Characterization of Loading Rate of CO2 with Mono Ethanol Amine Continuous Reactor Experimentation & Titrimetric CO2 Loading Evaluation

Abstract

This study delves into leveraging a continuous reactor experiment setup for CO2 Capture using Mono Ethanol Amine (MEA). A series of experiments were conducted utilizing various concentrations of MEA from 10% to 30% wt/wt under controlled conditions to determine their CO2 loading rates. The continuous reactor system offered insights into the kinetics and equilibrium behaviours of the MEA-CO2 interaction. The CO2 loading with MEA solvents is estimated using a titrimetric method, the UOP 829-821 which consumes less resources for research in a laboratory setup. This enabled repetitive and reciprocal loading rate assessments of CO2 loading rate analysis with MEA solvents. The CO2 content in the experimented amine samples ranged from 0.13 to 0.45 mol CO2 / mol MEA while varying the CO2 concentration between 10% to 20% and MEA Concentration from 10% to 30% for a range of absorption time periods. The CO2 loading performance showed only a marginal performance improvement was found between 20% and 30% MEA concentration. The results of this study can help pave pathways for more efficient MEA based CO2 Capture Technologies.
