High-pressure phase equilibrium of the ternary system carbon dioxide + water + acetic acid at temperatures from 313 to 353 K

Screening and evaluation of a saline aquifer for CO2 storage: Central Bohemian Basin, Czech Republic

“…CO 2 could exist either as a separate phase or as an aqueous component. CO 2 solubility in water was based on literature data (Duan and Sun, 2003;Bamberger et al, 2004;Bando et al, 2004) and introduced into the simulation model in the form of equilibrium constants K w . Equilibrium constants are specified in STARS in the form of pressure, temperature and, if needed, composition of one of the components to calculate phase equilibrium (STARS, 2009).…”

Fractionation of a dilute acetic acid aqueous mixture in a continuous countercurrent packed column using supercritical CO2: Experiments and simulation of external extract reflux

“…These two kinds of behaviors are well accounted for by the selected thermodynamic model as it is seen on Fig. 3 for two sets of conditions described in the literature [25,33]. On the pressure and temperature range considered here, Type I and Type II are very close to each other because of the very narrow immiscibility zone between solute and solvent for Type II and the tie line directions for Type I contrarily, for example, to the CO 2 -ethanol-water system described by Brunner et al [23].…”

“…Experimental data for carbon dioxide-acetic acid-water high pressure systems are available in the literature [33]. In order to perform the simulation of the process, a thermodynamic model has been chosen to represent the behavior of the ternary system.…”

Phase equilibria in chemical reactive fluid mixtures

“…The research covered, e.g., the dimerisation of carboxylic acids [1][2][3][4][5], the association of alcohols in organic liquids [6][7][8], the solubility of sour gases in aqueous solutions of ammonia [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] or amines (as well as amine blends) [24][25][26][27][28][29][30][31][32][33][34][35][36][37], the phase equilibrium in aqueous and methanolic solutions of formaldehyde [38][39][40][41][42][43][44][45][46][47][48][49][50]…”
