Process Mass Spectrometers in Petrochemical and Chemical Processes

Optimize production with gas analysis

Fast, accurate, comprehensive gas analysis data enables model predictive control systems to be updated in real-time, resulting in production unit optimization and maximum profitability. Hydrocarbon processing plants around the world use process mass spectrometers to optimize a diverse range of chemical production processes as well as to monitor fugitive emissions.

Process mass spectrometers offer complex sample stream analysis in seconds, automatic calibration, minimal maintenance, no required carrier gases required and few utilities.

Petrochemical/chemical production categories

Air monitoring: Benzene, Toluene, Ethyl Benzene, Xylenes, Vinyl Chloride, Ethylene Dichloride

Select a monitoring method that meets the accuracy and precision requirements of the prevailing standard.

Natural gas processing

Accurately analyze the calculation of calorific value (gross and net), density, specific gravity, Wobbe Index, stoichiometric air requirement and the combustion air requirement index (CARI).

Ethylene furnace optimization

Minimize costs by eliminating the need for hydrogen fuel or helium carrier gas.

Ethylene Oxide / Ethylene Glycol production

Accurately measure the molecular balances of carbon and oxygen to validate accuracy. Preferred technology for catalyst development research, where the goal is to increase the efficiency of the catalyst at high rates of activity.

Polyolefin production

Clearly track the variation in the hydrogen/ethylene ratio with greater precision than other gas analyzers.

Ammonia production

High accuracy for feed gas composition and calculated heating value; reduces energy consumption due to the tight control of the steam-to-carbon ratio (±0.01%).

Fugitive emissions of toxic VOCs

Monitor 100 or more sample points, within 15 minutes, with species-specific detection in the 0.01 to 1 ppm range.

Flare gas monitoring

Comply with regulations 40 CFR Parts 60 & 63 and 40 CFR part 60 (subpart ja). Report net heating value and sulfur.

In May 2020 EPA finalized amendments to the 2003 Miscellaneous Organic Chemical Manufacturing National Emission Standards for Hazardous Air Pollutants (NESHAP), known as MON. This adds monitoring and operational requirements for flares that control ethylene oxide emissions and flares used to control emissions from processes that produce olefins and polyolefins. It also allows facilities outside of this subset to opt into these flare requirements in lieu of complying with the current flare standards.
