梳型原油破乳剂的合成与应用

Synthesis and Application of Comb Crude Oil Demulsifier

摘要:

以异丙醇为溶剂，氯铂酸为催化剂，在反应温度为95 ℃时，含氢硅油与烯丙基聚醚酯、甲基丙烯酸、甲基丙烯酸甲酯发生硅氢化加成反应，制备出以含氢硅油为主链的多支链梳型聚硅氧烷原油破乳剂。通过探讨烯丙基聚醚酯、甲基丙烯酸、甲基丙烯酸甲酯这3种反应物的配比不同对延安原油的脱水效率的影响，确定了最佳配比3:2:2。通过破乳性能测试实验，考察了该类梳型原油破乳剂对延安原油的破乳效果。将其与 TA-1031按比例3:2复配进行破乳实验，在总加量为100 mg?L-1，脱水温度为60 ℃时，脱水率达到91.02 %。

Abstract:

The comb polysiloxane crude oil demulsifier that the main chain was silicone oil and had multi-branched chain was synthesized by the hydrosilylation reaction with the allyl polyether acrylate, methyl acrylate, methyl methacrylate，using isopropanol as the solventand, chloroplatinic acid as the catalyst and at the reaction temperature of 95℃. The author determined the optimum ratio of 3:2:2 by investigating the effects on the dehydration efficiency of the Yan'an crude under different ratios of the allyl polyether ester, methacrylic acid, methyl methacrylate and study the function of comb crude oil demulsifier on the Yan'an crude oil through the the demulsification performance test. In addition, blending the product with TA-1031 in proportion 3:2 at the total plus the amount of 100mg?L-1, at the dehydration temperature of 60℃, made the dehydration rate achieve 91.02%.
