Used column calculating theoretical plates
Used column calculating theoretical plates
(OP)
Hi
I am looking on the second hand market for a new distillation column to replace a bubble cap 12m height 34 actual plates 20 theoretical.
I am looking for something better, possibly packed. When looking on the second hand market, they never list theoretical plates, how can I calculate this from what data they do give/what data do I need?

RE: Used column calculating theoretical plates
Your existing tower has an overall efficiency of approx. 60% (divide No. of theoretical plates with the No. of actual trays) and this can serve you as a guidance number for rating columns in the market (actual trays X efficiency) - if operating conditions of the tower are more or less the same. Anyway, I'd strogly suggest not to do this tower rating estimation job by yourself; ask for assistance from vendor/consulting companies. I would do it that way.
Best of luck,

So how do I know it is X times better than the current one (which is not hard when current one is rusting away and bubble caps all blocked)?
Contact packing supplyers for there info?
RE: Used column calculating theoretical plates
But, if your existing tower is experiencing severe fouling and corrosion you are maybe looking for culprits in the wrong direction. I don't believe bubble-cap design is the cause of column malfunctioning and chances that internals replacement will solve the problem are very small. This is just based on my experience, I don't know the full story here.
