In accordance with SCAQMD Rule 1180, the El Segundo Refinery uses 12 UV Sentry and 12 Air Sentry analyzers to monitor ambient air over roughly 4,000 meters of refinery fenceline. These open path analyzers measure, in real-time; BTEX, SO2, NO2, Acrolein, Formaldehyde, and Naphthalene fugitive emissions.
The Cerex AirSentry FTIR in particular measures fugitive emissions of more than a dozen compounds, including; Acrolein, 1,3 Butadiene, Styrene, Pentane C5, n-Hexane C6, Methane C1, Ethane C2, Butane C4, Propane C3, Formaldehyde, Propene (propylene), Ethene (ethylene), Acetylene, Acetaldehyde, Methanoic Acid, Methanol, Hydrogen Cyanide, Ammonia and Carbonyl Sulfide.
As with other BAAQMD and SCAQMD regulated refineries, all real-time data from Cerex analyzers at the El Segundo refinery is uploaded to a public-facing website – updated every 15 minutes.
