TankESP (tank calculation)

TankESP is a tank emissions calculation software product suite that uses the emission estimation procedures from Chapter 7 of U.S. EPA’s Compilation of Air Pollutant Emission Factors (AP-42) for volatile organic compound (VOC) emissions from storage tanks.

TankESP is widely regarded as the most accurate tank emission calculation tool in the market because it was designed by Rob Ferry, one of the authors of AP-42 Chapter 7.1 and American Petroleum Institute (API) documents 19.1, 19.2 and 19.4.
