Advantages of Monitoring Industrial Gases using Online FTIR Spectroscopy
Advantages of Monitoring Industrial Gases using Online FTIR Spectroscopy

FTIR spectroscopy offers several advantages for monitoring gases produced in industrial production, including combustion emissions and gases from production processes. The advantages are the ability to measure multiple gases simultaneously, rapidly, and continuously. This webinar explains practical considerations for use of FTIR for online monitoring as well as common errors and pitfalls that must be avoided for accurate results.

Topics include:

  • Overview of FTIR for gas analysis
  • Comparison of FTIR with other techniques
  • Sample handling considerations
  • Automated continuous operation

Rapid Combustion Analysis using FTIR Spectroscopy
Rapid Combustion Analysis using FTIR Spectroscopy

FTIR spectroscopy is a robust analytical method that can monitor multiple compounds in exhaust gases online with low detection limits and rapid response. This webinar reviews the challenges industrial chemists and engineers experience in assessing gaseous products of combustion found in:

  • Engines and catalytic converter design: Ability to measure 5 samples/second when reducing NOx emissions in the Selective Catalytic Reduction (SCR) cycle using ammonia or urea (NH3)
  • Powerplants and cement factories: Need to analyze HCl and SO2 emissions to meet stringent regulatory standards
  • Materials fire-safety testing: Need to rapidly identify toxic breakdown products (such as HCl, HF, HBr, or CH2O) for safety considerations

FTIR for Gas-phase Synfuels and Biogas Applications

FTIR spectroscopy may be useful for engineers and scientists involved in renewable energy research, such as anaerobic digestion of landfill or agricultural products to evolve methane for generation of electricity. FTIR can be used to monitor major components (CH4, CO, CO2), contaminants (siloxanes, acids such as HCl), and combustion products (NO, NO2, N2O). This webinar provides an introduction to FTIR for biogas analysis, including sampling considerations and factors in quantitative analysis.

Fire Science Gas Analysis by FTIR
Fire Science Gas Analysis by FTIR

Scientists in the field of fire safety or fire protection engineering analyze the combustion gases evolved when a material burns under different conditions. Fourier Transform Infrared (FTIR) spectroscopy provides fire safety engineers a useful analytic tool for online analysis of as many as 25 gas species of interest, including highly toxic acids such as HF, HCl, or HCN. Depending on the system configuration, detection limits of low parts-per-million (ppm) may be sampled to monitor evolved gases continuously.

Air Bag
The Air Bag method analyzes the effluent emitted during the air bag inflation. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.

Aviator’s Breathing Oxygen
The Aviator’s Breathing Oxygen (ABO) method is designed to detect impurities in ABO gas according to the US Air Force military standard 1564A. This method is used with the 10-meter gas cell. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.

Compressed Breathing Air
The Compressed Breathing Air (CBA) method analyzes CBA for impurities. This method is used with the 10-meter gas cell. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.

Exhaust Gasoline
Raw Exhaust method is designed for spark-ignition engine combustion analysis where gasoline is the fuel. The raw exhaust method covers concentration ranges found in the exhaust gas without dilution. The combustion gas sample is taken either before or after the catalytic converter. This method is configured with the Thermo Scientific™ 2-meter gas cell and a liquid-nitrogen cooled MCT-A detector. Detection limits are based on a 3-second sample time.

Diesel: Diesel exhaust differs from spark-ignition engine exhaust due to excess of air, leading to difficult-to-meet NOx reduction targets. FTIR is an excellent technique to study Selective Catalytic Reduction (SCR) compounds, including NO, NO2, N2O, and NH3.

Fire Science
The Fire Science method is configured to analyze toxic gases in the combustion of building materials. The method can be used with cone calorimeters, smoke boxes, or ambient sampling of combustion experiments. A corrosive-duty stainless-steel gas cell, such as the 2- or 10-meter gas cell, is recommended for this analysis. The 2-meter cell is recommended in all applications where the sample concentration is greater than 2 ppm; the 10-meter cell is recommended when analyzing samples below 2 ppm. Detection limits are based on a 3-second sample time with a liquid-nitrogen cooled MCT-A detector.

Renewable Energy
FTIR is an excellent technique for analyzing gases generated by new renewable energy developments, such as pyrolysis of wood chips or anaerobic digestion of garbage or manure. Synfuels and biogases produce environmental emissions, methane, along with other potentially harmful gases, for power generation. They also cause harmful effects on the combustion chambers or compressors. FTIR spectroscopy offers powerful capabilities to analyze synfuel and biogas components, enabling researchers to optimize their gas generation and collection techniques.

Specialty Gases
Gas applications that require high accuracy and stable calibrations take advantage of FTIR strengths. Used by specialty gas manufacturers, semiconductor purity testing, and identification of contaminants in O2 or breathing air.
