Flare Gas

Increased emphasis on protecting the environment and evolving regulatory guidelines, such as 40 CFR Part 60 Subpart Ja and the RSR, 40 CFR Part 63, are driving industry to improve its processes to be cleaner and more efficient. 

The MAX100-BTU measures the full composition of refinery flare vent gas in seconds, and reports the Net Heating Value (NHV) with accuracy better than ± 1%. 

For dual compliance with RSR NHV and Subpart Ja sulfurs, the MAX300-RTG offers a single-analyzer solution for refinery flare gas monitoring.

A new Broadly Applicable Alternative for mass spectrometer RSR QA has been approved by the EPA. Get the new EPA Alternative Here.

Extrel Environmental Gas Analyzers are ideal for analyzing flare gas streams for H2S, Total Sulfur, BTU, and other contaminants. Extrel systems offer critical information for root cause analysis, and provide customers with the solution needed to analyze output and meet regulatory requirements.

EPA has approved Subpart Ja daily validations that use standards with <300 ppm H2S.
