hey mate thanks you so much for your information and help to me so much, so yes I'm trying to design my continuous still and I'm investigating and working in that, yes I have been reading about that still and it has a calandria inside of dymethalizer to do that process, I have one question more, do you recon his C1 its a big calandria and that its the secret of they got that product, are 14 sieve trays with a pipe in the middle which work as big calandra to pull down the condensate, pushing up the ethanol, or its just 14 sieve trays as normal stripping column. and the real work its just done by dymethalizer.
