NUMERICAL SIMULATION OF CO2 ABSORPTION BY AMP SOLUTION IN STRUCTURED PACKING WITH DIFFERENT PARAMETER CONDITION

ABSTRACT
The FLUENT software is utilized in this research to simulate the CO2 absorption process by 2-amino-2-methyl-1-propyl (AMP) alcohol through numerical simulation. A mathematical model is established to represent the mass transfer process between the AMP alcohol solution and CO2. Various operating parameters, such as the molar fraction of the solution, gas mass fraction, pressure, and gas-flow velocity, are investigated to calculate the absorption efficiency of CO2 under different conditions. The distribution of the product reveals that the AMP alcohol carbamate product more readily infiltrates the surface of the unit model when the gas phase velocity is relatively low. In contrast, the product AMP alcohol carbamate tends to accumulate in the upper half of the unit model when the gas phase velocity is relatively high. Sixteen simulation conditions are summarized to determine the optimal parameters. These optimal parameters include a AMP alcohol molar fraction of 0.4, atmospheric pressure, a flue gas-flow velocity of 0.0737 m/s, and a CO2 mass fraction of 0.12. This research serves as a valuable reference for engineering applications related to CO2 absorption using AMP alcohol solutions, providing essential technical support in the fight against climate change.
