The kinetics of breaking and phenol extraction efficiency the bio-emulsion in liquid-liquid dispersed column are studied by varying bio-surfactant (lecithin) concentration, oil: water ratio, emulsification speed distributor nozzle. Among range parameters studied, maximum 79 % emulsion stability beyond 60 minutes is achieved at optimized conditions. compared with an prepared using Span-80. Even ...

a second virial coefficient correlation suitable for two different temperatures ranges, (t*)-2£180 and (t*)-2>180, where t* is rt/dhvap is presented. the equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from ttp to tc and up to high pressures. the latent heat of vaporization and density at the triple p...

in this study, a three–layer artificial neural network (ann) model was developed to predict the pressure gradient in horizontal liquid–liquid separated flow. a total of 455 data points were collected from 13 data sources to develop the ann model. superficial velocities, viscosity ratio and density ratio of oil to water, and roughness and inner diameter of pipe were used as input parameters of t...

Quasiparticles in a strongly correlated liquid with the fermion condensate: applications to high temperature superconductors Abstract A model of a strongly correlated electron liquid based on the fermion condensation (FC) is extended to the consideration of high temperature superconductors. Within our model the appearance of FC presents a boundary, separating the region of strongly interacting ...

Acoustic properties of polymeric liquids are high sensitive to free gas traces in the form of fine bubbles. Their presence is typical for such liquids because of chemical reactions, small wettability of solid boundaries, trapping of air in technological operations, etc. Liquid temperature influences essentially its rheological properties, which may have an impact on the bubble pulsations and so...

Even a single-component liquid may have more than two liquid states. The transition between them is called a 'liquid-liquid transition' (LLT). Such LLTs have recently attracted considerable attention mainly because of the fundamental interest in the physical origin of this counter-intuitive phenomenon. In this study, we report the first observation of wetting effects on LLT for a molecular liqu...
