VORTEX BREAKER

VORTEX BREAKER

VORTEX BREAKER

(OP)
Hello All,

I need to get some sources about the theory of the vortex formation at the tank outlet and vortex breaker design to prevent the vortex.

The tank is a 21 meter height and 92 m diameter crude oil tank.

Outlet pipe is 48".

There are some formulas which is related with froude number. I put a device at the outlet of the tank to decrease the froude number to prevent vortex formation.



Thanks in advance...

 

RE: VORTEX BREAKER

There was an article in Chemical Engineering, May 9, 1988 pages 108/109 on "Do-it-yourself" Vortex Breakers". It didn't have much theory but had some practical guidelines on pipe sizes and velocities, as well as some simple designs for the vortex breakers.

regards

I seem to remember seeing some design information in the GPSA Engineering book.  Unfortunately I don't have that book any more.
Maybe someone who has that book can chime in.

What section you you thinking? I can go look it up.

RE: VORTEX BREAKER

I didn't find anything specific in GPSA on a quick browse, but a couple of thoughts:

If you have Shell contacts, standard drawing 10.010 covers bottom outlet vortex breakers up to 24". This would extrapolate for 48" ND to a 72" circular plate (1.5ND) located 24" (0.5D) above the outlet on 16-20 radial baffle plates.   

Also NFPA 20 has a design for side outlet nozzles in the appendix.
