“…Notable published literature (Fürst and Renon 1993, Orbey and Sandler 1995, Kontogeorgis et al 1996, Kontogeorgis and Coutsikos 2012 discussed the incorporation of various mixing rules and association equations in electrolyte and simple EoS followed by their thermodynamic justification. On the contrary, Polishuk et al (2002) gave a precise critique of excess Gibbs energy-based mixing rules. These authors cogently scrutinized their inconsequential "localized" fitting and shortcomings in attractive term of G E -based mixing rules.…”

AbstractThe knowledge of vapour-liquid equilibrium (VLE) and thermodynamic properties plays a pivotal role in the process development of absorption systems for acid gas capture in precombustion and postcombustion streams. A large number of thermodynamic modelling approaches for acid gas absorption in aqueous alkanolamine solutions are published in the literature. However, the reviews of these modelling techniques are limited and scattered. Moreover, poor guidelines exist for the selection of an appropriate modelling approach for the VLE prediction of the aforementioned system. Therefore, the current study presents a concise classification and review of classical thermodynamic models for acid gas absorption in aqueous alkanolamine solutions since their inception. The article systematically details the chronological development and highlights the major capabilities and limitations of classical thermodynamic approaches, namely, semiempirical models, activity coefficient models, and equation of state (and equation of state/excess Gibbs energy) models. A graphical comparison of VLE prediction by each classical approach is presented to form a general guideline in the selection of a suitable approach for process development studies. The review precisely discusses the issues, challenges, and future prospects of each classical thermodynamic approach in the context of application, complexity, and development.

“…Equations (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) show the flash calculation procedure for the Sanchez-Lacombe equation of state. When a fluid undergoes a reduction in pressure at constant temperature, from a pressure equal to or greater than its bubble point pressure to a pressure below the bubble point pressure, it will "flash" or produce a twophase system of vapour and liquid in equilibrium.…”

Prediction of Sanchez‐Lacombe equation of state characteristic parameters for plus fractions

2015

View full text Add to dashboard Cite

Sanchez‐Lacombe is one of the main polymeric equations of state that is used to predict thermodynamic properties of polymer solutions. Due to the similarity of the physical behaviour of polymer solutions and black oil, Sanchez‐Lacombe is also recommended to predict the liquid density of hydrocarbon fluids. In conventional thermodynamic equations of state, each component of the fluid is specified with some characteristic parameters such as the acentric factor, critical temperature, and critical pressure. Similarly, in the Sanchez‐Lacombe equation of state each component has some characteristic parameters which are obtained for pure components. Since there are no correlations for plus fractions (unknown fractions), the aim of this study is to present empirical correlations to predict the characteristic parameters of plus fractions based on experimental data. These empirical correlations are then used so that the Sanchez‐Lacombe equation of state can be applied to determine the liquid phase density of hydrocarbon fluids.
