4v`Fe,oUz7r0【论文摘要】 T 型多分岔管路是复合式分离器中的核心部件之一,本研究通过室内实验和数值模拟,研究了入口流速、相含率、分岔次数和流量配比等参数对 T 型多分岔管路中油水分离效率的影响.结果表明,在 T 型单分岔管路中油水两相发生了明显的相分高现象,但是分离效率受入口流速、相含率和流量配比的影响显著.随着分岔次数的增加,可以在更宽的入口工况和运行条件范围内保持较高的分离效率,这对于 T 型多分岔管路装置的工业应用具有重要的意义.T 型多分岔管路装置具有结构紧凑、压降损失小、分离效率较高等优点,不仅可以与其他分离部件组合成为复合式分离器,而且还可以单独用于油水分离作业.当前,油中含水无污排放是改善环境的重要环节,我们在渤海油田 QK17-2平台的原油处理系统中将采用 T 型多分岔管路装置,实现水中含油低于10.0×10-6的国际先进排放指标.

3I'N/F RcM,I0【英文论文摘要】 T-shaped pipes are one of the key components in our combination-type separator.In this study,the influences of inlet velocity,volume fraction,T-junction number and flux ratio at the two exits on the oil-water separation efficiency are investigated through experiments and numerical simulation.The results show that obvious phase separation phenomena occur in the T-shaped pipes under different conditions.With the increase of T-junction number,relatively high oil-water separation efficiency can be maintained within a wider range of inlet conditions and operational parameters,which is of practical value for the application in the industry.As a whole,T-shaped pipes have the advantages of compact sizes,lower pressure drop and relatively higher separation efficiency. Besides,it not only can be assembled with other separating components to form combination-type separator,but also may be applied independently to conduct the oil-water separation.At present,as an important measure in protecting ou...更多r environment,the residual oil in production liquid must be removed to realize no-sewage discharge in the oil industry.For example,a set ofT-shaped pipes will be installed on QK17-2 platform to improve the processing capability of its crude oil processing system,with the purpose of achieving an internationally advanced index of less than 10 ppm of oil in discharged liquid.  还原水利论文Ge/b t#AC
