Abstract

Emulsions in petroleum production pose challenges like equipment corrosion, pipeline pressure drops, pumping costs, and catalyst poisoning, leading to increased production costs and technical and environmental issues. The complexity of emulsions necessitates using cost-effective and efficient de-emulsifiers for effective treatment. Desalting units are often installed in crude oil production units to remove water-soluble salts from an oil stream. To optimize this process, the desalting unit should be modeled. The research employs Response Surface Methodology (RSM) to analyze the efficiency of the desalting unit based on various input parameters. The result shows that the mentioned model agrees with the experimental data. The experiments were designed using response surface methodology; these parameters and their interaction are significant, and determination coefficient R2 for water content and salt concentration equal 0.9246 and 0.9901 in respective in addition difference between Radj and Rpred less than 0.2 for two responses, Radj and Rpred for water content 0.8491 and0.6082 and salt concentration 0.9803 and 0.9464, respectively. The result revealed that minimum water content of 0.03%(V/V) and salt concentration of 85 ppm, which agreement with predicted responses, was 0.05%v/v and 70 ppm, respectively, when the temperature was 45.1 °C, API 29, initial water content was 2.07 and initial salt concentration was 5344.04, respectively.

优化伊拉克原油脱盐装置性能的响应面方法
石油生产中的乳状液会带来设备腐蚀、管道压降、泵送成本和催化剂中毒等挑战,从而导致生产成本增加以及技术和环境问题。由于乳状液的复杂性,必须使用具有成本效益的高效去乳化剂来进行有效处理。脱盐装置通常安装在原油生产装置中,用于去除油流中的水溶性盐类。要优化这一过程,必须对脱盐装置进行建模。研究采用响应面法(RSM),根据各种输入参数分析脱盐装置的效率。结果表明,上述模型与实验数据一致。实验采用响应面方法进行设计;这些参数及其交互作用显著,含水量和盐浓度的确定系数 R2 分别为 0.9246 和 0.9901,此外,两个响应的 Radj 和 Rpred 之差小于 0.2,含水量的 Radj 和 Rpred 分别为 0.8491 和 0.6082,盐浓度的 Radj 和 Rpred 分别为 0.9803 和 0.9464。结果表明,当温度为 45.1 °C、API 为 29、初始含水量为 2.07、初始盐浓度为 5344.04 时,最低含水量为 0.03%(V/V)、盐浓度为 85 ppm,分别为 0.05%v/v、70 ppm,与预测反应一致。
