Phenol and acetone, in a ratio the chemistry fixes
Cumene peroxidized in air then acid-cleaved, with acetone, recycle cumene, phenol and heavies separated across three columns.
The actual dark-mode canvas: cumene peroxidized in air, the off-gas flashed away, the hydroperoxide acid-cleaved, then acetone, recycle cumene, phenol and heavies separated in three columns.
One feed, two products, a fixed ratio
Cleavage produces phenol and acetone mole-for-mole, so a phenol producer is an acetone producer whether it wants to be or not — the classic co-product economics of this route. Both steps are atom-balanced here, so that ratio falls out of the chemistry rather than being asserted.

Stream oxidizer temperature, cleavage acid rate and each column's cut from the plant's OPC-UA server into this flowsheet's twin comparison — peroxide concentration is the safety-critical variable here, and it is set by the same balance the flowsheet solves.
