Density is one of the most prevalent physical property used to classify and characterise fluids, not only in the environmental, cosmetics, pharmaceuticals, and food and beverage industries, but also in hydrocarbon processing industry (HPI). Petroleum products are everywhere in today’s life, and have become almost natural parts of the modern world. Numerous products used on a daily basis are der...

Improving the Modeling of Hydrogen Solubility in Heavy Oil Cuts Using an Augmented Grayson Streed (AGS) Approach — The Grayson Streed (GS) method [Grayson H.G. and Streed C.W. (1963) 6th World Petroleum Congress, Frankfurt am Main, Germany, 19-26 June, pp. 169-181] is often used by the industry for calculating hydrogen solubility in petroleum fluids. However, its accuracy becomes very bad when ...

Wax formation in hydrocarbon fluids at low temperatures is one of the harassing problems faced by the petroleum industry. The prevention of wax formation, the production of diesels more resistant at low temperatures and the design of new and better additives requires a good understanding of the crystallisation behaviour of the paraffin molecules. Better experimental techniques to study the wax ...

This paper discusses flow control of fluids through porous media, specifically related to its application in petroleum science. The flow of fluids is described by the Boussinesq equation with mixed boundary conditions; a Neumann boundary condition describes no flow at the outer boundary of the porous media and a nonlinear boundary condition describes the interaction between the porous media and...

This lecture will outline the developments over the past two years of Todd Dupont and the author on problems of flow of fluids in porous media arising from petroleum reservoir engineering. Two specific problems will be discussed and a third mentioned. The first is the single-phase flow of a non-ideal gas. This flow can be described by a nonlinear parabolic equation. The second is the two-phase ...

In recent years, the use of biodegradable fluids as liquid insulation for distribution and power transformers is spreading. The main used are natural synthetic esters, although hydrocarbons have been recently proposed. Biodegradable a much lower environmental impact than mineral oil, limiting risk soil contamination in leaks, which makes them suitable solution applications such offshore or rail...
