Trinity Consultants, an international environmental firm that specializes in industrial air quality consulting and technology, has partnered with the American Petroleum Institute (API) to update and distribute the API’s SANGEA software.  SANGEA assists petroleum and natural gas companies with estimating, managing, and reporting greenhouse gas (GHG) emissions.  It can also be used to track energy consumption and criteria pollutant emissions.

API selected Trinity Consultants to update the software including these functionalities:

  • Applies API Compendium 2009 for GHG emission calculation methods
  • Incorporates U.S. EPA Mandatory Reporting Rule (MRR) Subparts C, P, W, and Y to comply with regulatory reporting requirements
  • Stores source parameters and operating data through established procedures
  • Calculates direct and indirect GHG emissions as well as criteria pollutants with embedded emission factors and equations
  • Tracks energy consumption and normalizes emissions on a production basis (e.g., ton GHG/bbl of product)
  • Reports GHG emissions to comply with regulatory requirements and/or to track corporate performance metrics

SANGEA calculates and compiles GHG emissions and energy usage data from exploration and production, gas processing, refining and marketing, petrochemicals, transportation, electricity consumption, manufacturing, coal mining, and other activities.

According to Ms. Adebukola Adefemi, Senior Statistical Analyst at API, “The objective of sponsoring SANGEA 4.1 is to provide a user-friendly GHG reporting tool to the Oil & Gas industry and to encourage consistent reporting of GHG emissions.  In 2014, API will continue its annual survey on GHG emissions and criteria pollutants. SANGEA 4.1 will assist the industry in recording and benchmarking consistent and comparable data, and also in analyzing the industry’s environmental footprint.”

Dr. Sue Sung, Director of EH&S Technology at Trinity Consultants stated, “We are pleased to partner with API to update and distribute SANGEA.  The product has been significantly improved to assist environmental professionals with emissions and energy tracking and reporting.”
