Inquiry (采购产品): average distillation column cost Hi, I'm a chemical engineering student at the university of california, berkeley. I was looking for some general cost estimates on distillation columns. is it possible to get a range of cost per stage. I understand teh size of each stage has a huge impact, but a general range that we could take an average of would help, for maybe 20, 30, and 40 stages. thanks for your time. **** Hidden Message ***** Geoffrey Masterson 94704 USA Company: Student E-mail: g.r.masterson@gmail.com **** Hidden Message ***** g.r.masterson@gmail.com
