以前也是这样，还是后天变成这样的？

是不是仪表问题，接反了，后者是仪表故障显示异常

新年好！首先请问你指上抽和下抽现在的温度具体是多少？阀位开度各多少？出料是否正常？如果阀位正常，量不多的话就要考虑是不是抽出口被堵或下抽阀门有问题。把近期整个分馏塔的压降趋势调出来看看是否变大了，考虑是不是分留塔结盐严重了。

上抽下抽一般是160℃，172℃

热电偶位置. 猜测高的那个是插入塔内的，低的那个是插在馏出口管线上的。

与抽出量不同有关，上抽出口量大

应该是，上面是半抽出，下面是全抽出

中段用的时上返还是下返？

Reply #122017-02-06

中段用下返塔，柴油也得用下抽出，那上抽出温度可能会比下抽稍高点，没有回流降温
