1. Objectives

Chemical engineering

t
hermodynamics is a branch of chemical engineering. I
t i
s
the

base course of

uni
t operations, reaction engineering curriculum
.

I
t
provide
s

the
necessary fluid thermodynamic properties and phase equilibrium data
in
the
process
of

the chemical analysis, chemical reactors, separation equipment and
process control design studies, direct
ly

service
for industrial production. The
main
task
of this
course is to solve two major problems, namely the process of rational
use of energy issues and the direction
and
limit
ations

of chemical reactions
.
