Simultaneous Effects of Ionic Surfactant and Salt on Drop-Interface Coalescence
Volume 6, Issue 4 , October 2009, , Pages 73-86

  In this research, the effect ofmixed salts together with mixed ionic surfactants on dropinterface coalescence time was studied for the system of water (d) / toluene(c) as a model system. Sodium dodecyl sulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB) as anionic and cationic surfactants were ...  Read More

Predicting Solubility of Isotactic Poly (1-Butene) in Different Organic Solvents by Modified UNIQUAC
Volume 5, Issue 4 , October 2008, , Pages 39-48

  The UNIQUAC activity coefficient model is extended to predict solid-liquid equilibrium of isotactic crystalline poly (1-butene), iPBu-1, in different organic solvents. The UNIQUAC activity coefficient model used in this work is based on the concept of group contribution and consists of combinatorial, ...  Read More

The Modified Lennard-Jones and Devonshire Equation of State
Volume 5, Issue 3 , July 2008, , Pages 52-61

  Lennard-Jones-Devonshire equation of state is an old but theoretical based EOS. The concept of the nearest neighboring molecules or coordination number is proposed to be a function of temperature and volume, whereas it is a constant in the original. The dilute gas and hard sphere limits of molecules ...  Read More

Solid Phase Equation of State Application for Wax Formation Prediction in Petroleum Mixtures
Volume 5, Issue 2 , April 2008, , Pages 23-33

  Precipitation ofsolid paraffins is one ofthe most common problems in the oil industry, imposing high operating costs. There have been a great many efforts for the prediction of solid paraffins precipitation up to now. Most of them were based on activity coefficient models accounting to solid phase non-ideality ...  Read More

Phase Inversion in a Batch Liquid – Liquid Stirred System
Volume 5, Issue 2 , April 2008, , Pages 55-63

  "> Phase inversion phenomenon occurs in many industrial processes including liquidliquid dispersions. Some parameters such as energy input or the presence of mineral compounds in the system affect this phenomenon. The aim of this research is to study the speed of rotation or energy input at a range ...  Read More

On the Selection of Proper Thermodynamic Conditions for the Gas Antisolvent Process (GAS) at Nearcritical and Supercritical Conditions
Volume 3, Issue 4 , October 2006, , Pages 17-22

  In this work the volume expansion for the binary systems of ethanol and toluene, as industrial organic solvents, in the presence of nearcritical and supercritical carbon dioxide, CO2, at a temperature range of 293 to 333 K has been meticulously measured. The effect of the temperature and pressure of ...  Read More

Prediction of Vapor-Liquid Equilibria Using CEOS /GE Models
Volume 2, Issue 1 , January 2005, , Pages 71-81

  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, ...  Read More
