Figure 5.20 Water and solid content in oil layer and solid distribution in different
layers adding 200 ppm PR5 and PR6 with different amount of silicate, N∕B 4.0
Fig. 5.21 shows bar diagrams of residual water/ solid content in oil layer and
solid distribution in different layers of 24 hours emulsion (dilution ratio 0.7) using
200 ppm demulsifiers PR6 to PR6 with and without Na6SiO3. The red and black
dashed lines show the desired residual water and solid content in oil (2.0% and
0.9%, respectively).
