the effects of demulsifier; while difference between samples 1 and 3, samples 2
and 4 show the effects of clay solids.

3.5.3. Bottle test and demulsifier selection

Bottle tests were applied to find the optimal demulsifier for the emulsion
sample. In the experiment, a batch of 25 ml fresh emulsions were added to the
bottles (outer diameter 25 mm), then 200 ppm demulsifier (50 μl 10 % PRx xylene
solution for the 25 ml emulsion sample) was added to each emulsion sample.
Afterwards, all the samples were shaken by hand for 1 minute and put into the
oven at 30 0C.

Detailed procedure and parameters for NMR measurement of emulsion can
be found in appendix A.

3.6.1. Demulsifierselection from bottle test

Figure 3.9 shows 24 hours emulsion samples (dilution ratio 2.4) with solids
adding different demulsifiers PRx at 30 0C. The first sample does not contain any
demulsifiers as control. The other six samples contain 200 ppm demulsifiers PRi -
PRe, respectively. Samples with different demulsifiers have significantly different
