Abstract	Focusing on energy conservation and process intensification, a comprehensive overview of advanced distillation technologies in the past four decades in China is presented. Novel trays, packings, and gas and liquid distributors based on the fun- damentals of such technologies are described. Hybrid distillation and distillation assisted by an external force field on the basis of process intensification principles like reactive distillation, extractive distillation, Higee technology, microwave- assisted distillation, etc. are reported. Energy-saving technologies such as dividing-wall column and internally heat integrated distillation column together with some important examples regarding the industrial application of advanced distil- lation technologies are evaluated. As a guide to develop distillation processes, a green distillation concept is proposed. Future perspectives of distillation techni- ques in China are indicated.
