1. Simulator objectives

The main objectives of process simulators are as follows:

• solve material and energy balance equations for all process equipment;

• calculate the characteristics (flow rate, composition, temperature, pressure, physical properties) for all fluids flowing between the devices;

• provide the information needed to size equipment, such as heat exchange quantities or internal column flow rates.

In addition to these objectives, there are :

• estimated investment and operating costs and, in the context of sustainable development, the impact on the environment and safety;

• optimization of process operating conditions.
