摘　　要：精馏和反应过程的节能,对于减少能源消耗,降低生产成本和保护环境具有十分重要的意义。在精馏过程中可以采用最适宜回流比操作,采用最佳进料状态,使用中间冷凝器和中间再沸器,高效精馏、热泵精馏。合理安排多组分物料分离流程,直接利用过程热量及开发应用高效换热器等措施。在反应过程中应重视反应途径的合成,反应器的合理选择和高效反应器的设计开发、适宜反应条件的选取和优化等问题。Energy conservation in distillation and reaction process is important on reducing fuel consumption, decreasing production costs and environmental protection. Measures are adopted such as optimum reflux ratio, optimum feed conditions, middle condenser and middle reboiler, multiple effect distillation, heat pump distillation, as well as arrangement of multicomposition separation process, heat utilization in distillation process, development and application of concentrated heat exchanger. For reaction process, great importance should be attached to compound of reaction ways, rational selection of re- actors and development of efficient reactors, selection and optimization of reaction conditions.
