Gas Compressor Surge Analysis Steps

10/08/2012 4:19 AM

Hello All,

I am required to size and select a new gas turbine driven Centrifugal Gas Compressor and also carry out Surge analysis and write a technical report on the findings. I only have issues with the Surge Analysis as it will be a first time.

Please i need tips, parameters to look out for, sample analysis software, inputs, expected outputs, result interpretation etc from anyone with a good idea on how to go about this task.

I'll also appreciate if i can get links to sample reports, calculation spreadsheets or any document for that matter that may be of help

I think you have to plot surge curve to draw limiting line for surge protection. for this you have to practically surge the machine by gradually closing the discharge valve at different capacities like 60%, 80%, 100% & 110% of rated capacities (or as desired by customer).

For electric driven machines it is carried out at different openings of suction throttle or inlet guide vanes. But for turbine driven machines it can be done at different operating speeds. Consult manufacturer/ read instruction manual.
