| 摘 要： | 从对原油中H2S的脱除性能、对静电场中原油乳状液破乳动力学和原油脱盐效果的影响等方面入手，将自主开发的复合脱除剂FHSS（Formulated Hydrogen Sulfide Scavenger）与典型三嗪类脱除剂（羟乙基六氢均三嗪，TRIAZINE）、新型胺类脱除剂（双（2-二甲氨基乙基）醚，BDMAEE）进行综合对比考察。结果表明：当FHSS在原油中的添加量不低于36 μg/g时，脱硫后原油的H2S质量分数不超过0.55 μg/g；FHSS与TRIAZINE的脱硫性能基本相当，而优于BDMAEE的脱硫性能；在实验考察的添加量范围（0～100 μg/g）内，FHSS与TRIAZINE、BDMAEE均对原油乳状液在静电场中的破乳速率基本没有影响，破乳动力学可近似采用一级反应动力学数学模型来描述；三者同样不影响原油电脱盐效果。

| Abstract: | Three kinds of H2S scavenger for crude oil were comprehensively compared in H2S removal performance, the influence on demulsification kinetics and desalination for crude oil in electric field. The three scavengers for comparison include a self-developed H2S scavenger FHSS, hexahydro-1,3,5-tris-s-triazine TRIAZINE and a new amine-type Bis（2-dimethylaminoethyl）ether, BDMAEE. The results indicated that H2S content in desulfurized crude oil is not more than 0. 55 μg/g if FHSS in crude oil is ≥ 36 μg/g. FHSS presents the similar removal performance for H2S to TRIAZINE，and has slightly advantage over BDMAEE. Within the experimental range of additive amount（0～100 μg/g），FHSS，TRIAZINE and BDMAEE have no influence on demulsification rates of cured oil emulsions in electrostatic field，and the demulsification kinetics could be approximatively represented by the first-order kinetics equation for chemical reactions. Meanwhile，the three scavengers all do not affect crude oil desalination. |
