停工时反应压力大于再生压力,卸剂时保证汽提段常量归零待生线路密度回零,切断反再系统,加完大盲板后,在进行多次转剂卸剂。

正常计划停工,切断反应进料后,维持正常差压,两器催化剂再循环一段时间,维持再生器温度600°C左右,目的充分烧去催化剂上面的焦炭,采样观察再生剂颜色,根据情况停止两器循环;这时将再生线路的阀门关闭,适当提高反应压力大于再生压力,将反应器里面的催化剂转入到再生器、加盲板、隔断反应与后续岗位;卸剂路线畅通,就可以了,为了保证安全及卸剂速度,一般温度控制在450°C左右;

我们这是卸完催化剂待分馏塔温度降低后加装盲板。

唉,每个公司都有不同,俺们是在反应器里通风循环烧焦就可以,看反应效果,不好了再卸出来筛选,添加新剂

你说的是催化裂化部分的装置吗? 怎么感觉是固定床反应器里的催化剂再生处理啊.....
Reply #82018-05-20
同样看不明白楼上说的 我们一般是卸出的平衡剂开工的时候再加进再生器里面去

固定床反应器的催化裂化啊? 这个是第一代催化裂化的形式,还在运行?
Reply #102018-05-27
差异有,楼上说的不是催化裂化吧

微正差压,逐渐关小滑阀至全关,最后关塞阀
