Process Description:

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

The volume and initial amounts of the two reactants might be varied from the stated values of $500L,$

$120$ moles and $120$ moles respectively. The maximum solubilities for A and $B$ in ethanol at $50C$ are

given on the previous page.

Hint: One approach would be to write down the equation for the throughput per $24$ hours, but

allowing the solvent volume $(V)$ to vary rather than this being fixed at $500L.$
