Figure 5.21 Water and solid content in oil layer and solid distribution in different
layers adding 200 ppm PR3 to PRβ with and without silicate, N∕B 0.7

In all the samples, residual water and solid content in oil with silicate are
smaller than that without silicate. With silicate, less solids stay in the oil and more
solids settle to the bottom.
