“…At higher loadings, the two data sets differ substantially, except for the highest loadings (about 1.1) when the data tend to agree again. Fogg and Young 1 also mentioned that the first two sets of measurements 106,107 are consistent with each other in the pressure range over which measurements overlap, from (4 to 180) kPa (up to about 0.75 mol of H 2 S/mol of DGA).…”

“…The solubility of hydrogen sulfide in aqueous solutions of DGA was investigated by Martin et al 106 in w(DGA) ) 60 % at (323 and 373) K, by Dingman et al 107 in w(DGA) ) 65 % from (311 to 355) K, and by Maddox et al 85 in w(DGA) ) (40 and 60) % from (313 to 353) K. For an aqueous solution of w(DGA) ) 60 % and 323 K, there is a reasonable agreement between data measured by Maddox et al 85 and those by Martin et al 106 only at loadings up to about 0.71 mol of H 2 S/mol of DGA. At higher loadings, the two data sets differ substantially, except for the highest loadings (about 1.1) when the data tend to agree again.…”

The solubility of the total reduced sulfurs, which include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3), and dimethyl disulfide (CH3S2CH3), is of great interest in various applications in the chemical, oil, and gas industries and in environmental protection as well. They can occur naturally in the environment and can also be present in numerous industrial gaseous streams (petroleum, natural gas, some chemical industries like the pulp and paper industry). The aim of this review is to update different aspects concerning the solubility data of these compounds in various liquids, which are essential for the design and operation of absorption scrubbing equipment and/or of interest in many technical areas (e.g., the petroleum and natural gas industry). The review deals with the compound's characterization in direct connection with their source and a survey of relevant existing experimental data including (i) all data concerning the solubility of methyl mercaptan, dimethyl sulfide, and dimethyl disulfide published generally before January 2006 as well as (ii) data concerning the solubility of hydrogen sulfide published generally after January 1987. The liquids include water, aqueous electrolyte solutions, nonaqueous solvents, and alkanolamines. Both pure compounds and mixtures are considered.

“…In this research fugacity coefficient was calculated with use of Redlich-Kwong EOS [22] , activity coefficient was determined with use of electrolyte Non Random Two Liquid model, and coefficients for Henry constant of 2-(Ethylamino) ethanol, were based on diglycolamine (DGA) from [23].…”

“…However, due to the limited number of data on EAE, it was decided to follow Austgen [32] concept, where the dielectric constants for pure diglycolamine (DGA) was set equal to dielectric constants for diethanolamine (DEA), due to missing data. Therefore coefficients for Henry's constants [23], the dielectric constants [32], equilibrium [14] and kinetic constants [16] were based on DGA [15]. Parameters for CO 2 and H 2 O were acquired from ASPEN Plus ® databanks (APV80.PURE27 and APV80.Binary).…”

Carbon dioxide solubility was studied in 2.5 mass % and 5 mass % aqueous 2 (Ethylamino)ethanol (EAE; CAS 110-73-6) solution, an interesting secondary amine prepared mainly from renewable resources, at high loading rates, at three temperature ranges (293.00K, 313.15 K, 333.15 K), and in pressure range from 289 to 1011 kPa. In addition to that, heat capacity (cp) was measured of examined solution, allowing determination of temperature dependent coefficients of ideal gas heat capacity equation. Afterwards, the electrolyte Non Random Two-Liquid model's parameters were determined to represent the thermodynamic behaviour of the CO 2 -EAE -H 2 O system with use of ASPEN® Plus V8.0 simulation software, indicating a good correlation between experimental and simulation results. As a consequence, model based calculation of the carbon dioxide capture with use of 2- (Ethylamino)

Information on acid gas solubility in solvents utilized is needed for the design of gas plants. A mathematical model for the prediction of equilibrium solubility of COz and H2S in aqueous 2-amino-2-(ethoxy)ethanol (DGA) solutions is presented. The equilibrium constants, K , and Kz. representing a simple proton transfer reaction and the carbamate formation reaction, respectively, were found to be functions of temperature and free acid gas concentration. In addition, K?, was affected by DGA concentration as well. Model predictions agree favourably with experimental data.Des donnkes sur la solubilitk des gaz acides dans les solvants sont nkcessaires pour la conception des usines gaz. On prksente un modde mathkmatique pour la prkdiction de la solubilitk d'kquilibre du COz et du H, dans des solutions aqueuses de 2-amino-2(kthoxy)kthanol (DGA). On a trouvk que les constantes d'kquilibre, K , et K 2 , reprksentant une rkaction de transfert de protons simples et une rkaction de formation de carbamate, respectivement, ktaient des fonctions de la tempkrature et de la concentration de gaz acide libre.
