Mass transfer coefficients of carbon dioxide in aqueous blends of monoethanolamine and glycerol using wetted-wall column

There is an urgent need for CO2 capture development because of the global warming crisis. Recently absorption by mixture monoethanolamine (MEA) and glycerol, as eco-friendly solvent, has been considered due to its promising performance low technical environmental impacts. However, more aspects this process, especially mass transfer coefficients, be studied further. In work, a bench-scale wetted-wall column was used find coefficients in aqueous blends MEA (25 wt%) glycerol (5–20 wt%). The experiments were performed nearly industrial conditions flue gas at atmospheric pressure three different temperatures (313, 323, 333 K). flow rate maintained around 0.17 ± 0.01 stdL/s, partial range 1–15 kPa. findings revealed that increasing 10 wt% improves overall (KG), adding up 20 decreases KG. gas-side resistance (1/kg) found negligible. Thus, primary liquid phase. It also solution with 25 (10G25M) had highest liquid-side coefficient (kg′) among other solutions. 10G25M showed comparable even better than solutions higher concentration literature. Compared industrial-grade, kg′ over two times 30 solution.
