Thanks for your reply.
It was suggested to use the AGA-3 method to size the orifice to achieve a flow rate less than the tanks flame arrestor relieving capacity.
Is the AGA-3 equation a good approximation for flow rate in this case?
Thank you.
I’m not sure I can share a P&ID so let’s go with no on that. There is a flange at the spec break where piping design changes from 600 class to 150 class which is where I believe the orifice should go.
Ideally, the vendor would do it but this was done 11 years ago and URS is no...
Hi All,
I have a natural gas compressor site where the liquid dump lines from the sumps on natural gas scrubbers are plumbed into an atmospheric liquids holding tank. Some of the lines have restricting orifice plates and others don’t. Are the orifice plates needed/required? I was told they...
