Chapter 1: Tutorial

The Flowsheet Example

In this chapter, we will walk you through the basic steps necessary to simulate process flowsheets such as the following:

Figure 1 - 1: Sample Process Simulation (tutorial.psd)

What You'll Learn In This Tutorial

We show you how to accomplish these tasks in this chapter:

1. Start the DESIGN II for Windows program.

2. Draw the Process Simulation Diagram (PSD) for an Expander plant.

3. Specify Stream Components, Feed Stream Conditions, Equipment, and Thermodynamic Methods.

4. View the Input File has been created for DESIGN II.

5. Calculate the flowsheet.

6. View the results.

This flowsheet is a single stage expansion of a light hydrocarbon stream. First, the feed stream is cooled through a feed chiller(X-1) and any liquids are removed with a vertical separator (F-2). The vapor is expanded (E-4) and liquids separated using asecond vertical separator (F-3). The expander process uses the following equipment:

Start Up DESIGN II for Windows

To start the program: Double click on the DESIGN II for Windows icon in the Main window of the Program Manager. TheDESIGN II for Windows screen displays. The new drawing dialog will show up on the window. Select US mode and thenselect paper size C, then click OK.

Figure 1 - 2: DESIGN II for Windows Screen

NOTE: To exit the program, open the File menu and select Exit. If you have a drawing open, you will be prompted to save itif you have modified the drawing.

You will now have a blank window on which to draw your flow sheet.

DESIGN II for Windows Tutorial and Samples 3

Figure 1 - 3: DESIGN II for Windows Screen

Let's take a look at the components of the DESIGN II for Windows screen:

Windows border/corners

The border/corners are the outside edge of a window; enlarge or reduce the size of a window by dragging on a borderor corner

Title bar

The program and drawing names are displayed here. If you have not named your flowsheet, (Untitled) displays.

Control Menu box

Located in the upper left corner of the window; click on this box to display a menu listing Windows-related functions.You can move, resize, and close a window, or switch to another application. Refer to your Microsoft WindowsUser’s Guide for details.

Minimize / Maximize buttons

Located in the upper right corner of the window; these buttons change the size of the window. The Minimize button(a box with an arrow pointing down) changes the window into an icon. The Maximize button (a box with an arrowpointing up) will enlarge a window to fill your screen. After you enlarge a window, the Maximize button changes intothe Restore button (a box with arrows pointing up and down). Click the Restore button to return the window to its

previous size.

Top Menu

A set of menus pop-up, or open, when you click on the menu name; these menus are File, Edit, Equipment, Specify,Simulate, Text, Options, Size, and Help. These menus list functions you will use to create a flowsheet and executeyour simulation.

The File menu allows you to start a new flowsheet, open an existing one, save, rename, print, etc.

Use the Edit menu to cut/copy, paste, and delete objects.

Use the View menu to redraw the flowsheet or to change the appearance of the main window.

Select equipment symbols to place on your flowsheet using the Equipment menu.

Chapter 1

4 DESIGN II for Windows Tutorial and Samples

Use the Specify menu to enter components, select thermodynamic methods, enter assay data, etc.

View the DESIGN II input and output files, and run the DESIGN II program using the Simulate menu.

Change text attributes such as font and size with the Text menu.

With the Options menu, select to display rulers, a grid, and snap points, or set other options.

For information about a task or function while using the program, select Help. Most dialogs have a Help button; helpmessages are contextual.

Another way to open a pop-up menu is to hold down the Alt key and type the letter in the menu that is underlined.For example, to open the Edit menu, hold down the Alt key and press the E key.

To close a menu, click anywhere outside the menu.

To select a function from a pop-up menu, click on the menu to open it, and then click on the desired function. Thefunction is performed. An option is to drag the highlight down the menu to the desired function, then release themouse button.

Flowsheet area

This is the workspace where you will draw a flowsheet. You can display horizontal and vertical rulers and a grid tohelp you draw the flowsheet. Units of measurements for the rulers and grid are either inches or centimeters.

Scroll bars

Horizontal and vertical bar are used for moving the view of the drawing to the left/right or up/down, respectively.

A scroll bar is made up of arrows on each end, the bar itself, and a scroll box. You can scroll by clicking on an arrowbutton once or continuously, dragging the scroll box to a new position on the scroll bar, or clicking the scroll bar toeither side of the scroll box.

Sheet Tabs

The names of the sheets appear on tabs at the bottom of the flowsheet window. To move from sheet to sheet, clickthe sheet tabs. You can add, delete or rename sheets by right mouse clicking on any of the sheet tabs.

The sheets are named “Sheet1” through “SheetN” where N is the number of the sheet. You can change the name ofthe sheets to any name that you want, up to 40 characters long.

Toolbox

To construct the flowsheet, you add equipment to the drawing area, connect the equipment with streams for materialflow, and add annotations/text/primitive drawing shapes (optional). You can select tools from the Toolbox to performthese activities.

You can click on the tool you want to use, then move to the flowsheet drawing area and use the selected tool.Following are the available tools:

Selection (arrow): Choose this symbol to use the standard tool for selecting and working with objects on theflowsheet, either singly or in groups by region.

Stream (pencil): Select this tool to add streams to your flowsheet.

Text (T): Select this tool to annotate or add text to your flowsheet.

Drawing elements/primitives (arc, line, etc.): Select these tools to add shapes to your flowsheet.

Equipment (categories): Select a category of equipment by clicking on the header name; the related types ofequipment symbols/names are shown. Click on the desired equipment symbol and hold down the left mouse buttonas you drag (move the equipment) onto the desired position on the flowsheet. Release the mouse button when theequipment symbol is in the desired location. To hide the equipment symbols, click the category header na
