Abstract

Karbon dioksida umumnya dipandang sebagai salah satu kontributor utama iklim perubahan itulah sebabnya menghilangkan karbon dioksida dari bidang industri kimia sangatlah penting hal penting untuk mengurangi masalah pemanasan global, sehingga kita perlu mengurangi CO2 emisi dengan menggunakan metode yang dioptimalkan. Penyerapan bahan kimia menggunakan larutan alkanolamin tersier merupakan salah satu keharusan metode penting yang telah diusulkan dan dipelajari untuk menghilangkan karbon dioksida, karena pelarut MDEA memiliki biaya rendah, kecenderungan korosif rendah, stabilitas tinggi, rendah viskositas, kecenderungan berbusa rendah, dan mudah terbakar rendah, namun memiliki laju reaksi rendah oleh karena itu menambahkan glisin sebagai promotor ke pelarut konvensional dan untuk meningkatkan laju reaksi, karena glisin adalah senyawa amina primer yang reaktif, apalagi glisin memiliki ketahanan terhadap temperatur tinggi sehingga tidak mudah terdegradasi dan cocok untuk aplikasi di industri. Tujuan utama dari penelitian ini adalah untuk menyediakan data kinetika reaksi CO2 penyerapan ke dalam glisin mempromosikan methyldiethanolamine (MDEA) dengan menggunakan skala laboratorium peralatan kolom dinding yang dibasahi pada tekanan atmosfer dengan suhu yang bervariasi 303,15 menjadi 328,15 dan konsentrasi glisin dari 1% menjadi 3% dan penyerapan karbon dioksida laju diukur dengan titrasi limbah cair Berdasarkan hasil penelitian ini, kami mengamati bahwa dengan meningkatkan suhu dan konsentrasi glisin, laju penyerapan karbon dioksida dalam larutan MDEA akan meningkat, Selain itu konstanta laju reaksi akan dipengaruhi oleh suhu dan konsentrasi promotor. Korelasi konstanta laju reaksi k glisin adalah: k glisin = 5.3409E + 13exp (-3251.9 / T) dengan energi aktivasi promotor glisin sebesar 27.0363 kJ / kmol. ============================================================================================ Carbon dioxide is commonly seen as one of the major contributors to climate change that is why removing carbon dioxide from the chemical industry field is very important things to mitigate the problem of global warming, so we need to reduce CO2 emissions by using the optimized method . The chemical absorption using tertiary alkanolamines solution one of must important method which have been proposed and studied for the removal of carbon dioxide, because the MDEA solvent has low cost, low corrosive tendencies, high stability, low viscosity, low tendency to foam, and low flammability, however it has low reaction rate therefore added glycine as promoter to conventional solvents and to increase the rate of the reaction, because glycine is a primary amine compound which is reactive, moreover, glycine has resistance to high temperatures so it will not easy to degradable and suitable for application in industry. The main purpose of this study is to provide reaction kinetics data of CO2 absorption into glycine promoted methyldiethanolamine(MDEA) by using laboratory scale wetted wall column equipment at the atmospheric pressure by varying temperature from 303,15 to 328,15 and glycine concentration from 1%to 3% and the carbon dioxide absorption rate is measured by titration of liquid effluent Based on the result of this study, we observed that by increasing temperature and concentration of glycine ,the absorption rate of carbon dioxide in MDEA solution will increase, In addition the reaction rate constant will be affected by the temperature and the concentration of promoter. The correlation of reaction rate constant k glycine is: k glycine =5.3409E+13exp(-3251.9/T) with activation energy for glycine promoter is 27.0363 kJ/kmol.
