Effect of process parameters on bitumen emulsions

Chemical Engineering and Processing: Process Intensification, 2005
Abstract 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.

Early age evolution of rheological properties of over-stabilized bitumen emulsion-cement pastes

Construction and Building Materials, 2016
This paper focuses on the early age evolution of consistency and rheological properties of fresh bitumen emulsion-cement (BEC) pastes. The tested BEC pastes were fabricated using a Portland limestone cement and an over-stabilized bitumen emulsion and ...

Waterproofing latex-bitumen emulsions

Polymer Science. Series D, 2008
Bitumen 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.

Electrical properties of bitumen emulsions

Fuel, 1995
The 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.

The combustion of bitumen-in-water emulsions

Fuel, 1991
Abstract 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 ...

Roles of Various Bitumen Components in the Stability of Water-in-Diluted-Bitumen Emulsions

Journal of Colloid and Interface Science, 1999
An 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.

[On bitumen emulsions in water].

Acta cientifica venezolana, 2005
The 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 ...

The factors affecting on Bitumen Emulsion properties

2010 International Conference on Chemistry and Chemical Engineering, 2010
Need to proper roads and highways will increase with increasing automotive industry and development of cities and countries. Among petroleum products used in road construction and asphalt application for soil stability and adhesion between layers of asphalt are bitumen soluble and Bitumen Emulsions.

Preparation And Inversion of Bitumen-Water Emulsions

Technical Meeting / Petroleum Conference of The South Saskatchewan Section, 1995
Abstract 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.

The effect of naphtha to bitumen ratio on properties of water in diluted bitumen emulsions

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2002
Abstract Properties of water in naphtha-diluted bitumen emulsion depend on naphtha to bitumen ratio. There is a critical dilution ratio, at which the system properties change abruptly. The critical dilution ratio coincides with an onset of asphaltene precipitation. The critical diluted ratio for the bitumen and naphtha used in this study is 4.
