Intermittent isolation air supply behind the centrifugal compressor
Thread Content
How should a disruption in the backpressure isolation air supply of a centrifugal compressor be handled? What is the minimum allowable level for this backpressure isolation air?
The data provided by different compressor manufacturers vary. If the rear isolation air supply is interrupted, the secondary air supply should also be interrupted as well; in that case, oil and gas will definitely mix into the air stream
