5.7.3.4. Water content in oil layer after emulsion separation
Table 5.6 shows water content at different positions of oil layer (Figure 5.15
shows positions of sampling) in partially separated diluted bitumen emulsion with
200 ppm PR5 and 1x10^4 M silicate (photograph of the sample is shown in
Figure5.1). From the result, water content in oil layer is not homogeneous. Water
content increases from the top to the bottom of oil layer after adding demulsifier
and silicate. This indicates the sedimentation effects by gravity.
