The vapor split ratio (R_V) adjustment plays an important role on energy efficiency during dividing wall column (DWC) operation. In order to achieve active control of R _V, this aticle presents an innovative vapor splitter driven by hydraulics. The vapor flows into main tower from prefractionation section through the rectangle hole located at the end of the partition. Vapor splitting is implemented by the change of flow resistance at the rectangular hole caused by adjusting the liquid level on the bottom plate. This design makes full use of the hydraulic properties in DWC, employing simpler construction with single tunable parameter. Numerical simulations and laboratory tests were both carried out to validate its performance in the DWC with a diameter of 600 mm. The results demonstrate that the desired R _V can be handled effectively in the approximate range from 0.5 to 2, basically satisfying the industrial demand for the gas distribution.

分隔壁塔中新型蒸气分离器的实验研究和CFD数值模拟

蒸气分流比（R _V）的调节在隔壁塔（DWC）操作过程中对能源效率起着重要作用。为了实现对R _V的主动控制，本主题介绍了一种由液压驱动的创新型蒸汽分离器。蒸汽从预分馏区通过位于隔板末端的矩形孔流入主塔。蒸汽分裂是通过调节底板上的液位引起的矩形孔内流动阻力的变化来实现的。该设计充分利用了DWC中的水力特性，采用了具有单个可调参数的更简单结构。进行了数值模拟和实验室测试，以验证其在直径为600 mm的DWC中的性能。结果表明，可以在大约0.5至2的范围内有效地处理期望的R _V，从而基本满足工业上对气体分配的需求。
