This study presents a comparative computational examination of different cubic equations state (EoS) on hydrate inhibition fluid systems involving real reservoir fluids. Two gas inhibitors (Monoethylene glycol – MEG and methanol) were considered alongside 4 EoS namely; Cubic-Plus-Association (CPA) coupled with Infochem mixing rules, Soave-Redlich-Kwong (SRK) the Huron-Vidal (HV) rule, Peng Robi...

Phase equilibrium experimental data for the CO2/glycerol system are reported in this paper. The measurements were performed using an in situ FT-IR method for temperatures ranging from 40 C to 200 C and pressures up to 35.0 MPa, allowing determination of the mutual solubility of both compounds. Concerning the CO2 rich phase, it was observed that the glycerol solubility in CO2 was extremely low (...

the equation of state soave-redlich-kwong (srk) and its modification (predictive srk or psrk) are applied to simulate multicomponet distillation, which separate main component of spearmint essential oil. the simulation model is based on bubble point method, and the wang-henke algorithm. spearmint essential oil is considered in the study and the original experimental data were obtained from pilo...

The present study investigates the use of different GE mixing rules in cubic equations of state for prediction of phase behavior of multicomponent hydrocarbon systems. To predict VLE data in multicomponent symmetric and asymmetric mixtures such as systems that contain light gases (nitrogen, carbon dioxide, etc.) and heavy hydrocarbons, the SRK equation of state has been combined with excess Gib...

Mathematical analysis and simulation of a discontinuous rectification column was performed using an operational strategy during the start-up before reaching pseudo-stable state in operation. The mathematical model formulated focusing on equilibrium (ES) implementing MESH equations (M: Mass balance, E: Equilibrium thermodynamics, S: Stoichiometry relations, H: Enthalpy or heat balance) to provid...

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...
