USA EPA Method 2B Explained: Vapor Incinerator Flow Rate Determination

A comprehensive overview of USA EPA Method 2B, the regulatory standard for determining exhaust gas volume flow rates using the carbon balance method. Unlike other Method 2 variants that rely on physical pitot tubes or inline meters, EPA Method 2B uses a chemical approach. It is primarily applied to gasoline vapor incinerators to determine flow rates based on the carbon content of the influent and effluent gases. In this tutorial, we break down the chemistry, assumptions, and mathematical formulas required for compliance. 📌 What You'll Learn: • The underlying theory of the Carbon Balance Method • Core applicability: When and why Method 2B is required • Required data inputs (CO, CO2, and THC concentrations) • How to calculate the exhaust gas volumetric flow rate • Crucial QA/QC steps and source testing assumptions If this chemical approach to flow rate measurement made sense to you, please give the video a like, drop your emissions testing questions in the comments, and subscribe for more specialized source evaluation tutorials! #EPAMethod2B #CarbonBalance #StackTesting #VaporIncinerator #EnvironmentalEngineering #AirEmissions
