In this contribution, two approaches are followed to predict the saturated liquid density of liquefied natural gas (LNG) mixtures. In one approach, 12 cubic equations of state (EoSs), comprising the popular Peng-Robinson (PR) and Redlich-Kwong-Soave (RKS), are employed to predict the saturated liquid density of 20 LNG mixtures. In the other approach, these EoS are used in conjunction with a rec...

The basics of quantum mechanics and statistical thermodynamics were used to predict the potential energy and intermolecular forces of asphaltene molecules. The parameters associated with the chemical structure were also estimated for a specific asphaltene molecule to predict the Mie potential function. Based on the structural results, a new form of the Virial EOS with Peneloux correction wa...

The olefins polymerization process in a slurry reactor is discussed. The reaction rate dynamics was analyzed and the contributions of feed flow, gas-liquid mass transfer, polymerization reaction, and catalyst deactivation were estimated. The propylene solubility in a solvent mixture “heptane” was calculated using Soave-Redlich-Kwong equation of state. These data were then approximated by Henry-...

This study proposes a simple correlation for approximating hydrogen solubility in biomaterials as function of pressure and temperature. The pre-exponential term the proposed model linearly relates to pressure, whereas exponential is merely differential evolution (DE) optimization algorithm helps adjust three unknown coefficients correlation. estimates 134 literature data points with an excellen...

Objective: The prevalence of sexually transmitted infections in Hong Kong is not high. objective this study was to determine the risk factors that associated with occurrence local sexual assault victims, so as facilitate counseling and management victims upon their initial attendance at an Accident Emergency Department. Methods: This a retrospective cohort presented Department Kwong Wah Hospita...

The cubic-plus-association (CPA) model is an equation of state (EoS) that combines the Soave−Redlich−Kwong (SRK) equation with the association term from Wertheim’s theory as used in statistical associating fluid theory (SAFT). In the form used here, the CPA EoS does not include separate terms for the polar and quadrupolar contributions. The capabilities and limitations of the CPA model when it ...

Purpose. To compare the costs of femoral head banking versus bone substitutes. Methods. Records of femoral head banking from 1998 to 2008 were reviewed. The cost of allogenic cancellous bone graft was calculated by estimating the direct expenditure of femoral head procurement, screening tests, and storage, and then divided by the amount of bone harvested. Results. 326 females and 141 males (mea...
