一种回热型TSA空分纯化再生系统的节能效果分析

An Energy-Saving Analysis for a Regenerative TSA Air Separation Prepurification Regeneration System

为了提高纯化系统的能源利用率,降低空分纯化系统的能耗,本文提出一种在传统双吸附器系统中增设回热器以回收再生阶段排出氮气中部分热量的纯化流程,并以公开的实际制氧厂工况为例进行了节能效果分析。计算表明,采用带回热器的TSA空分纯化再生系统后,最大可使污氮气再生电加热量减少56.0%。

In order to improve the energy efficiency and reduce the energy consumption of air separation prepurifieation system, a regenerator was proposed in the traditional bi-adsorber prepurification system to recover the energy of the discharged purge N2 during the regeneration step and the rate of energy-saving was calculated for an open running oxygen factory. The result showed that with a regenerator in the traditional bi-adsorber prepurifieation system, the maximum rate of energy-saving of the electricity power for regeneration could be 56%.
