Process simulation is used to analyze single unit operationsas well as their combination to complex processes.
The obtained mass, energy, and exergy balances give insightinto interdependencies of different process steps.
The simulation results are valuable for design, improvement,optimization, and scale-up of processes.
The objective is to provide the background needed by thechemical engineers to carry out computer-aided analyses oflarge-scale chemical processes.

Equation Oriented Approach : All the equations of the whole process arecollected and solved as a large system of nonlinear algebraic equations.
Modular approach, each sub-model in the process, e.g. a unit operation,is considered a black box, and recycles are solved by an iterativeprocedure.
To perform process simulation using a process simulator Convert from a process flowsheet to a simulation
flowsheet, i.e., replace the process units withappropriate simulation unit.
Model and solve the process unit equations asubroutine is written for each process unit.

EOS based model setsFor EOS based model sets, vapor and liquid phase will use thesame equation of state.The following properties are based on the equation of state:compressibility factor, fugacity, enthalpy, entropy and vapordensity. The following model sets are available: Peng Robinson : uses the Peng Robinson Equation of State for
the vapor and liquid phase. Soave Redlich Kwong : uses the Soave Redlich Kwong Equation
of State for the vapor and liquid phase.
