Effect of ph and salinity on stability of crude oil water emulsions

الملخص EN

In this paper, laboratory experiments have described to investigate the effect of pH and salinity of water on the stability of emulsions.

The emulsion was prepared by mixing the water and crude oil (4:1) volume ratio and shaking by hand.

The water's pH was studied in this work (1, 4, 8, 12) and NaCl concentration was (0, 10, 40, 70, 100, 140) gram/liter.

The results show that the stability of emulsions decreases with increases the salinity concentration.

The water's PH influences on emulsions stability.

It was found that at pH=12 there is unstable emulsion formed and stable emulsion formed at pH=1.
