Workshop
The Getting Started module introduces you to some of the basic concepts necessary for creating simulations in HYSYS. Some of the things you will learn from this module are:

• • • •

Methods for moving through different environments Selectingproperty packages and components Adding streams Attaching utilities

You will use HYSYS to define three streams. You will learn how to determine the properties of these streams by using the Property Table utility.

Learning Objectives
Once you have completed this section, you will be able to:

• • • • •

Define a Fluid Package (Property Package and Components) Add Streams Understand FlashCalculations Attach Stream Utilities Customize the Workbook

Building the Simulation
The Simulation Basis Manager
HYSYS uses the concept of the Fluid Package to contain all necessary information for performing flash and physical property calculations. This approach allows you to define all information (property package, components, interaction parameters, reactions,tabular data, hypothetical components, etc.) inside a single entity. There are three key advantages to this approach:

• All associated information is defined in a single location, allowing for easy creation and modification of the information • Fluid Packages can be stored as a completely separate entity for use in any simulation • Multiple Fluid Packages can be used in the same simulation;however, they are all defined inside the common Basis Manager.
The Simulation Basis Manager is a property view that allows you to create and manipulate every Fluid Package in the simulation. Whenever you begin a New Case, HYSYS places you at this location. The opening tab of the Simulation Basis Manager, Fluid Pkgs, contains the list of current Fluid Package definitions. You can use multiple FluidPackages within one simulation by assigning them to different flowsheets and linking the flowsheets together.

Getting Started

Inside the Current Fluid Packages group, there are a number of buttons:

• View - this is only active when a Fluid Package exists in the case. It allows you to view the property view for the selected Fluid Package. • Add – allows you to create and installa Fluid Package into the simulation. • Delete – removes the selected Fluid Package from the simulation. • Copy – makes a copy of the selected Fluid Package. Everything is identical in the copied version, except the name. This is useful for modifying fluid packages. • Import – allows you to import a predefined Fluid Package from disk. Fluid Packages have the file extension.fpk. • Export – allowsyou to export the selected Fluid Package to a disk. The exported Fluid Package can be retrieved into another case, by using the Import function.
You can use the hot key to re-enter the Simulation Basis Manager from any point in the simulation or choose the Enter Basis Environment button from the button bar.
