Stabilized hydrocarbon condensate(HC)from Stabilizer column bottom product to storage, flow meter getting frequent chocking. Flow indication frequently failed and need to rectify by maintenance personnel. This HC having 200 ppm H2O content and with 4~ 6 RVP. With this quality of HC, flow meter lead line getting chocked and reading faulty due to sludge and higher amount of H2O content. How to over come this situation? Should we replace another type of flow meter that can handle sludge material?

Any one face this same type of problem, can share your experience.

 

Thanks in advance.

What type of flow meter are you using?

We are using a vortex technology basically for the same application without any issue.

Pronab,

 

In our Stabilizer we use the Daniel turbine flow meter (1"), we don´t have problems. In our Deburanizer also we use the same flow meter, the clogging problem was resolved with filter installation (type Y).

 

I send you information about turbine flow meter.

 

I hope help you.

Orifice meter is used in this flow meter.

In my opinion, the problem that you are having now is nothing to do with the flowmeter. The presence of sludge in the system is the one your should be thinking on how to eliminate the problem. My suggestion is not to change the flowmeter but install a good filtering system. You need to identify the source of the sludge whether it comes from the feed stream or it is forming in the  stabilizer as a result of polymerization. Most likely it comes from the feedstock especially if the feed stream comes  from a storage.If this is the case then  installing a carbon filter downstream the feed pump is a proper solution because I do not believe that polymerization occurs in the stabilizer.

 

In solving any problem, try to identify the root cause and the right solution is to remove the root cause. Unless nothing could be done to remove it.

 

Hope the above comments triggered the solution to the problem.

 

My two cents regards.
