Hi all,

I need to put a vortex breaker in a vertical separator. How do i determine the distance from the nozzle for placement? Is there is standard or rule of thumb?

Your guidence is much appreciated.
Many thanks,
Sophia

I have seen them installed either right against the outlet nozzle (i.e. no clearance) or lifted 50 to 80 mm. Mostly it depends on the contents of the vessel and the need for draining. If the liquid is a slurry I would lift the vortex breaker off the bottom to allow flushing and draining. If you are using a proprietary unit then follow the supplier's recommendation.

Hi,
Thanks so much for yor responce.
The liquid i'm working with is condensate so i think the 50-80mm would be ok ofr an initial estimate.

Thanks again,
Sophia

Sophia,

Vortex breaker can be flushing and non-flushing type. Flushing type is the type that indicated by katmar. General purpose.

Non-flushing type is applicable to those fluid with solid i.e condensate with sand particle. The sand and particle is preferably to settle at the bottom of separator rather than flushing into the downstream equipment. Thus, non-flushing type is used.

Hi,
Thanks Joe,
I will specify this in my design because i haven't seen any deposits in the separators for this service. Usually it's water with traces of methanol and ethanol from the process.
