量小,中段负荷低

结盐了把 清理清理清理盘把

结盐的话需要在线洗塔。

组分的重叠说明你们汽液两相的分离效果差,需要通过回流和温度,以及塔压得控制优化操作! 具体参数应该是通过自己实践操作得知因为即使一个设计院出来的同类装置在实际操作中还存在比较明显的差异!

汽油和柴油组份重叠有多少?汽油干点多少?柴油的初馏点多少度?

干点柴油初馏点175

催化的分馏塔设计院设计的很多都有组份重叠要想减少重叠,在不停工的情况下明确一个调整思路不断摸索调整。这是一个较长时间工作尽可能优化。但即便如此重叠基本上是必然情况我看过好几套装置实沸点均有重叠。

根据化验指标调整顶温控制住汽油干点另外用一中控制柴油馏出温度定时化验分析调整操作另外由于分馏塔顶结盐也会导致汽油和柴油严重重叠这时需要水洗置换化验分析氯离子含量。还有一种情况就是气相负荷大导致冲塔
