Description

一种新型原油高效破乳剂及其制备方法
技术领域
本发明涉及化工领域。更具体地说,本发明涉及一种原油高效破乳剂及其制备方法。
背景技术
原油乳液在油品的生产和炼制中经常出现。世界上主要的粗品油都以一种乳液的形态产出。一种乳液由至少两种不相混溶的液体组成。其中之一是以一种极细的分散体如大约1mm直径的液滴悬浮于另一液体上。
这些液体的其中之一通常为水,而另一个经常是油。油有可能极细地分散于水中。在这种情况下,乳液是一种水包油型。水被称作连续相,而油被称作分散相。相反地,如果油为连续相而水是分散相,乳液就称作油包水型。大多数的原油乳液属于这种类型。
水分子之间相互吸引,同样地,油分子之间也是如此。但是在单个的水分子和油分子之间存在排斥力。排斥力在油和水的界面发生作用。表面张力将此界面面积降到一个最低值。所以,水滴在油包水乳液中是球形的。此外,单个的水滴倾向于形成聚集体,聚集体的总面积比所有液滴面积总和小。因此,一种由纯水和纯油组成的乳液是不稳定的。分散相趋于凝集,而两个分离的层面因此而形成。
界面上的排斥力抵消,如通过特种化学品在界面上的累积可降低表面张力。在技术上,许多情形通过加入熟知的乳化剂以生产稳定的乳液而开发利用这种作用。任何以这种方式起稳定作用的物质必须具有能使其同时与水分子和油分子互相作用化学组成,即它应含有一个亲水基团和一个疏水基团。
为了更多的得到品质较高的原油,许多研究应运而生,但大都破乳效果差,原油含水率较高等缺点,所以使得该破乳问题迫近需要解决。
发明内容
本发明的目的是提供一种原油高效破乳剂及其制备方法,以克服现有原油高效破乳剂存在“破乳效率低”的缺点。
为了实现上述目的,本发明采用的技术方案如下:

十二烷基磺酸钠:10~15份,引发剂:10~15份,
聚合絮凝化合物:10~15份,氢氧化钠:5~10份,
异丁醇:5~10份,甲醛:12~15份,丁二酸:3~5份,
乙氧基聚硅烷:8~15份,羧甲基纤维素:3~5份。
优选的是,所述引发剂选自聚氧丙烯、聚氧乙烯中的一种或任意组合。
优选的是,所述聚合絮凝化合物选自聚合氯化铝、聚合硫酸铝、聚合硫酸铁中的一种或任意组合。
本发明的另一个目的是提供一种原油高效破乳剂的制备方法,包括如下步骤:
步骤(1):将异丁醇、氢氧化钠和引发剂同时加入,控制温度在30~60℃,继续搅拌2~3小时;
步骤(2):将步骤(1)的反应物与乙氧基聚硅烷混合,并搅拌1~2小时;
步骤(3):将上述产物加入剩余其它物质并充分混合,即得原油高效破乳剂。

(1)采集的水样应具有代表性:用250mL细口瓶取样,取样前洗净烘干取样瓶。取样时勿用取样水冲洗取样瓶,并要取来水样全部分析。
(2)水样采集后最好立即进行测定,从取样到检测样品时间不应超过24h。
(3)采集后随即贴上标签,注明取样日期,时间,地点、取样条件及取样人。
(4)水样冷却到室温。
以下表1为进行破乳剂添加前后原油的含水量对比数据。
具体将实例1~3的原油高效破乳剂加入供试含水原油中,含水量可以1~2小时后进行测定。
表1 含油污水中加入破乳剂前后原油中含水量的对比数据
从表1可以看出,经过实例1~3的原油高效破乳剂可以水含量降低到0.42%以下。所以,本品处理后可以有效的达到原油的除水效果,其实用性较强。
