By my opinion, distillation with low pressure can save energy.
There is no need to heat all water, and there is no need to
waste water for cooling.
If evaporation takes place at, let's say 35oC, there is difference
of temperature of 15-20oC.
In those conditions one can use thermal pump (like
I have read some time before that CaCl2 can be used to dry alcohols
as well as esters.
I am not good in chemistry, but believe that reaction of CaO and HCl
can produce CaCl 2.
Im my country there are many manufacturers of Cao, so I could make it
quite easy.
One more question. Can this salt
