精馏塔设备的设计与节能研究进展

Research progress of design and energy-saving of distillation column

精馏过程是化工过程中最耗能的过程之一。本文总结了常规精馏塔,反应精馏塔以及分隔壁精馏塔这几种类型精馏塔的研究进展。常规精馏塔的研究仍在进行,并主要体现在算法的改进与新算法的提出,以及常规精馏塔在化工高等教学的重要作用上,指出了反应精馏塔和分隔壁精馏塔是近几年精馏塔设计方面的研究热点,如反应精馏塔的模型、求解方法等,分隔壁精馏塔是一种全新的概念因而并未系统化,但却能够明显节省设备投资,并具有良好的节能前景,尤其是在与反应精馏结合后效果特别明显。文章最后对精馏塔的未来研究方向进行了展望。

Distillation is one of the most energy consumption processes in chemical industry.The research progress of three different types of distillation column is presented.Research on conventional distillation is still mainly its algorithms and its role in chemical engineering education.Reactive distillation and dividing wall column are the hot spots in recent years,such as the model of reactive distillation and solving methods.Dividing wall column is a new concept not well established,but can save equipment investment obviously and has a good energy saving prospect,especially in its combination with reactive distillation.Future study directions of distillation columns is presented.
