제목 Process optimization for MEA/DIPA mixed amines from the perspective of a Vapor-Liquid Equilibrium
초록 This paper reports the newly measured experimental data for CO2 solubility in a blended aqueous solution of Monoethanol amine (MEA) and Di-isopropanol amine (DIPA) at different amine mixing ratios (MEA:DIPA:H2O = 9:21:70, 15:15:70, and 21:9:70 wt %) and working temperatures (323.15, 343.15, 373.15 and 383.15 K). The successive substitution method [1] was used for calculating the mole fractions of all molecules (four molecules) and electrolytes (three cations and five anions) from the equilibrium, along with the material and charge balance equations (12 equations). The Novel shortcut method suggested by Lee et al. [2] was used to investigate regeneration energy of stripper for process optimization. Using the above mentioned thermodynamic models, the partial pressures of CO2 in the gas phase, mole fractions of all components in the liquid phase, heats of absorption, and cyclic capacities of CO2 according to the absorption/desorption temperature and the blending ratio of MEA/DIPA/H2O were estimated.
