Settings of the radfrac module during simulated CO2 absorption

When using the radfrac module to simulate CO2 absorption, the liquid-phase resistance discretize film is chosen because it can represent the mass transfer resistance at the gas-liquid interface more accurately. Regarding the selection of film reactions, it is usually necessary to decide whether to activate them based on experimental data or detailed chemical reaction mechanisms. If the absorption process involves relatively fast chemical reactions that occur primarily within the liquid film near the gas-liquid interface, then choosing film reactions is appropriate. As for the transfer condition factor and reaction condition factor in the global settings of the rate mode, these two parameters are typically set to 1 by default, representing standard conditions. The transfer condition factor adjusts the mass transfer coefficient at the interface. If you have reason to believe that the transfer coefficient deviates from the standard value under certain specific conditions (such as extreme temperature or pressure conditions), this factor can be adjusted. The reaction condition factor is used to adjust the reaction rate constant; if the actual operating conditions (such as temperature and pressure) differ from the standard conditions, it may be necessary to adjust this factor in order to accurately reflect the reaction rate. In short, whether to change these factors depends on your specific simulation conditions and experimental data. If there is insufficient data support, it is recommended to use default values for preliminary simulations first, and then make adjustments based on the results. .
