Distance between surge line and discharge NRV
Distance between surge line and discharge NRV
(OP)
People,
Do you know if it is a requirement that the distance between the compressor surge connection take off from the discharge line and the discharge check valve to be minimum? If so, what is the standard?

Diego

RE: Distance between surge line and discharge NRV
each application/installation is unique and requires careful planning and preparation for proper installation and operation of the entire anti-surge system.
hope this helps.
good luck!

1. Compressor discharge check valve
2. Anti-surge recycle valve (take-off for this, as pmover said, to be upstream of the discharge check valve)
3. Compressor discharge flange
If this inventory isn't minimised the anti-surge control system won't be able to react quickly enough. Get a dynamic simulation done if you can because the worst case will usually be on a trip.
