煤化工装置中干燥器系统再生过程的HYSYS动态模拟和系统优化

Use HYSYS Dynamic Function to Simulate and Optimize the Dryer Regeneration System in Coal Chemical Plant

文章简单介绍了煤化工装置中干燥器运行、再生工况的工艺流程及特点,并利用HYSYS软件对干燥器的再生充压和泄放工况进行了模拟计算。通过调整孔板开孔尺寸的方法,优化了该系统在再生过程中所需氮气用量。

The article is introduced the process and characteristics of dryer operation and regeneration steps, And also uses HYSYS to simulate and calculate the regenerative charging and discharging conditions of dryer. The consumption of nitrogen used in the regeneration process was optimized due to adjustment of orifice size.
