Abstract
Absorpsi karbon dioksida (CO2) merupakan hal yang penting dalam dunia industri. Dalam industri, khususnya industri petrokimia, minyak, dan gas alam pada prosesnya diperlukan pemisahan gas CO2 dimana gas ini merupakan gas yang korosif (acid gas). Maka penting dilakukan proses pemisahan CO2 dari aliran gas, salah satu caranya adalah absorpsi reaktif menggunakan pelarut methyldiethanolamine (MDEA) berpromotor. Maka, dilakukan penelitian ini untuk memperoleh data kinetika reaksi absorpsi CO2 dalam larutan MDEA dengan menggunakan promotor Arginine dan L-Glutamic Acid. Arginine dan L-Glutamic Acid dipilih karena merupakan senyawa asam amino yang reaktif, sehingga dapat mempercepat laju reaksi MDEA. Metode yang digunakan adalah absorpsi menggunakan peralatan wetted wall column skala laboratorium pada tekanan 1 atm. Dari penelitian ini didapatkan informasi mengenai data kinetika reaksi sebagai upaya untuk mengoptimalkan proses pemisahan CO2 di dunia industri. Hasil yang didapat dari penelitian ini menunjukkan peningkatan temperatur operasi meningkatkan laju absorpsi CO2. Semakin tinggi temperatur operasi maka laju absorpsi akan semakin meningkat. Selain itu, penambahan promotor kedalam larutan MDEA dapat meningkatkan laju absorpsi CO2 secara signifikan. Semakin banyak penambahan promotor maka laju absorpsi akan semakin meningkat. Hasil tersebut menunjukkan bahwa penambahan Arginine dan L-Glutamic Acid sebagai promotor dapat menambah laju absorpsi CO2 pada larutan MDEA dan mampu menutupi kelemahan larutan MDEA. Maka, didapatkan persamaan konstanta laju reaksi absorpsi CO2 dari penelitian ini adalah kArginine = 4.55 x 1015 exp (-7647.202/T) (sistem MDEA-Arginine-L-Glutamic Acid), kL-Glutamic Acid = 6.92 x 1014 exp (-7110.423/T) (sistem MDEA-Arginine-L-Glutamic Acid), kArginine’ = 1.78 x 1014 exp (-6629.138/T) (sistem MDEA-Arginine), kL-Glutamic Acid’ = 1.09 x 1013 exp (-5857.554/T) (sistem MDEA-L-Glutamic Acid), dan kMDEA = 1.14 x 1016 exp (-9567.053/T) (sistem MDEA) (m3/kmol.det).
=================================================================
Carbon dioxide (CO
2
) absorption is the important part in
industrial
.. Particularly in
petrochemical, oil and gas industries, as
the most contributed in CO
2
releasing, need to remove the CO
2
gas
since it was the acid and corrosive gas.
Since the importance of
CO
2
removal from gas stream, the use of methyldiethanolamine
(MDEA) with promotor
i
s chosen as the way for reactive
absorption.
Thus the experiment proposed to find the CO
2
absorption kinetic velocity in MDEA solution using
Arginine
and
L
-
Glutamic Acid
promotor.
Arginine
and
L
-
Glutamic Acid
are
chosen since they are
reactive amino acid t
hus rising the CO
2
absorption kinetic velocity in MDEA solution.
The chosen method
for this experiment was absorption using wetted Wall Column in a
laboratorium scale with 1 atm
pressure. The purpose of this
experiment was to find out the reaction kinetic data in order to
optimize the CO
2
separation process in industrial world. The result
from this experiment shows the increasing of operating
temperature impact on the increasing
of CO
2
absorption kinetic
velocity. The addition of promotor in MDEA solution will
significantly increase the CO
2
absorption velocity. CO
2
absorption
velocity
is
getting fast
er
along with
more pro
motor
addition
in
solution
. The result also shows the additi
on of
Arginine
and
L
-
iv
Glutamic Acid
mixture as promotor will increase the CO
2
absorption velocity in MDEA solution and adequate to cover the
weakness of MDEA absorption velocity. From the experiment and
data calculation, the constants equation of CO
