Fill tank with solution $($ethanol$/$A$/$B$).$ Increase temperature of the feed from $20C$ to

$50C(1$ hour$)$

Reaction takes place isothermally at $50C(4$ hours, to give conversion of $50\%)$

Filtration of reaction solution to give product $P(2$ hours$)$

Drying with hot nitrogen gas followed by the removal of powder product $(3$ hours$)$

Question:

Outline a strategy to allow for the inclusion of a simple Heat Exchanger Networks $($HEN$)$ with

this single equipment unit.
