无机盐阴阳离子对稠油水包油型乳状液稳定性的影响
Effects of cationic/anionic electrolytes on the stability of heavy oil-in-water emulsions
摘要
Abstract
The effects of the concentrations of amphoteric/nonionic surfactant,inorganic/organic alkali and anionic/cationic electrolyte on the stability of heavy oil-in-water emulsions were researched. The experimental results show that the water separation rates first sharply decrease with the increase of surfactant concentrations,and then reduce gradually till the minimum value. The compositional alkali has an optimal concentration. Inorganic salts show a twofold effect on the stability of emulsions, increasing within the low salt concentration and decreasing above the high concentration of salt. The magnitude of the effects of univalent cations on water separation rates is as follows:KCl>NaCl>LiCl. And the influence of MgCl2 on the stability of emulsions is greater than that of CaCl2. The magnitude of the effects of univalent anions on water separation rates is as follows: NaCl>NaBr>NaI,and that of polyvalent is Na2SO4>NaCl>Na3PO4.关键词
