Abstract:
Evaporation is the removal of solvent from solution as vapor. Multiple effect
evaporators are important in unit operation process for industry. For instance, they
are widely used in the production of raw sugar from cane sugar. The main
objective of this work is to develop program in MATLAB software for the design
of multiple effect evaporators system for different operating conditions in forward
feed used in Asalaya sugar factory. In this design a short tube vertical evaporator,
Calandria type has been used. In this study, design of selection of type of
evaporator using some parameters is presented for multiple effect evaporator
system.This study describes a steady state model of multiple effect evaporators for
simulation purpose. The model includes overall as well as component heat and
mass balance equations, and heat transfer coefficient, and area calculation for all
the effects.As result of calculations, it has been found that about 5.54 of steam
economy and the efficiency of multiple effect evaporators equal about 81.94%.
