本研究主旨在驗證氣膠於吸收塔內成長機構與藉由改變操作條件以移除氣膠微粒。在此研究中，模擬氣膠成長情形於二氧化碳捕獲吸收塔，以乙醇胺作為吸收溶劑，由Aspen Plus®吸收塔模擬可得到吸收塔內所需數據，再利用gPROMS進行氣膠微粒成長與乙醇胺排放量之計算，並利用實驗室級吸收塔驗證此模型。在模擬中可給予起始粒徑與微粒數目濃度，結果顯示當微粒數目提高時，氣膠的成長將被抑制，粒徑隨微粒數目濃度提高而變小，當微粒數目提高時，乙醇胺的排放量也隨之提升，大量的乙醇胺排放至大氣中，藉此推斷微粒數目濃度對於氣膠成長與乙醇胺的排放量有著極大的影響。

This study seeks to validate the aerosol growth models and establish a strategy to remove aerosol by changing specifications and adjusting operating conditions of amine scrubbers. In this study, aerosol growth in CO2 capture absorber using monoethanolamine(MEA) solution was simulated. Absorber profile is obtained from process modeling using Aspen Plus® and is input to gPROMS model for aerosol growth and amine emission calculation, the model was validated by the experiment of bench scale absorber. Given an initial water aerosol size and particle number concentration that is saturated with inlet flue gas content, the results show that the effect of aerosol particle number concentration is significant, the final size of the aerosol decreases as particle number concentration increases, and aerosol growth is inhibited with a very high particle number concentration. An amount of amine being carried out into the atmosphere and also increase with the initial aerosol number concentration.
