Abstract

Penelitian ini bertujuan untuk mencari korelasi koefisien perpindahan massa pada proses absorpsi gas C02 kedalam larutan K2C03 di dalam packed column dengan menggunakan packing tipe raschig rings dari bahan /ogam alumunium. Penelitian ini dilakukan dengan menggunakan column berdiameter I 0 em dan tinggi 200 em dari bahan fiberglass. Sistem yang digunakan adalah gas C02 - larutan K2C03 yang dikontakkan secara counter current. Variabel yang digunakan dalam penelitian ini adalah laju alir larutan K2C03 dengan cara mengatur valve sehingga manometer liquid menunjukkan 1'1h sebesar 0,5 em; I em; I,5 em; 2 em; 2,5 em; 3 em; 3,5 em dan 4 em pada laju alir gas C02 konstan sebesar 299,065 cm3 / s dan viscositas larutan K2C03 dengan cara menambahkan CMC dengan konsentrasi 0%; 0,05%; 0,1%; O,I5% dan 0,2%. Dari hasil penelitian terlihat bahwa semakin besar /aju alir larutan K2C03, koefisien perpindahan massa juga semakin besar. Penambahan surfaktan (CMC) menyebabkan kenaikan viscositas larutan sehingga nilai koefisien perpindahan massa menjadi turun. Penelitian ini menghasilkan korelasi empiris untuk koefisien perpindahan massa sebagai berikut: ~~ =36,620{(VL:Dr7955 (p~ABr~]

This study aims to find the correlation of mass transfer coefficient in the process of absorption of CO2 gas into K2CO3 solution in a packed column using raschig rings type packing made of aluminum / metal material. This study was conducted using a column with a diameter of I 0 em and a height of 200 em made of fiberglass. The system used is CO2 gas - K2CO3 solution which is contacted countercurrently. The variables used in this study are the flow rate of K2CO3 solution by adjusting the valve so that the liquid manometer shows 1'1h of 0.5 em; I em; I,5 em; 2 em; 2.5 em; 3 em; 3.5 em and 4 em at a constant CO2 gas flow rate of 299.065 cm3 / s and the viscosity of the K2CO3 solution by adding CMC with a concentration of 0%; 0.05%; 0.1%; O,I5% and 0.2%. From the research results it can be seen that the greater the flow rate of K2C03 solution, the greater the mass transfer coefficient. The addition of surfactant (CMC) causes an increase in the viscosity of the solution so that the mass transfer coefficient value decreases. This study produces an empirical correlation for the mass transfer coefficient as follows: ~~ =36.620{(VL:Dr7955 (p~ABr~]
