We are designing new training videos for AERflare-incin and ABflare. We are working preview and subscription services to host the videos.
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.
This version of AERflare addresses several updates including reports from virus protection software of potential malicious activity.
Some of the features may still contain bugs and we appreciate hearing about all suspected bugs, odd behaviour or suggested improvements and features.
AERflare.v210.180216.zip (updated 2018-Feb-16)
- Corrected bad warning message regarding inputs not matching outputs.
AERflare-incin.v210.180215.zip (updated 2018-Feb-15)
- Corrected bad write of data to parallel assessment on oAERSCREEN with zeroes. This corrects a false warning message of apparent minimum data requires on the oSUMMARY page
AERflare-incin.v210.180209.zip (updated 2018-Feb-09)
- Corrected/adjusted warnings and messages on the iSOURCE and oSUMMARY page to match the change in output method (text YES/NO/PASS/FAIL vs radio buttons). Several messages adjacent to PASS/FAIL results on oSUMMARY were not displayed appropriately resulting from previous changes in buttons and may have caused some confusion. Sorry. Added highlights for faster review of issues that may require further documentation for applications.
- Added the display of potential issues raised on oSUMMARY to general red flags
- Added default notes to the iNOTES page.
- Added Run flags and source orientation to the recalculation required lists on oAERSCREEN
- Set the axis divisions to auto on the figure on oBLOWDOWN so that the figure adjusts to all sorts of inputs
- For permits, added a new figure page to display the AER_FIGURE4 flow chart with decision points from the entries.
- Corrected UTM zone bug when entering Geographical coordinates on iSOURCE page then making calculations on iTERRAIN or iUSERTER pages
- Changed coding avoid false-positives of malicious or suspicious activity during virus scanning when sending by eMail to AER. Removed dead code. Changed coding practice of saving settings to registry to a method that saves settings to a file on windows temp folder. A file “AERTOOLS_Settings_AERflare.ini” is created to save inter-session settings such ViewTechnicalPages, iBin Settings, etc. Each time you open a spreadsheet, it will check if the INI file exists, and if so, it will refresh the settings in the workbook being loaded. If the INI file does not exist, then the workbook will create the file as required to save your settings.
- Changed the name of the oCALCULATIONS page to oCALCFLARE.
- Added warning flags to the top of oBLOWDOWN page
- Corrected auto-scaling issues on oBLOWDOWN figure 1
- (Beta Testing) Unlocked the ONT MOE variable radiation heat loss method (see mvarrad on iSTART) which uses the Ont. MOE method to adjust heat loss as a function of flared gas molar mass.
- (Beta Testing) Unlocked the oFOLIAGE processing page. This page is used for analyzing SO2 damage to foliage as part of MOE BC assessments. This page works with saved data and is a post-processing option.
- Added orange shading (warning) to fields on oSUMMARY page. Highlighted the Number of potential issues raised and number of non-default settings (top right of page) for reviewers.
- Corrected incorrectly dimensioned matrix when loading sources.csv and creating a receptor grid.
- Corrected mismatched receptor grid when loading sources.csv file.
- Adjusted entry of HEATER/BOILER efficiency entry; entered on iSOURCE page. Stack losses for heaters and boilers may be calculated on iENGINE page but is manually entered on the iSOURCE page
- Added POINT, POINTCAP, POINTHOR stack types to iSOURCE input page for incinerators, boilers, heaters, engines
- Adjusted Engine energy balance exhaust calculations. Calculations now use the engine specs as a starting point for heat loss at end of engine (may include muffler) and then adds 15% heat loss through stack.
AERflare-incin.v209.170915.zip (updated 2017-Sep-15)
- Corrects external link error “personal.xlam”
AERflare-incin.v209.170914.zip (updated 2017-Sep-14) -- archived
- 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
AERflare-incin.v209.170802.zip (updated 2017-Aug-02) -- archived
- Corrects 'Function not available to you' message when selecting Permit/Application or Flare/Incinerator on the iSTART page
AERflare-incin.v209.170801.zip (updated 2017-Aug-02) -- archived
AERflare-incin.v209.170801.zip (updated 2017-Aug-01) -- archived
- 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
