Saiptech's Side to Side Baffle and Disc and Donut Trays


For systems where extremely high capacity, fouling and pressure drop are major concerns, side to side baffle and disc and donut trays may be a suitable choice. For both of these tray types, liquid and vapor
contacting is accomplished by vapor passing through a curtain of liquid falling from one
tray to the next tray below. The tray decks are flat or inclined plates that block 40-60
percent of the cross sectional tower area. In addition to the sloped configuration for the tray decks, other design variations may include inlet or outlet weirs, uniform or partial perforated design. Typical side to side trays are depicted at right. Typical disc and donut trays are depicted below.

Comparison of Common Conventional Tray
TRAY TYPE  BUBBLE CAP  DUALFLOW  SIEVE  VALVE 
Capacity  Moderate  Very High  High  High to very high 
Pressure Drop High  Low to Moderate Low to Moderate Moderate.Older designs were somewhat higher.Recent designs same as sieve trays. 
Efficiency  Moderate (0.6 - 0.8) Lower compared to others (0.5 - 0.7) High (0.7 - 0.9) High (0.7 - 0.9)
Turndown  Very high Can handle very Can handle very low liquid rates  Low. Not suitable for suitable for varying loads  Approx. 2:1. Unsuitable for Unsuitable for varying loads operation  Approx. 3-5:1 Higher turndown Higher turndown designs can be provided on request. 
Maintenance  Relatively high  Low  Low  Low to moderate 
Fouling Tendency  High. Tends to accummulate solid particles Extremely low. Best choice for Severe fouling Low  Low to moderate 
Main Application  Very low flow conditions where leakage needs to be minimized Capacity revamps where efficiensy and turndown not critical high fouling and corrosive servies Most columns where trundown not important Most Columns services where turndown important
Cost  High -approx 2~3 times that for sieve trays Low  Low  Marginally higher than sieve trays
