Abstract
In this study, salt separation from crude oil was investigated using nickel oxide nanoparticle absorber. The effect of parameters such as pH (4, 5, 6, 7. 8, and 9), time (15, 30, 45, and 60 min), amount of adsorbent (0.25, 0.3, 0.5, 0.75, and 1 g), and temperature (40, 50, 60, and 80 ℃) on the degree of salt separation from crude oil was studied. When the pH was decreased, the salt absorption was decreased.  Increasing the temperature increased the desalting percentage. Also in the alkali range due to the presence of OH- ions in the solution, there is a possibility of better complexation between the adsorbent and the cations. Therefore, the best adsorption was observed at near-neutral pH. The best conditions for salt absorption, pH 7, temperature 80 ℃, absorbance 0.75 g, and absorption time 45 min were obtained.
