BRE 121: Air Emissions

Introduction to Air Emissions and Process Simulation

Upcoming Sessions

8/19/2024 - 8/20/2024Austin - TX - USA
12/11/2024 - 12/12/2024Midland - TX - USA


Formerly named Level 1-Air Emissions, this course is designed to provide insight into the use of ProMax® to calculate air emissions. VOC emissions, BTEX calculations, Working & Breathing, Loading, and Flash losses are all covered. The process sites discussed include liquid storage tanks, flares, well sites, dehydration units, and compressor stations, with particular emphasis on the calculation, reporting, and reduction of VOCs, BTEX, GHGs, NOx, and working, breathing, and loading losses as defined by the U.S. EPA and AP 42 regulations.

In addition, the basics of process simulation are discussed, along with many of the capabilities and features of the ProMax process simulation software. Several techniques and methods used in developing simulation models and emission reports for plants and facilities will be covered. The course is designed to demonstrate the extent and breadth of benefits ProMax can provide for environmental reporting requirements and applications of process simulation using ProMax through a hands-on implementation.

Attendees will learn:

  • Techniques to estimate air emissions from various processes
  • Applications of the ProMax software to find emissions rates


  • None


  • Instructor-led demonstrations
  • Hands-on simulation
  • Question-Answer
  • Open floor discussion


Installation of ProMax

The first step in all courses is to verify that ProMax is properly installed on each attendee’s computer.

Emissions Calculations Using ProMax
  • Exercise 1: Flowsheet Basics – Introduces the basic concepts of ProMax, including how to draw and configure processes quickly and neatly. Demonstrates methods for displaying process information directly on the flowsheet.
  • Exercise 2: Sample Validation – Discusses the importance of obtaining an accurate sample composition, and how to validate results obtained from a laboratory using bubble point and phase envelope analyses. Also demonstrates how to make basic flash emissions calculations on an oil tank, and introduces the use of several ProMax Property Stencil shapes.
  • Exercise 3: Tank Losses – Expands on the previous exercise by adding in calculations for the working, breathing, and loading losses from a tank. Teaches use of the "Tank Losses" property stencil.
  • Exercise 4: Process Emissions – Teaches how to calculate and reduce emissions rates from amine sweetening and glycol dehydration units. Demonstrates use of the Scenario Tool to perform long lists of calculations automatically.
  • Exercise 5: Linking Flowsheets and Projects - Demonstrates how to link various flowsheets and projects together into a single file. Connects the amine sweetening, glycol dehydration, and flare processes into a continuous chain, as they are in real plants.
  • Exercise 6: Flares – Demonstrates modeling of combustion through reactors. Teaches use of simple specifiers to control certain process parameters as functions of other known parameters.
  • Exercise 7: Back Blending – Shows how to calculate emissions for an entire well site given only the flow and composition of the outlet gas, the hydrocarbon liquid, and the water stream. Applies the concept of back blending and introduces simple solvers to automatically adjust certain process parameters to achieve desired results in downstream operation. Also demonstrates how to automatically populate a report with process information.
  • Exercise 8: Reverse Separator – Shows how to calculate emissions for a tank given only the flow and composition of the outlet liquid, not the inlet stream. Introduces a property stencil to perform this procedure automatically.
  • Exercise 9: User Value Sets – Shows how to model a compressor station and calculate total power requirements for the process. Demonstrates how to create custom variables for user-defined calculations.
  • Exercise 10: Excel Import/Export – Expands upon the previous exercise by illustrating how to calculate emissions from operating equipment (e.g. compressors). Utilizes ProMax®’s ability to import and export variables into Microsoft Excel.
  • Exercise 11: OOOOa Vent Assessment Tool – Introduces the OOOOa Vent Assessment Tool in ProMax, which steps engineers through the required calculations for potentially uncontrolled emissions from tank battery vent systems as per NSPS OOOOa, and helps determine whether vent systems are large enough to handle peak flash gas flows.
Notes About the Agenda:

Our agenda is provided to give the approximate material to be covered in the course, in the approximate order it will be covered. All courses we provide will be tailored to the needs of the host company providing the training accommodations, as well as the needs of the course attendees. Some courses may cover additional topics, while some may cover less than indicated in the agenda.

Some courses may be shortened to one or two days when represented by a three-day agenda. These courses will typically cover both process simulation and process optimization topics, but will exclude several exercises. Please contact our training team here: Contact Training, or through the consulting engineer for your region, for specific information for any course.
