Placing Streams and Connecting Blocks

To place a stream:

1 Click the STREAMS icon on the left side of the Model Library.

2 If you want to select a different stream type (Material, Heat or Work), click the down arrow next to the icon and choose a different type.

Move the mouse pointer to the Process Flowsheet window. For each block in the Process Flowsheet window, all ports that are compatible with that stream type are highlighted Ports.

Ports that must have at least one stream connected are shown in red. Other optional ports are shown in blue. If you position the mouse over a displayed port, the arrow is highlighted and a text box with the description of the port appears.

3 Click a highlighted port to make the connection.

If the port is not at the location you want it, click and hold the mouse button on the port. When the mouse pointer changes to the port move shape drag to relocate the port on the icon.

4 Repeat step 4 to connect the other end of the stream. Only those ports that you can connect the other end of the stream to remain highlighted. For example, if you connect a stream to an outlet port, inlet ports remain highlighted but outlet ports are no longer highlighted.

If you have switched off Automatically Assign Stream Names, then you will be prompted for a Stream ID.

5 To place one end of the stream as either a process flowsheet feed or product, click a blank part of the Process Flowsheet window.

If the stream’s source is already connected, then a product will be placed. If the stream’s destination is already connected, then a feed will be placed. By default, if you click a blank part of the window before connecting either stream end, a feed is placed.

6 To stop placing streams click the Select Mode button in the upper left corner of the Model Library:

To cancel connecting the stream at any time, press ESC or click the right mouse button.

To place another stream of the same type, repeat steps 4 through 6.

To place a stream of a different type, repeat steps 2 through 6.
