Subject(s):

Dissertation note: Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang – 2009 Abstract: The formation of water in the crude oil emulsion is the most important because it increases the volume and viscosity of the emulsion and adversely affects the recovery and clean up. Hence, it is important to understand the processes involved in formation and breaking of w/o emulsions. The objectives of this study are to stabilize the water-in-crude oil emulsions and to study the rheology of water-in-crude oil emulsions. In this study, the w/o emulsions is prepared into three volume ratios (50-50% w/o, 30-70% w/o and 20-80% w/o) by using two types of crude oil (Kuwait and Dubai) with four different surfactants (SDDS, Triton-X-100, Tween-80 and Span-80). The w/o emulsions was stabilized, then characteristics of the emulsions were measured by using Rheometer and tensiometer. The results show that the indicator for the w/o emulsions stability is the volume water separated. Besides, the stability of the emulsions is influenced by their characteristics. It found that emulsion stability decreases with increasing volume fraction. The effective viscosity of water-in-oil emulsions depends mainly on the volume fraction of dispersed phase and temperature, along with several minor effects, such as shear rate, shear stress and viscosity of oil.
