ABSORPTION CO2 GAS USING MONOETHANOLAMINE
Abstract
The air on an area of solid industry, having a level pollution that high . it is much
caused the process of combustion done by most of the industry , whereby on the process of
combustion will be produced a gas of dioxide carbon ( CO2 ) that edangers . Hence , required
a method to depress figures pollution resulting from the womb overgrowth CO2 in the air the ,
one of them is with the process of absorption .CO2 absorption process using
monoethanolamine (MEA) performed in a packed column absorber aims to determine the price
of overall volumetric mass transfer coefficient of the gas phase to the variable operation and
know the value of the interfacial area per unit volume packing (a) of the price of the coefficient
volumetric mass transfer. CO2 gas flowing to the packed column using MEA as a solvent. The
results are overall volumetric mass transfer coefficient of the gas phase, KGa the greater the
rate of CO2 gas at a constant flow rate of MEA and its getting bigger. Likewise, under the same
conditions, the price of interfacial area per unit volume will increase packing. But at a
constant rate of MEA with greater gas flow rate of CO2 will cause the overall mass transfer
coefficient of the gas phase, KGa decreases. While at the greater concentration of MEA
solution will cause the KGa is increasing. The interfacial area per unit volume packing is not
affected by changes in gas flow rate and concentration of MEA.
Key words: Absorption of CO2,, Monoethanolamine, overall volumetric mass transfer
