Vortex Breaker in EFR Tanks
Vortex Breaker in EFR Tanks
(OP)
Hi for everyone!, Regarding this matter somebody could help me? it is necessary the installation of a vortex breaker in inlet pipe when a EFR is designed?. How can i design it? API 650 does not make some reference! the Floating Roof could be damaged without VB? The EFR is Double Deck type, Tank Dia= 240 ft, Cap=500,000 Bls.
Thanks in advance

I also tend to agree with Joe that vortex breakers are usually seen at outlets, not inlets. When liquid is withdrawn from a tank or vessel, vortexing could cause some problems like allowing vapor into a pump which could cause cavitation. The process engineer is the one who specifies if a vortex breaker is required because they are the ones who do those hydraulic calculations.

I think you could solve your problem by using an inlet diffuser and directing the flow velocity and direction (away from seals).
