[化工]氯乙酸安全操作规程

作者[孙锡云] 发表于[2010-9-13 16:04:00]

氯乙酸安全操作规程

 

1、投料前打开人孔盖,仔细检查釜内各管线是否完好。否则检修后封人孔。准备投料。

2、按照要求:先投乙酸,再投硫磺。

3、检查个控制点、出气管是否畅通。投料控制阀处于关闭状态。检查温度计、比重计是否完好。

4、关闭进水阀,打开蒸汽阀。蒸汽压力控制≤0.2MPa,使釜内物料温度升至70

5、打开氯气供给阀,流量控制在510,上气管道出现回流后,进行取样。

6、当比重计1.11.2开始摇动时,关闭蒸汽阀,增加氯气流量1015.

7、在反应过程中,釜温升过快,釜夹套进冷却控制温升速度,但不得使物料温度低于80

8、反应过程中,每2小时取样一次。当比重计测的比重为1.350时,调节氯气阀,减少供氯量。釜温检测在95左右.直至物料比重达1.358,停止供氯。

9、打开蒸汽阀,使釜温升至110左右,使轻馏分流向副釜,时间10分钟。

10、静置20分钟,物料转至结晶釜。

11、检查氯化釜各控制阀,进行投料或转料,准备工作。

12、在生产过程中,出现泄漏点时,立即停车,降低釜温,使釜内处于负压状态,方可检修。
