Process description for the U3 example simulation

The process consists of the following:

• Two external, parallel steam generation facilities provide high pressure steam. The steam generation facilities are not simulated.

• There are three steam levels: high pressure at 4240 kPa (600 psig), medium pressure at 2170 kPa (300 psig), and low pressure at 1135 kPa (150 psig).

• There are two steam turbines, a back-pressure turbine from high pressure to medium pressure and a medium pressure condensing turbine.

• The simulation provides steam to consumers at two locations in the refinery, one at the north end and one at the south end. It provides steam at all three pressure levels in both locations.
