Description

一种用于树脂液的破乳剂的制备方法
技术领域
本发明涉及破乳剂领域,尤其涉及树脂液用破乳剂。
背景技术
破乳剂是一种用于脱水的非离子型表面活性剂,树脂液中的水分脱出来,使树脂液含水量达到技术控制指标;用于树脂液生产中可提高树脂液品质。肥皂气味。易溶于水,水溶液澄清透明。在树脂液中,含有一些水,如果不及时脱水则会增肌泵、管线和贮罐的负荷,引起金属表面的腐蚀和结垢,而排放的水中含油也会造成环境污染树脂液的浪费。因此,在生产时需要对树脂液进行破乳去水和污水除油。破乳的方法分为沉降法、加热法、电脱水法和化学法等,采用较多的是化学脱水法,即将破乳剂加入至树脂液中,在常温或升温的条件下使树脂液破乳脱水。
从目前来看,我国国内现在使用的破乳剂大部分是聚氧依稀聚氧丙烯嵌段聚醚型的非离子表面活性剂,但是目前使用的大多数聚醚型破乳剂需要需要较高的温度或者需要一定的外加电场,使用的剂量较大并且需要较长时间作用才能达到良好的破乳效果,这就导致生产效率低下,且能耗增加。
发明内容
针对上述技术问题,本发明的目的在于提供一种能够实现在低于40℃下对树脂液进行破乳且不需要外加电场而破乳速度较快的低温破乳剂及其制备方法。
为了实现上述技术效果,本发明采用以下技术方案予以实现:
一种破乳剂,包括以下质量份数的原料:
本发明的技术方案为:
本发明提供一种低温破乳剂,原料包括以下重量百分比组分:40-50%改性聚醚嵌段共聚物、15-20%脂肪胺醚、10-15%磺化聚丙烯酰胺、10-15%甲醇和余量水;
所述改性聚醚嵌段共聚物的制备原料包括起始剂:二乙烯三胺和酚胺树脂、催化剂、环氧化物和扩链剂;以100%计,所述起始剂、催化剂和环氧化物的重量百分比分别为:起始剂:7-8%二乙烯三胺和35-45%酚胺树脂、2.5-4.5%催化剂和余量的环氧化物;
所述起始剂、催化剂和余量的环氧化物反应制得聚醚嵌段共聚物,所述聚醚嵌段共聚物与扩链剂以1:3-4的摩尔比进行扩链反应,制得所述改性聚醚嵌段共聚物。
本发明的低温破乳剂,其主要成分为聚醚嵌段共聚物,端基包含羧基、氨基、醚基及羧基等多种活性官能团,复配脂肪胺醚和磺化聚丙烯酰胺,使所述低温破乳剂具有高效能的表面活性,可以对原油中的油包水、水包油乳状液等乳化形式进行吸附破乳,极强的表面活性使其极易吸附在油水面膜上,使面膜强度迅速降低,油和水迅速集成较大颗粒,经絮凝、聚结达到油水分离。本发明的低温破乳剂,渗透能力极强,在较低温度下(大约40℃以下)即可实现原油的破乳脱水,显著降低了油水分离阶段的能耗。
本发明的有益效果为:
本发明的低温破乳剂,基于破乳性能优化的目的,对所述聚醚嵌段共聚物进行扩
链改性,所述扩链剂为二元羧酸;综合破乳脱水效率和最终脱水率,进一步优选,所述扩链剂为己二酸,以相应摩尔量的己二酸为扩链剂时,不仅使所述改性聚醚嵌段共聚物具有合适的、较大的相对分子质量,容易在乳液截面形成含有适量亲水、亲油基团的膜,从而破坏原乳化液滴,使其中的水被释放,达到优异的油水分离的效果。
本发明的低温破乳剂的制备方法,基于各组分组成,制定相应的工艺步骤和各组分添加混合顺序,复配得到体系稳定的低温破乳剂药剂体系。

详细的描述。显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动的前提下所得到的所有其它实施方式,都属于本发明所保护的范围。
