Experimental Study and Modeling of Mass Transfer Flux of CO2 Absorption with Amine Solution in Bubble Column |
|
| چکیده انگلیسی مقاله |
In this study, the effective parameters in mass transfer in the process of gas absorption in the bubble column by amine solvents have been investigated. Also, the aim of this study is to present a general and accurate correlation with the least simplifying assumptions to calculate the mass transfer flux of gas phase to liquid phase components in three electrolyte systems MDEA-Pz, MEA-Pz, and MEA-MDEA. The effect of parameters on mass transfer such as retention time, apparent gas velocity, liquid phase properties, operating conditions, type of distributor, and bubble characteristics was analyzed. Effective parameters were expressed to achieve functional correlations using dimensionless numbers by using the pi-Buckingham theorem. The correlation coefficients for MDEA-Pz, MEA-Pz, and MDEA-MEA were obtained at 0.951, 0.981, and 0.924, respectively. The mean relative error obtained from predicting the mass transfer flux correlation for all three MDEA-Pz, MEA-Pz, and MDEA-MEA amine combination systems was 3.6, 4.5, and 4.8%, respectively. The results showed that the proposed correlations for mass transfer flux compared to other correlations have high accuracy. |
