The thin film evaporator (TFE) is a unit operation used
primarily to concentrate a solute. There are many industrial
applications which use this theory - for example, when orange juice
concentrate is made, an evaporation technique is used to remove the
excess water.Purpose
The goal of this laboratory exercise is to study film evaporation and
heat exchange in a close clearance agitator evaporator.
Learning Objectives
The main learning objective of this laboratory exercise is to gain
experience in characterizing the behavior of a thin film evaporator. To
do this, one must examine such parameters as the overhead and bottoms
products at various feed rates and compositions, cooling water rates,
and steam pressures . These parameters should be calculated
theoretically using available computer programs and determined
experimentally from the thin film evaporator apparatus. |
