•
Selective control. Two cases, case 1 is a compression station control and case 2 is
a pumping station control. Particular interest in the anti reset windup mechanism
is shown.
•
Feed forward control. Temperature control comparative in a heat exchanger with-
out feedforward compensator and with a static or dynamic one.
•
Split range control. This technique is applied to three systems. A pressure control
in a distillation column head, a pressure control in a blanketing and a simultaneous
flow and temperature control.

"Process control units" menu
The “Process control units” modules are (Fig. 1):
•
Steam production boiler. Level and pressure control (ten coupled control loops).
•
Boiler Burner Management System (BMS). A security system to monitor the boi-
ler and execute, in a safe way, all scripts to turn on and off the burners
•
Exothermic chemical reactor. Hydrodesulphurization process control.
•
Endothermic chemical reactor. Catalytic re-forming process control.
•
Furnace. Temperature control (eight coupled control loops) driving two combus-
tibles (fuel and gas).
•
Distillation column. Two control structures and study of the economic and control
aspects integration.
•
Blending. The Blending is a batch process whose aim is to mix different compo-
nents in appropriate proportions to meet a required specification. The simulated
blending manages five components according to a mixture prescription that is de-
fined by the user.
