Biogas upgrading process using MDEA/AMP & MEA/AMP blended amines |
| 초록 |
This paper reports the newly measured experimental data for CO2 solubility in a blended aqueous solution of and methyldiethanolamine (MDEA) / 2-amino-2-methyl propanol amine (AMP) and monoethanol amine (MEA) / AMP at different amine mixing ratios (Amine1:Amine2:H2O = 9:21:70, 15:15:70, and 21:9:70 wt%) and working temperatures (323.15-383.15 K). Aspen plus solubility data was regress to experimental data through aspen plus and MATLAB interworking. The importance of electrolyte pair parameters in e-NRTL was identified through gross sensitivity analysis by Monte Carlo simulation. For computational efficiency, only a minimum number of parameters were used in the simulation. Using the above mentioned model, the partial pressures of CO2 in the gas phase, mole fractions of all components in the liquid phase, cyclic capacities of CO2 according to the absorption/desorption temperature and the blending ratio of mixed amines were estimated. And biogas upgrading process was optimized by multi-objective optimization used Genetic algorithm. |
