Stability of water-in-diluted bitumen emulsion droplets

Gao, Song 06 1900 (has links)
There are several technical challenges in large scale heavy oil processing. In the oil sand industry, for example, the existence of water-in-oil emulsion in diluted bitumen produced from froth treatment presents a great challenge to the industry. In this work, the effect of different bitumen components, including asphaltenes, maltenes (deasphalted bitumen) and indigenous naphthenic acids (NAs), on the stability of water-in-diluted model oil emulsion was systematically investigated. A biodegradable polymer was developed and introduced to break the water-in-oil emulsions. The stability of water-in-oil emulsions depends on the mechanical barrier between two approaching water droplets in model oil with bitumen components. The micron-scale techniques are used in this study to study the mechanical behavior of emulsion drops due to its priority to maintain the surface area to volume ratio which is representative of the commercially observed emulsions. Several parameters, including interfacial tension isotherm, crumpling ratio and probability of coalescence, were measured to understand the interfacial reheology. Based on these experiments, the mechanical properties of emulsion drops can be evaluated in situ. A non-toxic and biodegradable polymer, ethylcellulose, was used to break up the water-in-diluted bitumen emulsion. The demulsification mechanism was studied in this work. The knowledge from this work provides improved insights on molecular mechanism of emulsion stability/demulsification and contributes to the design of demulsification systems in industrial oil sands extraction processes. / Chemical Engineering
