API Releases SANGEA 4.1 for Standardized GHG Emissions Reporting

Since the early 2000’s, the American Petroleum Institute (API) has supported the SANGEATM software tool for petroleum, natural gas and petrochemical companies to quantify greenhouse gas (GHG) emissions and to standardize emissions reporting.  Regulatory changes, including mandatory reporting requirements for GHG emissions, prompted API to sponsor a major overhaul of the software including current calculation methodologies. As announced in the Summer 2012 issue of Environmental Quarterly, API chose Trinity Consultants to develop its SANGEA-4 software. The free Beta version 4.0 was released in 2012 and the final version SANGEA 4.1 is now available.

SANGEA-4 is a desktop database program with a user-friendly interface that can be used to manage various types of emission sources throughout a large entity for corporate performance and/or regulatory reporting requirements. In order to build a solution that would promote long-term software usability and easy maintenance, the new product replaces a spreadsheet-based application with a Web-based product that uses a Microsoft .NET framework and Access database files for source information storage. 

SANGEA 4.1 provides calculation methodologies in various modules based on API’s Compendium 2009 and corresponding subparts of U.S. EPA’s Mandatory Reporting Rule (MRR) for GHG emissions. The new software includes emission factors for criteria pollutants that enable users to quantify emissions for both GHG and criteria pollutants in one tool. SANGEA can also be used to track energy consumption and normalize emissions on a production basis (e.g., ton GHG/bbl of product). The information from SANGEA may be used for API GHG benchmarking studies and to comply with Federal GHG emission mandatory reporting rules for the petroleum and aligned industries.

The reporting entity hierarchy applied by existing SANGEA users is retained in SANGEA 4.1, including the reporting entity, location group, location, and source set up process, with extended steps to incorporate more source specific requirements under multiple protocols. Sources are configured for a specific location. Multiple locations/ location groups can be created under one SANGEA 4.1 working file (i.e., a Microsoft Access database file), which allows companies to report emissions by business operation groups, geographical regions, or regulatory reporting entities.Figure 1 provides a typical reporting entity hierarchy structure that can be established in SANGEA 4.1.

SANGEA 4.1 integrates two GHG reporting protocols with numerous source types. Table 1 shows the available source “modules.”  Within each module, wizards help users set up emission sources and multiple calculation methods for the protocols. The software guides users to specify source parameters that are needed for GHG emissions calculation and/or reporting requirements.  These source parameters are stored in the source database for future emission inventory reports. SANGEA 4.1 also offers a “User Defined Sources” module under the API Compendium 2009 that allows users to define sources that are not already established in SANGEA.

There are many user-friendly editing functions in SANGEA 4.1 that allow users to easily manage sources, such as:

  • Gas composition property and API gravity calculations.
  • Source import and export tools for Stationary Combustion - allows users to edit many combustion sources in Excel spreadsheets then import into SANGEA 4.1.  Source parameters can also be exported to spreadsheets for use in other applications such as EPA’s MRR reporting tools.
  • For each new reporting year, users can copy from an existing report file - this function copies all source parameters from the existing file and removes all activity data that should be updated for the new reporting year.
  • Default emission factors are automatically selected for specific fuels or sources and can be checked for reference at the “Tools” menu.
  • “Subpart W Reporting Requirement by Industry Segment” is listed for easier reference for applicable emission sources.

SANGEA 4.1 is available from API for organizations in the petroleum and other applicable industries. Ms. Adefemi, Senior Statistical Analyst at API stated that, “The objective of sponsoring SANGEA-4 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 will assist the industry in recording and benchmarking consistent and comparable data, and also in analyzing the industry’s environmental footprint.” Many large oil and gas companies have adopted SANGEA for corporate GHG reporting requirements.  To purchase  a copy of this software, visit api-sangea.org.

SANGEA-4 development is led by T3, a division of Trinity Consultants that implements EH&S information management solutions (EMIS), with commercial software development expertise from the BREEZE software group. T3 has over 15 years experience developing custom software and implementing EMIS solutions in myriad industries.
