Coking fractionation tower
Thread Content
Let's discuss it: Should the bottom circulation pump of the coking fractionation tower be equipped with two filters? How often does it take to clean?
There is no need for two! With frequent cleaning, the effect of one filter can meet the requirements. If two filters should be blocked, they must be blocked. The filtering effect is not 1+1=2, which is a waste of resources. Clean once a month (except cleaning if blocked)
Our company has a special circulating oil filter for the circulating oil at the bottom of the coking fractionation tower. There is also a filter in front of the circulating oil pump. During normal production, it is cleaned once per production cycle.
Just use one normal line, and use the secondary line when cleaning. We now use radiation pumps with bottom circulation instead of bottom circulation pumps. The bottom circulation filter is sometimes cleaned several times a month, sometimes once every few months. It is not fixed and depends entirely on the actual situation.
If there is only one, take the secondary line when cleaning the filter, then the coke will enter the pump and furnace.
Stopping the pump for a short time when cleaning the filter should have no effect! Aren’t there heat traces on the pipelines? How can your cycle still enter the furnace? Coke powder can be found everywhere. Don’t think too ideally about the bottom of the tower. There is still a long way to go to solve the problem of oil coke powder at the bottom of the tower: lol
Personally, I think we should set up two filters, one on and one on standby, so that we can not only continuously clear the focus but also avoid running secondary lines. This is especially useful in the early stages of work or when the operation is unstable. Another benefit is that the results are more obvious when the pump is repaired. Adding an extra filter is not expensive and the most important thing is to ensure production.
It is enough to install a filter in the bottom circulation of the coking fractionation tower of the Beijing Institute process, and there is another pump inlet. When cleaning the filter, you can also use the auxiliary line, or you can stop the bottom circulation system for a short time. It seems that the Luoyang Hospital process cannot be deactivated. Hui Lian's design has the circulation filter at the bottom of the tower inside the tower, so there is no need (and no way) to clean it. This post was last edited by Bai Ding on 2009-4-20 14:30 ]
Our tower bottom circulation pump is set to one, but there are two filters. Because the start-up time is short and the number of cleanings is small, it cannot be evaluated.
Our installation uses the Luoyang Institute process. There are two circulating oil filters, one on and one on standby.
I agree with using two. . . It doesn't cost much. . . After all, you can switch to use it at any time. . . :lol
