摘要
石油联合站原油脱水工艺面临效率低能耗高的问题,针对脱水机理进行分析,采用陶粒聚结材料对传统三相分离工艺实施改造,开发分散控制系统实现工艺参数的智能调控,研究表明,陶粒材料具有良好的亲水性,在进料流速20 m/h、含水率30%、孔隙度0.85、填充厚度250 mm的条件下达到最佳脱水效果。经过工艺优化,分离器出口含水率稳定在1%以下,二级分离过程无需加热,破乳剂用量大幅降低,每年可节约大量燃料气,取得显著的经济效益,研究成果为提高原油脱水效率降低运行成本提供了技术支撑,具有良好的推广应用前景。
The crude oil dehydration process at the petroleum joint station faces the problem of low efficiency and high energy consumption.Based on the analysis of the dehydration mechanism,the traditional three-phase separation process is modified using ceramic aggregate materials,and a decentralized control system is developed to achieve intelligent control of process parameters.Research shows that ceramic aggregate materials have good hydrophilicity and achieve the best dehydration effect under the conditions of feed flow rate of 20 m/h,water content of 30%,porosity of 0.85,and filling thickness of 250 mm.After process optimization,the moisture content at the outlet of the separator remains stable below 1%,and the secondary separation process does not require heating.The amount of demulsifier used is significantly reduced,and a large amount of fuel gas can be saved annually,achieving significant economic benefits.The research results provide technical support for improving crude oil dehydration efficiency and reducing operating costs,and have good prospects for promotion and application.
