Ethanol distillation design
Thread Content
Which type of tower is better for ethanol distillation design? Why? Thank you to all the experts for helping with the solution
What is the concentration of the mother liquor? What concentration should it reach – anhydrous or 95% v/v?
I am interested in designing a bubble column to purify industrial alcohol into pharmaceutical-grade alcohol; the process is simple, but I’m not sure how to deal with azeotropic mixtures. Do you have any suggestions? Thank you
The mother liquor is edible alcohol, which is purified to become pharmaceutical alcohol using a bubble column – what are the things to keep in mind? ? Thank you all for your advice
Stop using bubble columns; they are expensive, and their operation requires a high degree of flexibility as well as presents significant challenges. Bubble columns are not used very often these days. It is recommended to use high-efficiency packed columns, as the separation task is not that difficult
The packing is indeed good, but our factory thinks the cost of packed towers is a bit high. What do you think about using floating valve towers?
So which filler do you think is more cost-effective?
Packed towers are the mainstream option; floating valve trays result in higher pressure drops and less operational flexibility compared to packed towers. For ethanol separation towers, both plate corrugated fillers and wire mesh fillers can be used. If your material is not dirty, using a packed tower is simpler
