Emission Model of Industrial Sources (EMIS)

The Emission Model of Industrial Sources (EMIS) program is a tool for estimation, analysis, and reporting of facility emissions. Using basic process data, EMIS provides emission estimations for stack, fugitive, and storage tank sources. This process data can be obtained from measurements, or directly imported from thermodynamic simulations such as ChemCADTM or Aspen Plus. The emission estimation methods include CMA’s SOCMI and Leak/No Leak emission factors for fugitive sources, and the EPA AP-42 TANKS algorithm for storage tank working and breathing losses. Included are various graphical analysis tools for sensitivity analyses of process parameters, such as specific operating conditions, emission control, and emission factors. Detailed emission results may be written to an external file for further analysis, compliance report requirements, or as input into a transport and diffusion model. EMIS was developed in Java, which is platform independent, and relies on an Oracle database for data management
