Title Page
A process modeling session is started by highlighting Title Page at the top of the activity list and double clicking or by selecting Update! from the Emission Master's main window menu. A data entry window will appear for accepting basic process information including product name, process step, and the process cycle time.
Data entry items are described as follows:
Zero Stage: Condenser exit gas composition is calculated based on the original batch composition but at the specified condenser temperature. This style calculation was used in versions of Emission Master 6.0 and earlier. Single Stage: Condenser exit gas composition is calculated such that the exit gas is in equilibrium with the exit liquid condensate. Air, nitrogen, or other non-condensable gases are assumed to exit the condenser in the exit vent gas stream.
Initial Composition: The headspace concentration for each compound is made based on the initial composition of the initial vessel contents and the incoming inlet stream. This setting will result in higher emission calculations than the Average Composition setting. Average Composition: The headspace concentration for each compound is made based on the average batch composition during the charging or transfer operation. This configuration generally results in the lowest emission calculation possible since it provides for the basic dilution that occurs during the filling operation through blending of the components in the system.
Once the Title Page has been completed, the process information will be transferred to the upper right description box. This data along with a list of the process activities will be added to the Title Page of the report for this evaluation. As processing steps are modeled and added to an overall evaluation, the Title Page will be updated to reflect the cumulative process.
