application software


We are designing new training sessions (Winter/Spring 2017) for AERflare-incin and ABflare.


Thank you to those who participated in the feed back survey for the design of the training sessions.

AERtools is a collection of spreadsheet and application programs created for air quality professionals for the calculation of source parameters and ground level concentrations.  The tools were created based upon state-of-the-art engineering considerations of thermodynamics, energy balance, mass balance and practical application of these principles for use with current air dispersion models and methods.



AERflare-incin is the current evolution of ERCBflare and ERCBincin tools.  This tool functions as a stand-alone MS Excel spreadsheet server and database.  The tool accepts user inputs and generates air dispersion modelling source inputs for the U.S. EPA AERMOD dispersion model and steady state source parameters for the CALPUFF air dispersion model.   AERflare-incin can be used to create AERMOD ready input files or can be used as a server to run AERMOD in screening or refined modes and interpret the predictions for Alberta regulatory ambient air quality compliance and well test flaring/incineration applications.  The goal in developing AERflare-incin was to ensure a consistent content, required contents and quality of air quality modelling, reports and applications to AER (Alberta Energy Regulator)  and AEP (Alberta Environment and Parks).


ABflare was developed as a sister tool to AERflare-incin.  Whereas AERflare-incin was developed for screening and refined air dispersion modelling for AERMOD, ABflare was developed for refined dispersion modelling for time-varying source parameters of flare sources for the CALPUFF model.  As a part of the ABflare model development, the CALPUFF model was extended to extend the source types from point, line, volume and area sources to include a flare source.  The flare source in CALPUFF is a time-varying (arbitrary input) file allowing the time variation of height, diameter, velocity, temperature and location of the (effective) point source.  The ABflare tool is used to create the time-varying input file as well as act as a server to assist the creation of CALPUFF input files and assessment of output from this type air quality analysis.  The ABflare tool can be used to create CALPUFF and AERMOD input files.


AERflare-incin v2.09.170801

This version of AERflare contains the latest features and bug repairs.  Some of the features may still contain bugs and we appreciate hearing about all suspected bugs, odd behaviour or suggested improvements and features.



spreadsheet only (updated 2017-Sep-15)

  • Corrects external link error “personal.xlam” (updated 2017-Sep-14)

  • Corrects output for H2S for RBC and Climit; which always returned 100th value.  This bug was introduced as part of the 170801 version.
  • minor cosmetic fixes (updated 2017-Aug-02)

  • Corrects 'Function not available to you' message when selecting Permit/Application or Flare/Incinerator on the iSTART page (updated 2017-Aug-02)

  • Corrected broken link (updated 2017-Aug-01)

  • Corrected issue relating to the appearance of a virus (there wasn't a virus)
  • Added option for batch mode operation to export the plottable data results from oAERSCREEN page
  • Added processing to the oPROCESSING page to 'Add' a secondary modelling results to the the flaring.  When modelling flares, the control setting NOSTD must be used when using the pseudo-parameters.  For other sources NOSTD should not be used.  Therefore, flares must be modelled separately from other sources.  In Alberta, non-routine, upset and emergency flares are not modelled with other cumulative emissions.  For routine flaring, flare emissions should be included with other emissions.  If the dispersion modelling uses the same receptor grid, the output POSTFILE data time series can be added.  The 'Add' switch allows the user to specify a POSTFILE output results for other sources which is added during run-time processing to form a cumulative concentration.
  • Updated oMODELLING page to list real-source parameters and pseudo-source parameters.  Added emission factors and emission rates of non-sour components.
  • AERflare-incin now uses the newer format GeoTIFF for DEM rather than the older CDEM (no longer supported).  The iBIN page is updated with the link to the new downloads.  The GeoTIFF files are larger but processing them is a little bit faster.
  • Bug fixes for Emissions Factors
  • Bug fixes for Engine/Boiler/Heater calculations
  • Updated code for downloading from the internet
  • Added BC MOE foliage damage post-processing calculations
  • Added Ont. MOE methodology for variable heat radiation losses with changes in flared gas MW.
  • Added daily 1h maximum calculation as an alternative to maximum hourly average concentration.
  • Added 24h and annual average calculations
  • Added high-pressure fuel flare-assist.  This flare-assist adds fuel additional fuel at high co-flowing momentum
  • Updated the flare air-assist calculation to account for air required.  Thus air-assist is assumed to replace stoichiometric air until satisfied.  Air-assist greater than stoichiometric will then degrade combustion.
  • revised presentation of oSUMMARY to avoid broken links issues.
  • Small bug fixes (updated 2017-Jan-15)

  • Corrects 64bit declaration (updated 2016-Nov-01)

  • Corrected broken links on oSUMMARY page (updated 2016-Oct-28)

  • Corrected printout on iTERRAIN, where Row 80 of the page could be over-written if the contour interval was low.
  • Corrected printout on iTERRAIN of xyz-distance, where the start index in the contour data array could be calculated incorrectly depending upon the final contour interval
  • Corrected iBATCH save of DEM_OUT (rows 56-80, exclusive of flare 0,0), instead of (rows 55-79, inclusive of flare 0,0). (updated 2016-Oct-27)

  • Windows 10 Update KB3199209 leads to crash of Excel when AERflare-incin is loaded. (updated 2016-Sep-22)

  • Corrected missing calculation for Qmin flammability check for air assisted flaring.
  • Corrected bug affecting selection of Incinerator source type dropdown and creating an error message “cannot write to protected area”.
  • conditional formatting corrections
