Abstract
Wire mesh entrainment separators were installed in a vertical cylindrical column at varying angles from the horizontal. With a fixed liquid loading, air flow rates were varied in order to determine the maximum capacity of the mist eliminator for any given angle of installation. Mist eliminators studied were 4" thick and constructed of 0. 011" diameter Type 304 stainless steel wire with a density of 12 lbs. per cubic foot and 5 lbs. per cubic foot.
For normal installations of mist eliminators in the horizontal plane, the following equation is used to determine maximum allowable design capacity:
V = K √(DL – DV/DV) (Perry, Chemical Engineers' Handbook Third Edition, p. 597
Where:
V = maximum design velocity in feet per second.
K = a constant for the system.
DL = the density of the liquid phase in pounds per cubic foot.
DV = the density of the gas phase in pounds per cubic foot.
This thesis developed values for K to be used in the above equation when mesh pads were installed at angles other than horizontal. The following expressions for K, when used in the above equation, correlate the values for maximum possible air velocity with angle at which the pad is installed.
K= 0. 290 plus 0. 308 Sine 0 (For 12 pound mesh)
K= 0. 378 plus 0. 308 Sine 0 (For 5 pound mesh)
(Where is the angle between the horizontal plane and the bottom surface of the mist eliminator pad. )
The maximum air velocity is established as that velocity beyond which re-entrainment occurs above the entrainment separator.
