Natrat Posted March 7, 2014 Share Posted March 7, 2014 I've been thinking a lot about still design, and I was wondering if anyone had ever seen a Petlyuk style column in use for ethanol? We tend to think of our distillations as a binary water-ethanol system, but it's actually a three or 5 or 10 part system if we start to consider the congeners. I think reducing it to a 3 part system (heads-ethanol-water) is most efficient... I was mostly thinking that a large-scale continuous system could use this for a continuous heads draw as well as hearts. anyone seen something like this? Am I way off the mark, or are they as common as dirt in big ethanol plants? Link to comment Share on other sites More sharing options...
