重整气变压吸附提氢装置运行问题分析及应对措施

Analysis of operational status and solutions to pressure swing adsorption hydrogen unit for reformer gas

本文分析了盘锦北方沥青燃料有限公司68 000 m3/h重整气变压吸附提氢装置的运行情况。该装置开工不到一年内出现了产品氢纯度低和杂质脱除率不合格的问题。经分析发现产品氢气中C5组分含量高,C5组分已经穿透吸附器最上层分子筛,造成吸附剂床层整体性能下降。优化操作条件并将现有催化剂再生,解决了产品不合格问题,实现装置长周期稳定运行。

This paper analyzed the operational status of 68 000 m3/h pressure swing adsorption unit for reformer hydrogen in Panjin north asphalt fuel Co.,Ltd..A few issues appeared in less one year since start-up, including low hydrogen concentration and impurity removal rate.It was found that C5 have penetrated the top molecular sieves, leading to the high C5 concentration in product H2.Similarly,it resulted in poor adsorption and desorption performance for the whole absorbent beds.Qualified product H2 and long-term stable operation were achieved after optimizing operational conditions and adsorbent regeneration.
