SIMULASI PEMISAHAN SISTEM BINER DENGAN DISTILASI BATCH SEDERHANA
Abstract: A simulation on
separating binary system has been studied to investigate the temperature and
liquid compositions profiles in the bottom changing with time. By having temperature
and liquid compositions profiles in the bottom, one can find whether the binary
mixture forms azeotropes or zeotropes mixtures. Antoine equation has used to
calculate saturated vapour pressure at atmospheric pressure. The activity coefficient
was calculated using UNIQUAC. Forward finite-difference was used to get the
calculated value of the bottom still composition at a given time starting from
a given initial composition of binary system.
Several initial values
of the composition
binary system had
been chosen to
complete liquid compositions in
the bottom. The results showed that the temperature profiles of
acetone-n-butanol and ethanol-n-butanol
binary system have
differences characteristic from
acetone-ethanol binary system. Those can be seen from activity
coefficient profile. The results showed that the binary system formed zeotropes
mixture, without having any azeotropes mixtures of its components. The
results simulation on separation
binary system has been validated
with hydrocarbon binary
system benzene-toluene mixture.
