What's the ideal vapour speed, in your opinion, for a reflux / compound column? I've read that 20 inches per second is the max desired vapour speed with a mesh packed column for reflux seperation efficiency. But I will have CD bubble sections as well as a packed section when running for vodka.
The reason I ask is that I'm trying to calculate the minimum watts I need to drive a 4" 6 plate CD with a 400mm packed section (total 1105mm + or -). Packing would probably be Amphora copper mesh (claimed to have a good reflux ratio when used as packing).
I'd really like the answer to be less than 3KW, but I'm worried that I'm way short of power. Wish my math was better so I could understand the calculation. Also, maybe I don't need any math and someone will have a reassuring comment / practical guideline. ^:)^
