You can set emission limits for the various pollutant categories, except for volatile organic compounds (VOCs) through the Emission Limits Dialog. To access this dialog, do one of the following:
● click on an empty area on the flowsheet and then click Process Options } Preferences } Emission Limits on the Edit menu, or
right-click on an empty area on the flowsheet to bring up its context menu and click Preferences } Emission Limits.
The emissions of VOC components are calculated by the program based on the composition of the various vent (emission) streams. The Emissions Report (EMS) will include warnings if the accumulated emissions for any of the categories included in the above dialog exceed the specified limit.
Through the same dialog you can introduce four additional used-defined pollutant categories and specify their limits. Once a user-defined pollutant category has been introduced, you can classify any component present in this process file as contributing to that category; for more details, see Pure Component Properties.
