Fenceline, Air & Flare Gas Monitoring

Fenceline, Air & Flare Gas Monitoring

Environmental Applications for Real-Time Mass Spectrometer Gas Analyzers

By Chuck Decarlo, Business Development & Marketing Manager

See how the recent updates to 40 CFR 60 and 63 have increased EPA regulation of flare gas and fenceline monitoring requirements is prompting the need to adopt real-time gas analysis solutions at many sites, ranging from oil refineries to downstream hydrocarbon manufacturing.

Industrial mass spectrometers provide fast, continuous updates of the necessary compliance parameters as well as additional information for overall process safety and control. This presentation showed many examples and data from fenceline, flare gas, fuel gas and air monitoring environmental applications using a real-time, mass spectrometer gas analyzer.

Mass spectrometry is an analytical technique that utilizes the molecular mass of substances for identification and quantitation. Gas and vapors are ionized inside a vacuum chamber. The ions are then filtered using electric fields generated by the quadrupole. Ions of a particular mass are selected to go to the detector. The composition of the gas sample is calculated from measured ion current and reported to the user in real-time.

By its very nature, a mass spectrometer is a generalist: there is no class of molecules that is unable to analyze and it’s fast.   Also, if you have to measure 80 or 100 sample points spread throughout your facility that would mean many dedicated analyzers, and all of the required maintenance.  A mass spec can do it all.

NEW O2CX Combustibles Analyzer

New Combustion Optimization Gas Analyzer Launched by Process Insights

A new, compact process, in-situ gas analyzer from Process Insights, measuring both combustibles (COe) and oxygen (O2), provides fast, optimal combustion control for many applications like refining and petrochemical, power, and steam generation, and in furnace and kilns.

Our COSA Xentaur O2CX allows the process to operate safely with a lower excess air ratio, which translates into higher fuel efficiencies. With greater accuracy and sensitivity below 10% O2, the O2CX doesn’t require dilution air, unlike others.  Measuring combustible gas components, oxygen and COe, reliably minimizes safety issues.  Measuring in-situ directly has many advantages and is ideal for process heaters, steam boilers, thermal oxidizers, and furnace optimization.

In addition, installation and service is easy, as the flow guidance tube design allows the sensors to be located near to the back of the transmitter, making for service and maintenance without the need to remove the entire assembly from the stack. The probe provides for both direct and continuous dual readings of oxygen and COe.

The COSA Xentaur O2CX is also versatile for various mounting requirements or difficult applications, including high temperature, dust, or hazardous installations.

Jim Belanger, VP Sales and Marketing – Americas, Process Insights said “Enabling engineers and plant operators to access these previously unachievable air levels is a significant benefit. Combined with improved sensors, superior design and better combustion performance, the COSA Xentaur O2CX gives our customers continuous, reliable gas measurements with greater accuracy and lower maintenance costs.”
