Este hilo fue último editado por 2绿莲花 于 2 2/28-6-7 于 116:44. 蜡油加氢裂化分馏塔底泵过滤器被焦渣堵死,请问焦渣是如何产生的?

Podría ser impurezas, productos de la croke, o arcilla泥。楼主所说的分馏塔是哪套装置啊?

Estoy de acuerdo con el punto de vista de aras楼. 要进行前处理和调整工艺。

是否为焦化分馏?催化化分馏?肯定不是重整分馏?

以前是催化分 kuk. 也出现这种情况,除楼上说的情况外,还要多考虑原料性质和操作参数是否合理,塔内塔板是否结焦现象

De verdad, 这部分介质在塔内结焦的概率很低! 油浆过滤器堵了,多数是由于油浆中的催化剂引起的! 你们这里的过滤器没有反冲流程吗?一般会接一路轻柴油进行反冲!

你们的的过滤器网眼是多少目啊 现在分馏塔控制温度不大于351度,不会生成很大的焦渣
