When components of a mixture have very similar Boiling Points, say 2 C is distillation ever a viable separation procedure at industrial scale?
Assuming one were willing to install a very tall column, say 100 theoretical plates (which with modern high efficiency structured packing can be fit within a column 15-20 m tall), would one expect distillation to work out?
The goal is to get an impurity component to approx. 0.1% starting from a 1.5% initial concentration. The rest of the mixture is the desired product & the BP difference between the two is only 2 C.
