Phase Equilibira & Thermodynamic Modelling Of The Ternary System

Experimental data and predictive process models, tested at various operating conditions, have shown that supercritical fluid fractionation is a feasible process when aimed at the separation of detergent range 1-alcohols and n-alkanes with similar boiling points.

Low-Pressure VLE Measurements and Thermodynamic Modeling, with PSRK and NRTL

New subatmospheric vapor–liquid equilibrium (VLE) data for five binary 1-alcohol + n-alkane systems are presented. An all-glass dynamic recirculating still was used to measure the phase behavior of the 1-pentanol + n-nonane, 1-hexanol + n-decane, 1-heptanol + n-undecane, 1-octanol + n-dodecane, and 1-decanol + n-tetradecane systems at 40 kPa.

Fire Safety Journal

Human behaviour during evacuation of primary schools: Investigations on pre-evacuation times, movement on stairways and movement on the horizontal plane.

Children are a vulnerable group in society and less is known about their characteristics during evacuation than that of adults. This may lead to fire safety design of child centric buildings that fail to account for or acknowledge accurately the characteristics of children.

Toward Fire Safe Schools: Analysis of Modelling Speed and Specific Flow of Children During Evacuation Drills

It is without question that a child’s perspective on the world or any event is very different from the perspective of an adult. Considering the variance in physical and cognitive abilities, it is appropriate that children are deemed a vulnerable group in society with respect to fire.

The Journal of Chemical Thermodynamics

High-pressure phase behavior of six 1-decanol + n-tetradecane (solute + solute) mixtures in the presence of near- and supercritical CO2 (solvent) were experimentally studied between T = 300 K and T = 358 K using a visual static synthetic method.

The Journal of Supercritical Fluids

Phase equilibria of 3-methylstyrene, 4-methylstyrene, alpha-methylstyrene and a methylstyrene mixture (mainly 3-methylstyrene (60% mol) and 4-methylstyrene (40% mol)) in supercritical CO2 were measured using high-pressure variable-volume view cells based on the static synthetic method.
