 Abstract
The removal of carbon dioxide from flue gases of power plant to meet their discharge limits in atmosphere is usually achieved by chemical absorption in aqueous solutions of alkanolamines.
In this paper, a tertiary amine, (N-methyldiethanolamine- MDEA) was investigated for CO2 absorption process in a laboratory-scale packed column. The effects of initial CO2 concentration, the height of column packing and the liquid–gas (L0/G0) ratio on the absorption process and on CO2 recovery rate were analyzed.

 Rezumat
Eliminarea dioxidului de carbon din gazele de ardere ale termocentralelor, pentru a respecta limitele de evacuare în atmosferă, se realizează de obicei prin absorbție chimică în soluții apoase de alcanolamine.
În această lucrare, o amină terțiară, cum ar fi, metildietanolamina a fost investigată în procesul de absorbție a CO2 într-o coloană cu umplutură, la scară de laborator. Au fost analizate efectele concentraţiei de intrare a CO2, a înălțimii de umplutură a coloanei și a raportului gaz/ lichid (L0 / G0), raportul asupra procesului de absorbție și asupra gradului de recuperare a CO2.
