Hello,
can anyone tell me from personal experience (or maybe a rule of thumb), what the maximum allowable velocity in a pipeline for slurry residue oil (with approx. 2% catalyst) from an fcc plant is?
Thank you!
Slurry transport piping design and operation is a little tricky.... Usually, what the engineering challenge involves is finding the best velocity required to efficiently transport solids. The minimum transport velocity is usually important.
This min velocity depends on the percentage solids, density, particle size and several other criteria.
Pipe routing is also very important. There are entire books written about slurry piping design and the study of Rheology
Maximum velocity ??... I would guess that you are looking at erosion/corrosion issues ...
Is the transported material hard ground garnet or talcum powder ?
Thank you for the reply. The temperature is around 200 degrees and the viscosity around 0,8 cP. Indeed, I am concerned about erosion. I think it‘s more like talcum powder.
Thank you!
