腐植酸盐对吉林稠油乳化作用研究

Research of Humic Acid Salt as Emulsifying Agent of Jilin Heavy Oil

以乳状液稳定性为指标,在室内评价了腐植酸盐对吉林稠油的乳化作用。结果表明:腐植酸盐可以作为稠油乳化剂使用,具有一定的乳化降黏作用,但因原料、生产工艺不同,乳化性能存在差异。腐植酸盐与氢氧化钠复配使用可大大提高乳化性能。腐植酸盐可有效提高表面活性剂对稠油的乳化效果,其中对非离子表面活性剂的效果最好,对阴、阳离子表面活性剂作用相当。

The emulsifying performance of humic acid salt as emulsifier is studied by evaluating the stability of emulsion within doors.The results indicate that the humic acid salt can be used as emulsifying agent to reduce the viscosity of heavy oil.The emulsifying effect is different for different humic acid salts produced by different manufacturing technique from discrepant material.The emulsibility of humic acid salt can be improved obviously by joining sodium hydroxide.Humic acid salt can improve the stability of emulsion produced by surfactant,especially the non-ionic surfactants.
