游离水分离器的选择取决于对性能的要求。这里新提出的设计准则是基于如下观点:即大多数游离水分离器都是用来从高含水原油中去除大量的水,以便较为经济地把油中含水脱到销售指标,并使污水在排放前所需的处理最少。这里并不讨论聚结装置的强化作用,而只讨论重力分离过程。在各种分离器中,由于卧式分离器占有较大比重,所以本文以大量篇幅讨论了卧式游离水分离器,而对立式游离水分离器则只作些简单的介绍。本文还论证了卧式游离水分离器与 API 分离器之间的水力相似性,并参照 API 分离器的设计方法,提出了游离水分离器的设计准则。本文还分析了容器长径比对单位处理量造价的影响,并提出了确定容器最佳长径比的方程式。
The choice of free water separator depends on the performance requirements. The new design guidelines presented here are based on the view that most free water separators are used to remove large amounts of water from high-water-content crude oil in order to more economically de-hydrate the oil to sales targets and to make the wastewater discharge The least amount of processing required before. This does not discuss the hardening effect of the coalescing device, but only the gravity separation process. In a variety of separators, horizontal separators occupy a large proportion, this article discusses a large number of horizontal free water separator, and vertical free water separator is only for a brief introduction. The paper also demonstrates the hydraulic similarity between the horizontal free water separator and the API separator. The design criterion of the free water separator is proposed according to the design method of the API separator. The paper also analyzes the influence of container aspect ratio on unit throughput, and proposes an equation to determine the optimum aspect ratio of the container.
