    Fundamentals of Tank Emission Calculations

    This one-day course covers VOC emission calculation methods based on the algorithms specified in AP-42 Chapter 7 and API Technical Report 2568, November 2007 and some local agency guidance. Mr. Rob Ferry, who has been involved in the development of the emission factors in AP-42 Chapter 7 for more than 37 years, will work with his Trinity colleagues to instruct the course.

    The course provides a detailed look into air emissions from storage tanks and provides insight on best practices for emissions calculations. The equations for estimating routine standing and working losses will be covered for ambient tanks as well as for tanks that are heated and/or insulated. Detailed discussion will also address the estimation of emissions from MSS events (i.e., floating roof landings and tank cleanings). Additional topics include estimation of flashing losses from production field tanks, calculation of maximum short-term (lb/hr) emission rates, determination of effective throughput from liquid level data, and determination of heating cycles. Finally, the course provides recommendations on how to improve tank data quality and the accuracy of emissions estimates, thereby mitigating the potential for regulatory pitfalls.

    The course also reviews the proposed changes to AP-42 Chapter 7 that were posted by EPA on July 25, 2018, and the expected impact of these changes on estimated emissions.

    Tank Emission Calculation Workshop with TankESP Software

    Given the complexity of the AP-42 Chapter 7 methodology for estimating emissions from storage tanks, a software tool is a practical necessity. U.S. EPA’s TANKS 4.09d software was heavily used prior to 2014 but is no longer maintained or recommended by EPA due to numerous calculation errors. In response to the need for a tank emissions calculation software tool, Rob Ferry developed the TankESP software.

    TankESP correctly applies the AP-42 Chapter 7 methodology to estimate routine standing and working losses for ambient tanks as well as for tanks that are heated and/or insulated. TankESP additionally accommodates estimation of emissions from MSS events (i.e., floating roof landings and tank cleanings), calculation of maximum short-term (lb/hr) emission rates, determination of effective throughput from liquid level data, estimation of emissions from heating cycles, and estimation of flashing losses from production field tanks.

    This one day course provides hands-on instruction in the use of the TankESP software. During the course, students will receive step-by-step guidance, beginning with entering routine service data to generate monthly or annual emissions and progressing to entering service changes, floating roof landings and tank cleaning events, and creating custom reports.

    This course includes hands-on exercises requiring the use of a computer. Attendees should bring a laptop or notify the instructor if they are unable to do so.

    Upon completion of the course, attendees are expected to:

  • Set up tanks in TankESP and input routine service data to conduct emissions calculations
  • Create MSS events (roof landings and tank cleanings)
  • Add or modify chemical and stock properties
  • Troubleshoot for improper or incomplete data entry
  • Properly model heated and/or insulated tanks
  • Generate estimates of maximum short-term (lb/hr) emission rates
  • Create customized reports and develop your own templates with different reporting formats
