Formaldehyde reactor control.
Multitubular reactor, Fe-Mo catalyst, 10,000 tubes. The Process deck shows the reactor along the tube, its safe operating window, pressure drop and catalyst ageing, with setpoint recommendations. The Business deck values operation and the catalyst change at current prices.Layout for the DataCards build · simulated plant data · placeholder kinetics, limits, ageing and prices · not for operation

Goal and constraints
Main goal of the recommendation
The recommendation also values catalyst life: a lower hot spot slows molybdenum loss and the pressure-drop rise.
