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 2 absorp tion kinetic velocity result were k Arginine = 4.55 x 10 15 exp ( - 7647.202/T) (sistem MDEA - Arginine - L - Glutamic Acid ), k L - Glutamic Acid = 6.92 x 10 14 exp ( - 7110.423/T) (sistem MDEA - Arginine - L - Glutamic Acid ), k Arginine ’ = 1.78 x 10 14 exp ( - 6629.138/T) (sistem MDEA - Arginine ), k L - Glutamic Acid ’ = 1.09 x 10 13 exp ( - 5857.554/T) (sistem MDEA - L - Glutamic Acid ), dan k MDEA = 1.14 x 10 16 exp ( - 9567.053/T) (sistem MDEA) (m 3 /kmol. det).
