Using condensation as a separation mechanism?
Using condensation as a separation mechanism?
(OP)
A vapor process stream that I am working on is primarily acetone, with small concentrations (< 5 %wt) of Hexamethyldisilazane (HMDS) and ammonia. Acetone condenses around 57 C and HMDS condenses at 126 C. Is it possible that placing two condensers in series, one to condense HMDS then the second to condense Acetone, would yield pure acetone? I want some professional advice on this before attempting to design the condensers. I can not find a VLE diagram for the mixture, as HMDS is rarely found in industry.
Thanks,

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.

Close enough to be pure? 99% acetone. Maybe.
Do some ideal, constant relative volatilitty flash/condensation calculations and see.
Good luck,
