others. Separation results of samples with dilution ratio 4.0 are better than those
with dilution ratio 0.7. Emulsion samples with dilution ratio 4.0 adding 200 ppm
PR3 to PRe have more separated oil on the top and more separated water at the
bottom, relatively thinner rag layer in the middle. The separation results of
emulsions with dilution ratio 0.7 are worse than the samples in Figure 5.1.
Comparison of the separation resultswill be discussed in section 5.10.
