The extension of the translated–consistent Peng–Robinson (tc-PR) equation state (EoS) to mixtures has been investigated. For this purpose, advanced EoS/aresE,? mixing rules are used combine tc-PR EoS with residual part an activity coefficient model chosen among Wilson, nonrandom two-liquid (NRTL), and universal quasi-chemical (UNIQUAC) models. performances three resulting versions compared agai...

CO2-foam injection is a promising technology for reducing gas mobility and increasing trapping within the swept region in deep brine aquifers. In this work, consistent thermodynamic model based on combination of Peng-Robinson equation state (PR EOS) components with an activity aqueous phase implemented to accurately describe complex phase-behavior CO2-brine system. The module combined represent...

Abstract: Reliable knowledge of the thermophysical properties of pure compounds and their mixtures in the whole composition and a wide temperature and pressure range is a vital prerequisite for computer-aided synthesis, design, and optimization of chemical processes. Knowledge of the various phase equilibria is most important for the development of thermal separation processes (but also for oth...

A composition stream from reservoir to the market has been obtained as a result of upstream, midstream and downstream retrograde gas-condensate models integration. Applications are composition, Peng-Robinson EOS has been chosen as a fluid package. Different production scenarios were observed to define development strategy for rich gas condensate production. VGD and C/V gas drive mechanisms have...

Cubic equations of state combined with excess Gibbs energy predictive models (like UNIFAC) and equations of state based on applied statistical mechanics are among the main alternatives for phase equilibria prediction involving polar substances in wide temperature and pressure ranges. In this work, the predictive performances of the PC-SAFT with association contribution and Peng-Robinson (PR) co...

−An industrial scale hexane process is designed for the implementation of a fully thermally coupled distillation column (FTCDC). A semi-rigorous material balance and Peng-Robinson equilibrium relation are utilized in the structural design. The operational design is conducted with a commercial design program, the HYSYS. The design outcome of the structural design indicates it to be comparable wi...

Due to the adverse effect of CO2 from fossil fuel combustion on the earth’s ecosystems, the most cost effective method for CO2 capture is an important area of research. The predominant process for CO2 capture currently employed by industry is chemical absorption in amine solutions. A dynamic model for the deabsorption process was developed with Monoethanolamine solution. Henry’s law was used fo...

The guidelines to constitute a database containing, for 1800 pure fluids, more than 300,000 pseudo-experimental vapor pressure, liquid density, enthalpy of vaporization, and heat capacity data are described. Such provides tool fair assessment the performances equations state correlate (or predict) properties components. In this paper, we use it assess performance four cubic (CEoSs): original So...

To cover the expected increased demand for natural gas, energy industry has to exploit sour gas reserves located around world. However, acid gases have be removed before produced from these fields could used. One of novel concepts in this field is utilization solid phase formation carbon dioxide and/or hydrogen sulfide. The main aim study develop an empirical correlation model based on Peng-Rob...
