2 HOW TO USE THE MOUSE The mouse is a very easy to use way to get the computer to do what you want. These dialog boxes are context specific and employ some combination of character fields, combo boxes, choice boxes and check boxes. All stream and unit operations specifications (input) are accomplished using dialog boxes. Therefore, most input and editing can be done by double clicking or right clicking the object of the operation, as well as by using the menu commands. Use of these help facilities will ease your way through the program. The key provides context sensitive help (place the cursor in a specific field and press the key). The Help command provides access to the On-line Manual, which contains comprehensive technical information.

The bottom line of the screen provides a one-sentence description of the current highlighted item.

There are a series of Help facilities available throughout the program. All should be considered for each problem.

Starting a new job Selecting engineering units Creating a flowsheet Selecting components Selecting thermodynamics options Defining the feed streams Input equipment parameters Running the simulation Reviewing the results Generating hardcopy output The steps do not have to be performed in this order nor do all of them have to be done for each flowsheet.

BASIC STEPS The following ten basic steps are used to run a flowsheet simulation in CHEMCAD. However, for the sake of clarity and for those new to Windows, a review of some of the basic rules for using CHEMCAD is given. It is designed to be intuitive for a chemical engineer familiar with the Windows environment. The input procedure is simple and straightforward. Here we provide a step-by-step description of how to solve the condensate stabilizer problem given below. CHEMCAD is a very easy program to learn, and the best way to master it is by using it.
