Distillation is one of the important separation technologies in chemical industry, and its process intensification technology is a research hotspot in the field of modern industrial separation. Dividing wall column is a type of tower structure which is developed by a new type of fully thermally coupled distillation intensification technology, and it has significant advantages in energy saving,consumption reduction, equipment investment and operation cost. The separation principle of dividing wall column was introduced;reviewed the research progress in the separation of ternary and azeotropic mixtures by dividing wall column, extractive dividing wall column and azeotropic dividing wall column, and described the process intensification technology of combining reactive distillation and dividing wall column, that is, the research progress of the application of reactive dividing wall column in the integration of reactive distillation. At the same time, the advantages of dividing wall column technology in saving energy, reducing operating costs and reducing total annual costs were analyzed and compared with traditional distillation technology. In the end, the existing problems of the dividing wall column technology and the possible development trend in the future were pointed out.
