3. Separator
2-Phase Separator
3-Phase Separator
Why do we need Separation ???
Disperse Phase can have undesirable effects, i.e:
1. Steam which has a little moisture entrained in it can leave undesirable silica deposits on superheater tube
2. Water carried over into turbine from a boiler can erode the blades.
3. Gas carried under into pump from a vessel can erode the impeller.

Distillation
• Distillation process use 40% of energy in a chemical plant.
• The traditional approach for solving distillation columns uses the concept of equilibrium or theoretical stages. This concept assumes the vapor and liquid phases leaving any stage are in thermodynamic equilibrium with each other.

• Function : used when there is a reaction occurs in the process
simulation
• There are 6 type of reactors provided by hysys: 1. General reactors consist of : Gibbs Reactor, Equilibrium
Reactor, Conversion reactor, Yield Shift Reactor 2. Continuous Stirred Tank Reactor (CSTR) 3. Plug Flow Reactor (PFR)
• Before begin the simulation it is important to describe the

Type of Reactor
Can be used when we do not know the reaction sets
Can be used for modelling conversion reactions
Can be used for modelling equlibrium reactions
can be used for complex reactors where no model is available
CSTR Reactor
The CSTR is a vessel in which Kinetic, Heterogeneous Catalytic and Simple Rate reactions can be performed. The conversion in the reactor depends on the rate expression of the reactions associated with the reaction type.
PFR Reactor
The PFR can modelled Kinetic, Heterogeneous Catalytic and Simple Rate reactions.
