Abstract

The current practice for crude oil demulsifier selection consists of pre-screening of the best performing demulsifiers followed by field trials to determine the optimum demulsifier dosage. The method of choice for demulsifier ranking is the bottle test. As there is no standard bottle test method, there are different methodologies reported in the literature. In this work, a new approach to bottle test and field trial was described which improved significantly the selection and dosage of the demulsifier. The bottle test was optimized by measuring an accurate mass of demulsifier. This method produces repeatable results. This bottle-test methodology was benchmarked against field trial results performed in oil processing plants. The field trials were also improved to avoid the accumulation effect of demulsifier, when optimizing their dosage. The field data for the optimization of demulsifier dosage was analyzed mathematically; and a graphical method to determine the optimum range is described.

提出了湿式原油分离装置中破乳剂选择及用量优化的新方法

目前原油破乳剂选择的做法是预先筛选性能最好的破乳剂，然后进行现场试验，以确定最佳的破乳剂用量。破乳剂排序的选择方法是瓶试法。由于没有标准的瓶子测试方法，文献中报道了不同的方法。本文介绍了一种新的破乳剂瓶试和现场试验的方法，大大提高了破乳剂的选择和用量。通过对破乳剂质量的精确测量，优化了瓶试法。这种方法产生可重复的结果。这种瓶试方法是根据在石油加工厂进行的现场试验结果进行基准测试的。在优化破乳剂用量的同时，还对现场试验进行了改进，以避免破乳剂的积累效应。对破乳剂用量优化的现场数据进行了数学分析;并描述了一种确定最佳范围的图解方法。

期刊介绍： OGST - Revue d''IFP Energies nouvelles is a journal concerning all disciplines and fields relevant to exploration, production, refining, petrochemicals, and the use and economics of petroleum, natural gas, and other sources of energy, in particular alternative energies with in view of the energy transition. OGST - Revue d''IFP Energies nouvelles has an Editorial Committee made up of 15 leading European personalities from universities and from industry, and is indexed in the major international bibliographical databases. The journal publishes review articles, in English or in French, and topical issues, giving an overview of the contributions of complementary disciplines in tackling contemporary problems. Each article includes a detailed abstract in English. However, a French translation of the summaries can be provided to readers on request. Summaries of all papers published in the revue from 1974 can be consulted on this site. Over 1 000 papers that have been published since 1997 are freely available in full text form (as pdf files). Currently, over 10 000 downloads are recorded per month. Researchers in the above fields are invited to submit an article. Rigorous selection of the articles is ensured by a review process that involves IFPEN and external experts as well as the members of the editorial committee. It is preferable to submit the articles in English, either as independent papers or in association with one of the upcoming topical issues.
