罐区储罐新增增气相平衡管线后的疑惑?

这个主要就是槽车与平衡管道连接的密封性不好造成的。建议要么改进这个气相连接密封效果;另外临时措施也可以考虑卸车时将氮封压力降低,减少卸料期间氮气补加,卸完料后恢复正常。谢谢!

卸车时,储罐内压力逐渐升高,槽车顶部气相压力逐渐降低。储罐内压力低于罐内设定维持压力时,通过氮气补,当压力超过维持压力的设定值,氮气阀门关闭,排气管阀门打开,和槽车顶部的气相管线联通的,可以起到平衡作用。 装车时,储罐内压力逐渐降低,槽车顶部气相压力逐渐升高。随着液位的下降,储罐内压力低于罐内设定维持压力时,氮气阀门打开补氮气,当达到维持压力的设定值,氮气阀门关闭。

液体和气体体积互相置换,除非漏气,理论上罐内压力不会下降

气相平衡管三种功能:1、防止有害物质泄漏到大气中;2、保持槽车与储罐压力平衡,保证卸料;3、防止空气进 入槽车或储罐形成爆炸性混合物。 如果密封不好,做的平衡管就没有意义。
