介绍有民主德国等7个国家生产的破乳剂以及破乳剂选择与原油处理工艺流程和所采用装置的关系。文章特别指出,必须研制原油处理最佳工艺流程,在此基础上制造有效的脱水装置和使用适合于被处理原油的破乳剂。而不是从数百种仅适用于某一具体的并有其工艺特点的工程破乳剂中进行选择。 Describes the demulsifiers produced in seven countries, including Democracy, Germany, as well as the choice of demulsifier and the relationship between the crude oil treatment process and the equipment used. In particular, the article states that the best process for the treatment of crude oil must be developed, on the basis of which an effective dewatering device and a demulsifier suitable for the crude to be treated should be used. Instead of choosing from hundreds of engineering demulsifiers that apply only to a specific one and have its own process characteristics.
