LP Separators
Hi all,
Is there a rule of thumb for tolerable LP separator pressure fluctuation during operation and pull down rates to prevent pump cavitation?
I seem to recall 10 psi/minute or maybe it was 10kPa/minute. What are the pros and cons for vertical vs horizontal other than to suit available space? Vertical for recips because of stepped loading?
I'm talking ammonia at -20 to -30 evaporating.
