What is a baffle tray
(OP)
Dear all,
Is there any one familiar with the tower tray? What is the baffle tray? And what is the difference between baffle tray and shower deck tray?
Is there anyone could explain to me? I appreciate so much

RE: What is a baffle tray
It is unusual to find these trays used in distillation or absorption duties. They are apparently sometimes employed as the stripper column in a fermentation ethanol plant where there are about 10% solids in the liquor.
The more common application of these trays (AFAIK) is in direct contact condensers (aka barometric condensers). But even in this duty they are rare and "rain trays" are more commonly used.

Baffle trays or so-called shed decks are usually employed in wash section of FCC main fractionator and catalyst strippers. The only advantage of these trays is they are impossible to plug while still providing the basic purpose of washing flash zone vapors from entrained liquid, and also providing smooth flow of fluidized catalyst particles. It is very roboust and not so efficient design, nowadays almost completely abandoned except in few specific applications.

RE: What is a baffle tray
Baffle trays and disc & donut trays are particularly
well suited to heavy fouling systems due to their extremely
high open area. Typical applications include heavy oil
refining and petrochemical heat transfer services having a
high solid and/or petroleum coke content.
Baffle trays are trays of low fouling potential, with low
efficiency. They have open areas approaching 50%
where a high efficiency tray will have an open area of less
than 15%.
Three major types of baffle trays are
1. Shed Decks
2. Side to Side Trays
3. Disk and Donut

Could you tell me where I could find that article?
I have searched by google.But no matching result.
RE: What is a baffle tray
Could you tell me what is the difference for the side-to-side pan and shed deck? Is it because that shed deck has some holes on the deck? If so, what is the common size of the hole?
Thanks a lot!

“Side-to-side trays are trays that allow the liquid to splash from side to side. The decks can be sloped. Fouling potential of this tray is low, as with efficiency”
