Can a CO2 distillation column use packing?
Thread Content
There is now a CO2 distillation column that requires the use of packing, but the operating pressure of the column is 45 bar. I have never used a filler under such high pressure – does anyone have experience in this area? By about how much will the efficiency of the filler decrease? For example, in the case of a 700Y plate wave, how many theoretical plates are there per meter at this point?
The pressure is too high; a plate tower would be more suitable
I’ve never seen a tower with such high pressure. Looking forward to a reply from experts.
I have seen CO2 distillation columns designed for 4 MPa.
Is a tray or a packing used at 4Mpa?
In my opinion, the relationship between the seasoning used and the plate and pressure isn’t that significant; what’s important is the flow rate specified in the design as well as the requirements for distillation. As long as these needs are met, along with the requirements related to the use of packing materials, then such packing can be used – especially structured packing, which can significantly reduce the height of the equipment! Our distillation tower, 58 kilograms, and also packing!
Personally, I think trays are better
It is said that the cost-performance ratio of plate towers under high pressure is better than that of packed towers, but this has not been carefully examined...
