石油乳液一般是油包水型,其中天然存在的水或盐水的细滴分散在作为连续相的油中。这些乳液通常非常稳定,而且长期存放不会介除。本文是关于原油在开采过程中遇到的石油乳液的处理,目的是使油从水中分离出来。乳化型石油破乳剂 UH6535能介除油包水型石油乳液,它在油水界面上有表面活性,可以引起或帮助乳液破乳。本文介绍一种油包水型石油乳液的破乳过张,过程的特点是用一种油溶性的超高分子量的聚氧化烯烃的乳化型破乳剂 UH6535,所谓聚氧化烯烃是由氧化烯烃聚合而成,采用的催化剂包括:(1)一种有机铝化合物如三乙基铝。(2)一种螯合剂如乙酰丙酮。(3)水。当有机铝化合物与水和一个螯合剂反应时,可作为氧化烯烃聚合的极好的催化剂。这个聚合过程通常能生成高聚物,有时得到的产品溶液其特性粘度比需要的过高。这给应用带来了很多麻烦。本文介绍一种改良的催化体系,并简要地引入一种聚合的机理。不仅可能制备一种低平均分子量的 UH6535的聚合物([η]=1.4～2)而且产物可以被水乳化。乳化型石油乳剂 UH6535是一种比其他商品更有效的破乳剂。它比单纯的溶剂型UH6535要好得多,这就使它在工业上非常有用。
Petroleum emulsions are generally water-in-oil forms in which fine droplets of naturally occurring water or brine are dispersed in an oil as a continuous phase. These emulsions are usually very stable, and will not be mediated by long-term storage. This article deals with the processing of petroleum emulsions encountered during the recovery of crude oil in order to separate the oil from the water. Emulsified petroleum-based demulsifier UH6535 is a water-in-oil emulsion that is surface-active at the water-oil interface that can cause or assist emulsion demulsification. This article describes a water-in-oil emulsion of emulsion-breaking too much, the process is characterized by an oil-soluble ultra-high molecular weight polyoxyalkylene emulsion demulsifier UH6535, the so-called polyoxyalkylene olefin polymerization is The catalysts employed include: (1) an organoaluminum compound such as triethylaluminum. (2) a chelating agent such as acetylacetone. (3) water. When the organoaluminum compound is reacted with water and a chelating agent, it can be an excellent catalyst for the polymerization of alkylene oxides. This polymerization process usually produces a polymer, sometimes resulting in an inherently higher intrinsic viscosity than required. This has brought a lot of trouble to the application. This article describes an improved catalytic system and briefly introduces a mechanism for polymerization. It is not only possible to prepare a polymer with a low average molecular weight of UH6535 ([η] = 1.4-2) and the product can be emulsified with water. Emulsified Petroleum Emulsion UH6535 is a more effective demulsifier than other products. It is much better than pure solvent type UH6535, which makes it very useful in industry.
