请问再生器提升器到还原罐压差一般在多少
Reply #42017-01-08
如果调整催化剂循环量,只能在CRCS系统调循环速率是吧!这个压差是可以调控吗
Reply #52017-01-08
这个差压是循环速率控制方案的副回路,正常应该是循环速率给定点与实际平均循环速率之间偏差赋予差压给定值。不过初始做催化剂提升实验的时候也可将差压自动控制,给提升二次气设定值。这个控制是三串级控制,可以从下往上投自动,只是差压投自动不投串级循环速率波动大而已

循环速率的调整,是根据再生器料位高低来决定吗?料位高,循环速率调快一些?
Reply #72017-01-10
不是,循环速率相当于再生器烧焦反应的处理量,要求必须稳定;再生器料位通过反应器下部催化剂提升系统调节。
Reply #82017-01-10
料位高了,就靠调节二次风量来控制是吧!循环速率是不是要根据待生催化剂焦炭含量来考虑
Reply #92017-01-11
我这边一般 20-30kpa
Reply #102017-01-11
差压越低越好,催化剂磨损少;波动范围越小越好,循环速率稳定
Reply #112017-01-11
靠反应器下部提升器的二次风量控制。循环速率选取依据烧焦曲线选取,碳含量高的时候循环速率越大,否则积碳会越来越高,但也有上限,碳含量很高循环速率又很大的时候,炭容易烧不透发生超温事故
Reply #122017-01-12
一般焦炭含量控制在百分之多少,是4——6吗
Reply #132017-01-14
UOP给定的值是3%~7%,4~6%应该是比较合适的值
Reply #142017-01-15
重整催化剂提升采用氢气,里面怎么可能会有氧气,不怕爆炸?催化剂循环很重要的一点就是反应与再生的安全隔离。
