Requirements for Flare Control and Monitoring Devices

This technical report outlines the requirements for flare control and monitoring devices as mandated by the 40 CFR Part 63 Subpart CC rule from the US Environmental Protection Agency (EPA). It emphasizes the need for petroleum refinery operators to monitor, report, and reduce emissions from flares, which are significant sources of greenhouse gas emissions contributing to climate change. The report details the specific monitoring parameters required, including the net heating value of flare vent gas, and the importance of full speciation of flare gas using gas chromatographs or mass spectrometers. It discusses the advantages of using gas chromatographs for compliance with EPA regulations, highlighting their capability to provide accurate BTU analysis and full composition of flare gas within a 15-minute requirement. The report also compares different technologies for flare monitoring, including calorimeters and mass spectrometers, assessing their cost, maintenance, and reliability in meeting regulatory standards.
