摘　　要：节能精馏技术比普通精馏的效率更高并且能减少能量的耗费,通过对液体的回流比、操作压力以及物料的进料位置进行合理的优化。尤其是回流比参数,改变回流比,可以直接的导致精馏过程的能耗增高或者降低。本文重点分析了热泵精馏技术、多塔精馏技术、双塔精馏技术。通过对工业甲醇的节能精馏工艺的案例分析,研究了热泵精馏、三塔精馏技术和双塔精馏技术的节能效果对比。结果表明,三塔精馏节能工艺能够获得良好的使用效果。为我国节能精馏技术在化学应用领域的运用提供了应用参考平台。Energy-saving distillation technology is more efficient than ordinary distillation and can reduce energy consumption,through reasonable optimization of liquid reflux ratio,operating pressure and material feeding position.Through the case analysis of energy saving distillation process of industrial methanol,the comparison of energy saving effect of heat pump distillation,three-column distillation and two-column distillation technology was studied.The results show that the three-column rectifying energy saving process can achieve good results.It provides a reference platform for the application of energy-saving distillation technology in chemical application field in China.
