La temperatura de entrada,, velocidad y características no han cambiado, el bomba de valores alternos está funcionando normal,, ¿por qué no sub涨升高的?如果处理?请教各位师傅!总阀仍然卡住无法打开。

Si no se能通过蝶阀调节,只有通过甩油罐气相走空塔预热。关键是控制好分馏塔压力,预热速度不能过快,严防出现温度大幅波动,预热成功后及时改进分馏系统。如果改走空塔也出现不畅问题。应切除系统重新用蒸汽贯通流程。

¿Su的意思是走甩油到空塔放低压瓦斯?那这样火炬能受得了?

预热到温度不就换塔了吗?

No aumenta基本不涨,后来用蒸汽顶了一下就好多了,可能是堵了

温度底在1左右,温度顶在 28左右,达不到切塔条件

检查预热塔冷凝的油有没有及时排掉或进料短接吹扫蒸汽是否关闭。
