The isolation gas needs to be at 20 kPa, that’s sufficient
Is everyone’s level this low? The pressure at our site is 0.27 MPa
