摘要： The present invention relates to a process for purifying unsaturated compounds, said purification being performed in a plant which comprises at least two evaporators which are connected in such a way that a portion of the unsaturated compound is circulated, the vapours condensed in the first evaporator being isolated and the vapours condensed in the second evaporator being introduced into the first evaporator, which is characterized in that the mass flow with which the condensed vapours are isolated from the mixture to be purified in the first evaporator is less than the mass flow with which the condensed vapours from the second evaporator are introduced into the first evaporator.The present invention further describes a plant for performing the process, which comprises at least three evaporators which are connected to one another such that the residue of the first evaporator remaining in the liquid phase can be passed into the second evaporator, the condensed vapours of the second evaporator can be passed into the first evaporator and the residue of the second evaporator remaining in the liquid phase can be passed into the third evaporator, and the condensed vapours of the third evaporator can be passed into the second evaporator.
摘要翻译：本发明涉及纯化不饱和化合物的方法，所述纯化在植物中进行，所述植物包括至少两个蒸发器，所述蒸发器以不饱和化合物的一部分循环的方式连接，在第一蒸发器中冷凝的蒸汽为隔离并且在第二蒸发器中冷凝的蒸气被引入第一蒸发器，其特征在于，冷凝的蒸气与要在第一蒸发器中净化的混合物分离的质量流小于质量流，来自第二蒸发器的冷凝蒸气被引入第一蒸发器。本发明还描述了一种用于执行该方法的设备，该设备包括至少三个彼此连接的蒸发器，使得残留在液相中的第一蒸发器的残余物可以进入第二蒸发器，冷凝的蒸气第二蒸发器可以进入第一蒸发器，并且残留在液相中的第二蒸发器的残余物可以进入第三蒸发器，并且第三蒸发器的冷凝蒸气可以进入第二蒸发器。
