The effect of sulfolane on carbon dioxide(CO2) absorption and desorption by monoethanolamine(MEA) aqueous solution was measured by gas-liquid stirring rig and true heat flow calorimeter
including CO2 cyclic loading
absorption rate
heat of absorption and desorption. The experimental results show that sulfolane effect is significant for absorption rate
CO2 cyclic loading and CO2 desorption. In the condition of sulfolane addition
CO2 absorption rate into MEA solutions decreases and the decreasing amplitude increases with CO2 loading increase. Sulfolane can also accelerate desorption process and improve desorption level. Meanwhile
the heat duty
condensation duty and energy consumption are to some extent decreased. Under the condition of flue gas of coal-based power station and 20% sulfolane addition
the apparent CO2 absorption rate averagely decreases 10%
CO2 cyclic loading increases 24% and unit energy consumption for CO2 desorption decreases 18% in comparison with 20% MEA solution.
