General Description Emission Master is an intuitive software program that enables the user to begin defining a process recipe file immediately. However, the user will normally enter additional information for the process recipe at the Title Page. An instructional animation is available from the internet for creating a new Emission Master recipe file. Once saved, an Emission Master process recipe file may be opened at a later date.
Emission Master is a batch modeling tool that supports several different process activities. Think of them as steps in a recipe . . .
Charge - Charging materials into a process vessel. Transfer - Transferring process material from one vessel to another. Purge/Sweep - Maintaining a nitrogen atmosphere above the batch. Heating - Elevating the temperature of the batch. Depressurization - Preparing for a vacuum distillation or other operation. Vacuum Operation - Aging the batch while maintaining a vacuum. Gas Evolution - Releasing off gases from a chemical reaction. Solids Drying - Drying wet products. Holding/User Defined - Characterize processing activities that have no associated emissions. Combustion - Characterize processing activities that have no associated emissions. Fixed Roof Storage Tanks - Model conventional tank farm operations.
While each process is unique with respect to the chemicals, equipment, and overall recipe, most processes can be broken down into one or more of the above processing steps. The goal of Emission Master is to provide an adequate supply of models that may be collectively used to adequately characterize the process and to calculate the point source air emissions to meet environmental regulatorial objectives.
File management. When the user creates a complete process model he or she may save only the recipe portion of the model to a *.emm file or both the recipe portion and the data records portion as a *.emd file.
