在海洋浮式采油平台上 ,由于海浪运动会导致分离器中的油、气和水三相混合 ,所以在这种生产条件下进行三相分离是极其困难的。Natco公司先前必须依赖昂贵的物理测试方法来评价分离器的设计 ,但是采用这种工艺方法人们并不能直观地观察到分离器中液相的运动情况。通过采用计算机流体动力学 (CFD)软件研究分离器内部的流体动力学 ,工程师们便能够直观地看到即便是在最急剧的海浪运动过程中分离器内所发生的油、气和水的分离情况。设计人员已经认识到 ,目前通常采用的水平折流板结构的分离器的三相分离效果是极差的 ,而采用常规多孔折流板结构的分离器则会由于孔洞过多而影响三相流分离效果。采用新的设计概念设计的分离器内部折流板会使分离器免受海浪运动的影响 ,使得分离时间明显地缩短
On offshore platforms, it is extremely difficult to carry out three-phase separation under such production conditions because the wave motion results in a three-phase mixture of oil, gas and water in the separator. Natco had previously had to rely on costly physical testing methods to evaluate the design of the separator, but with this process one can not intuitively observe the movement of the liquid phase in the separator. By using CFD software to study the fluid dynamics within the separator, engineers can intuitively see the separation of oil, gas and water occurring in the separator even during the most drastic wave motion Happening. Designers have recognized that the three-phase separation of horizontal baffle structures commonly used today is extremely poor, whereas separators employing conventional porous baffles can affect three-phase flow due to excessive holes seperate effect. Separators designed with a new design concept Internal baffles will protect the separator from the effects of wave motion, resulting in significantly shorter separation times
