dc.description.abstractDuring the process of CO2 capture using amine solvents, there is a certain amount of solvent loss. Amine vapourization has been categorized under such solvent losses. A systematic approach is required to determine such losses. This study aims at quantifying amine vapourization loss for current operating plant conditions by an in-house process model using excel. Experimental data was generated for a binary solution of monoethanolamine (MEA) + water (H2O) in a range of 1-7 kmol/m3 at 80oC using a Swietoslawski Ebulliometer. At this low concentration range of MEA, the correlation between activity coefficient and the concentration of MEA obtained was scattered. An empirical equation using Raoult’s Law was developed as a function of the activity coefficient, concentration of amine, and temperature. The regressed data, for activity coefficient increased as a function of amine concentration, and saturated vapour pressure increased as a function of temperature. The amine loss from the top of the absorber corresponding to the amine plant conditions was studied using the derived empirical regressed equation. This study was based on the assumption that no cooling equipment being installed on the top of the absorber to reduce the escape of amine solvent with the treated gas. The parametric effects on amine loss in the gas absorption column were evaluated. The behaviour of lean CO2 loading, feed gas temperature, concentration of amine, and the scrubbing process showed to have an effect on the loss due to vapourization.en_US
