The HRVOC GC system is designed for analytes recently targeted by the Texas Commission on Environmental Quality (TCEQ). Ethylene, propylene, 1,3-butadiene and butenes have been found to contribute to high ozone observed in the Houston area. It is believed that substantial emission reductions of these four compounds are likely to have a high impact on the rapid ozone formation and transient high ozone in the area. To that end, the TCEQ requires that facilities in the Houston/Galveston area with a vent gas stream, flare or cooling tower heat exchange system that emits HRVOCs (or has the potential to emit HRVOCs) continuously monitor their systems for composition and flow.
The chromatograms above are from an HRVOC GC system equipped with FID and PID detectors. The sample was 20ppb C2-C6olefins + 1,3-butadiene. The sample gas stream was trapped with the CryoCooled Peltier Trap at -10oC for 20 minutes.
