diffusion measurement is required to get drop size distribution.
T2 distribution evolutions of emulsion samples 1 - 4 (in Table 3.2) from CPMG
measurement are shown in Figure 3.14. In the figures, T2 distribution of layered
mixture and picture of 12 h emulsion are also shown for reference.

In sample 2 and sample 4, 200 ppm demulsifier PR5 (120 μl 10 % PR5 in
xylene solution for the 60 ml emulsion sample) was added to each emulsion
