The abundance of affordable natural gas and continued growth in the utilization of ethylene and propylene derivatives are key drivers that are leading to the construction of large olefin plants. As is the case for most plants, the trend is to build e

Random packing is generally the preferred mass transfer device in towers operating at elevated pressure and/or high liquid rates. The performance of these towers can be improved by using modern random packing with increased capacity or efficiency. IN

In part I of this series the pure component PHCT-DNSK equation of state (EOS) was presented. In this paper the EOS is extended to describe mixtures, particularly asymmetric mixtures containing one or more low molecular weight spherical compound toget

A practical, mathematically and computationally simple, equation of state (EOS) has been developed to accurately describe pure component phase behaviour of spherical and chain-like molecules. The EOS consists of a newly developed hard sphere model an

Previous studies have shown that supercritical propane can be used to fractionate waxlike alcohol ethoxylates according to the number of ethylene oxide units and that the column temperature, pressure, and solvent to feed ratio influence the selectivi

The available sets of data for the phase equilibrium of long chain n-alkanes with 10 or more carbon atoms in supercritical ethane were studied to determine if the phase equilibrium pressure can be predicted from the number of carbon atoms and system

Part II of this series showed that at constant temperature and mass fraction a linear relationship exists between the number of carbon atoms and bubble/dew-point pressure of linear alkanes in supercritical propane. This paper investigates the extent

The virtual insolubility of synthetic wax can be improved by ethoxylating the wax with a polyethylene glycol segment to form an alcohol ethoxylate. Current methods lead to a wide ethylene oxide distribution. This work shows that supercritical propane

A significant amount of data exists for the phase equilibria of pure n-alkanes in supercritical propane, yet no data is available for mixtures of n-alkanes in supercritical propane. In this work experimental measurements of the solubility of a mixtur

Currently alcohol ethoxylates produced contain a wide distribution of the number of ethylene oxide units added. One possible method to reduce the wide distribution is with the use of supercritical fluids. From their phase behavior in supercritical pr
