    New Test Method for Determination of Flare Efficiency using Narrow Field Passive Fourier Transform Infrared Spectroscopy

    (What is a Work Item?)

    Developed by Subcommittee: D22.03 | Committee D22 | Contact Staff Manager


    1. Scope

    1. Scope 1.1 This method describes the procedures for determining the combustion efficiency of flares using Passive Fourier Transform Infrared Spectroscopy and applies only to narrow field PFTIR instruments as defined herein. 1.2 This method cannot be used for the determination of speciated concentrations of flare plume components nor can it be used for determining mass emissions from a flare. 1.3 Units - The values stated in SI units are to be regarded as standard. Other units of measurement are included in this standard for informational purposes only. 1.4 This method describes the equipment and operating procedures for measuring flare efficiency, and procedures for calculating results. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish safety and health practices and to determine the applicability and observe all regulatory limitations prior to use.

    EPA is currently requiring flare testing using Passive FTIR and there is no established test method available.
