精馏过程的节能,对于减少能源消耗,降低生产成本和保护环境具有十份重要的意义。在精馏过程中可以采用最适宜回流比操作和最佳进料状态,使用中间冷凝器和中间再沸器,多效精馏技术、热泵精馏技术。合理安排多组分物料分离流程,提高过程的分离效率、提高物料回收率,进而降低能耗。并介绍我国精馏过程的节能现状与趋势。
Energy-saving distillation process, for reducing energy consumption, reduce production costs and protect the environment is of great significance. In the distillation process can be the most appropriate reflux ratio operation and the best feed state, the use of intermediate condenser and intermediate reboiler, multi-effect distillation technology, heat pump distillation technology. Reasonable arrangements for multi-component material separation process to improve the separation efficiency of the process and improve material recovery, thereby reducing energy consumption. And introduce the current situation and trend of energy-saving in the distillation process in our country.
