The energy saving principle and application advantages for mechanical vapor recompression （MVR） heat pump technology were introduced, and the development of MVR heat pump technology in salt manufacturing, emulsion concentration, papermaking, drying of solids, seawater desalination and distil- lation were summarized, and several problems for application of MVR heat pump technology were dis- cussed. The simulations for separation of small temperature difference system such as butanol-isobntanol were performed, and the energy consumption was gained. The research results showed that the MVR heat pump distillation process can save energy by 66% compared with the double effect distillation process, it promised that the MVR heat pump technology has great economic potential.
