ENV-10-24 Performance Evaluation of a Steam- Assisted Flare at High Turndown Using Passive Fourier Transform Infrared Spectroscopy

Description:

As required by a Clean Air Act Section 114 request requiring testing of a refinery steam assisted flare, Marathon Petroleum Company (“Marathon”) conducted performance testing of its main flare in Texas City, Texas. The main objective of the test was to better understand the impacts of steam on the overall emissions performance of the flare in terms of combustion efficiency (CE). Marathon has implemented an automatic steam control system for this flare designed to mitigate periods of flare over-steaming. The performance test was conducted using a Passive Fourier Transform Infrared (PFTIR) Spectroscopy instrument developed and operated by Industrial Monitor and Control Corporation (IMACC).
