“…The excess molar heat capacities, C P E , of the aqueous binary solutions were obtained. By definition C P E is the difference between the heat capacity of the solution and the summation of the pure components contribution 1 1 , ( mol )…”

“…However, this limits the CO 2 loading to 0.5-1.0 mol of CO 2 per mol of amine, and leads to high energy requirement during amine regeneration. On the other hand, tertiary amines like MDEA can theoretically achieve high CO 2 loading, which is due to the formation of bicarbonates (instead of carbamates), but their low CO 2 absorption rate limits their use [1].…”

Abstract-In this work, we reported the molar heat capacities, C P , of aqueous solutions of the sterically hindered amines 2-amino-2-methyl-1, 3-propanediol (AMPD), and its aqueous ternaries containing piperazine (PZ) or lithium bromide (LiBr). Measurements were performed in the temperature range 303.15 K to 353.15 K and atmospheric pressure by heat flow differential scanning calorimetry. The excess molar heat capacities, C P E , of the binary solutions were determined, and the data were represented as function of temperature and composition using a RedlichKister-type equation. The C P of the ternary mixtures was correlated with temperature and amine concentration using the Sohnel and Novotny equation. Results showed that the calculated data agree very well with experimental C P values at average absolute deviation values of less than 0.2%. Index Terms-2-amino-2-methyl-1, 3-propanediol, molar heat capacity, redlichkister equation, sohnel and novotny equation.

“…The CO 2 absorption process using aqueous amine solutions is a well-established separation technique in chemical industries such as natural gas sweetening, coal gasification and manufacturing of ammonia. Aqueous amine solution removes acidic gases mainly such as CO 2 and mercaptans by forming a salt in order to achieve the required product quality and to minimize operational difficulties, which may occur in downstream processes [1].…”

Abstract-A mathematical model simulating the corrosion behavior of carbon steel in aqueous amine-CO 2 environment was developed and used to analyze the corrosion phenomena in CO 2 loaded amine solutions. A mechanistic corrosion model is applied to identify the most important agents responsible for the corrosion behavior of carbon steel. The model incorporates an equilibrium model based on an activity coefficient approach according to Debye-Huckel theory and mixed potential theory to simulate the concentration of chemical species and polarization behavior taking place at a metal-solution interface in a DEA-CO 2 -H 2 O system. Simulated anodic and cathodic polarization curves were established on the basis of the calculated species concentration to represent the hypothetical oxidation and reduction behavior which were compared to the experimental curves to come out with the best fit revealing the most important corroding agents.Index Terms-Corrosion model, diethanolamine, carbon dioxide, equilibrium model, mixed potential theory, polarization curve.
