Question
Transcribed Image Text:The use of a continuous atmospheric gravity separator which is also known as decanter is widely
applied in separating immiscible liquids that are having distinct densitie s. Figure 1 shows a
decenter that separates two immiscible liquids (Liquid A and B) in which liquid B having higher
density than liquid A. The feed mixture enters the unit at one end of the separating vessel and
flows slowly to the other end which e ventually cause the mixture to separate itself into two distinct
la yers. Liquid A and B flow out at the overflow lines to the respective collection tank which are
open to atmosphere. For a properly designed decanter and assuming that the frictional resis tance
to the flow of the liquid is essentially negligible, analyze the effect of the density of both liquids to
the vertical height of the liquid B (hgi & hg2).
Subsequently show that the vertical he ight of the liquid interface (hai) depends on the vertical
difference of both overflow lines.
Elaborate the purpose of having the overflow line of liquid B to be elevated at certain height, hr2.
