Figure 3.3 shows a frequent mistake that is made when defining the compositions. The oxygen
(O2) component is set to 1.0, but the remaining components are undefined.

Using a Composition in a Stream
In PSE, you can define a composition for each gas stream inyour process. However, instead of
defining the used composition for each gas stream separately, you can also define or set one
composition object for a group of gas streams. In this case, all streams selected will use the
same composition (the composition does not change).
Defining a Composition for a Single Stream
⇒
To define the composition that is used in a stream:
1.
Double click on the stream. PSE opens the window for editing the data of that stream.
2.
Select in the composition field the composition that you want to use.
