Carbon dioxide (CO2) bubbles are common during carbon capture, utilization, and storage (CCUS) processes have many impacts on water conservancy machinery, metallurgy, the chemical industry. To explore dynamic characteristics of CO2 in different liquids CCUS, motion mechanism was integrated, effects liquid external conditions were classified summarized. At same time, research progress numerical simulation bubble dynamics is reviewed. Therefore, approaches methods that can be further explored theoretical analysis, experimental research, proposed, which provide reference guidance for engineering practice, especially CCUS technologies.

Effect of Temperature and Gas Flow Rate on CO₂ Capture

European Journal of Sustainable Development Research, Год журнала: 2022, Номер 6(2), С. em0181 - em0181

In this study, the removal of carbon dioxide (CO2) that has a huge contribution to global warming from gas emissions was performed using absorption method. Effect operational parameters such as temperature and flow rate on capacity (g CO2/kg solvent mol CO2/mol MEA) investigated in bubble column reactor with semi-batch operation. The monoethanolamine (MEA) used determined at different rates (2.5 5 L/min) temperatures (25-35-45 oC). Because capacities 74.71 g CO2 / kg MEA 0.51 were obtained L min rate, 25oC 20% concentration. increases decreases increases. it can be concluded capture into solution successfully achieved high capacity.

Separation and Purification Technology, Год журнала: 2024, Номер 341, С. 126900 - 126900

Опубликована: Фев. 24, 2024

Taylor bubble dynamic characteristics of CO2 chemical absorption into MEA aqueous solution in a vertical minichannel were systematically investigated this study. The generation, movement, and shrinkage bubbles the visualized monitored using high-speed camera, their behaviors characterized by image analysis method. effects gas liquid Re numbers absorbent concentration on two-phase flow patterns, generation frequency, initial length, length decrease rate, velocity examined analyzed. Results showed that reaction-enhanced mass transfer hindered cap penetration main channel, alleviated neck thinning, both inhibiting generation. A new Damköhler number (Da)-based correlation has been proposed to predict showing good prediction accuracy for experimental data literature different absorbents. also before formation sphere at end absorption, an approximate linear relationship exists between rate velocity, with slop decided reaction could be Da number. Finally, simple model developed determine effective channel given operating condition, providing design guidelines microchannel-based miniaturized absorbers.
