Roles of Various Bitumen Components in the Stability of Water-in-Diluted-Bitumen Emulsions
Journal of Colloid and Interface Science, 1999An experimental study was conducted to evaluate the effectiveness of the various components of Athabasca bitumen in stabilizing water-in-diluted-bitumen emulsions. The solvent used to dilute the very viscous bitumen was a mixture of 50:50 by volume of hexane and toluene.

Construction and Building Materials, 2016
Abstract Chitosan contains amine and amino groups which have the ability to generate cationic type surfactants when combined with H + ions. It has a high potential for use as a cationic emulsifier for negatively charged siliceous aggregates for paving of roads in Sri Lanka.

Effect of process parameters on bitumen emulsions
Chemical Engineering and Processing: Process Intensification, 2005Abstract Bitumen emulsification experiments have been carried out in a continuous pilot scale rotor-stator facility. The effects of the following process parameters, namely the temperature of the aqueous phase and bitumen, the rotor speed, the dispersed phase content, the bitumen grade and the emulsion flow rate were investigated.

Electrical properties of bitumen emulsions
Fuel, 1995The complex dielectric constant (permittivity) of water-in-bitumen emulsion was measured for emulsions with water volume fractions ranging from 0 to 0.5, in steps of 0.1. Significant departure from theoretical calculation was observed, and was attributed to the presence of polar components in the bitumen.

Waterproofing latex-bitumen emulsions
Polymer Science. Series D, 2008Bitumen emulsions are developed based on new anionic emulsifiers, which are wastes of chemical industry. Optimal concentrations of emulsifiers in bitumen emulsions are established. The developed bitumen emulsions are not inferior in their process and service parameters to known domestic and foreign analogs.

The combustion of bitumen-in-water emulsions
Fuel, 1991Abstract The combustion behaviour of bitumen-in-water emulsions has been investigated using suspended and falling droplet techniques together with some experiments of spray combustion using an air blast atomizer. Single droplet measurements have been made using a commercial soft bitumen-in-water emulsion (Orimulsion) and similar mixtures with varied ...

ATOMIZATION CHARACTERISTICS OF BITUMEN CRUDE-WATER EMULSION
Atomization and Sprays, 1998Measurements of the angular patterns of scattered light were carried out on sprays of an emulsion of bitumen crude (70% by weight) in water produced by a home-built air-assisted atomizer at different air flow rates. The size distribution of the bitumen droplets was previously measured by optical microscopy.

[On bitumen emulsions in water].
Acta cientifica venezolana, 2005The most important factors, controlling the process of emulsification of highly viscous hydrocarbons in water, which are responsible for keeping the stability and other properties of these systems, are discused in this article. The effect of non-ionic surfactants, such as nonil phenol ethoxilated compounds on the interfacial behavior of bitumen/water ...

Preparation And Inversion of Bitumen-Water Emulsions
Technical Meeting / Petroleum Conference of The South Saskatchewan Section, 1995Abstract The preparation and inversion of relatively large droplet Athabasca Bitumen-in-water emulsions have been examined experimentally, The emulsions were prepared using small quantities of NaOH, followed by cooling to 20 ° C.
