1 Dual Function Gas Analyzer For Industrial Monitoring Requirements Bill Pearman Ph.D Senior Scientist October 16, 2014 IPEC

2 Discussion Points Quick background on IMACC and FTIR Needs based assessment Brief (very) spectroscopic background Information Fourier Transform Infra-Red Raman Instrumental design and data comparison Planned events 2

3 Many Applications for FTIR Fence-line Monitoring Programs (Consent Decrees, new California rules, monitoring) Ambient Air Monitoring Stations (part of CDs, replacements) Stack testing firms (technology improvement) Flare Testing (passive, TCEQ and EPA accepted technique!) Flare Composition (alternative to $ GC technology) Fixed FTIR for process control (special applications) Research studies at Universities (volcanology, emissions monitoring, etc.) IMACC is seeking new technologies and advancing the application of proven technologies. 3

4 IMACC Overview Approved Technologies EPA accepted Technology Extractive FTIR testing Open Path FTIR 4

5 So what is the need? Continuous flare monitoring (BTU/scf of inlet vent gas. Calorific value predicts CE) Continuous flare control dynamic control of supplemental natural gas (add or remove, when, why) Dynamic control of steam/air assist (override potential) Emissions calculation speciation needed for reporting 5

6 Shortcomings with the Current solutions 3 flowmeters and 1 analyzer Flowmeter of choice uses ultrasonic technology no probe in large diameter pipe, but can t hear homonuclear diatomics Gas Chromatograph costly shelter, complicated sampling, calibration drift, calibration gases, limited analytes, response time lag 6

7 Industrial Flares Need (minute averaged results) A compositional analysis in near real time to provide - nitrogen and hydrogen results for compensation of ultrasonic flowmeters, Calorific value - BTU/scf MW calculation as qa/qc check of ultrasonics flowmeters Wider and fuller speciation of the vent gas Can we apply our strengths to develop a potential solution?? 7

8 Infrared Radiation William Herschel ( ): a renowned astronomer who discovered the planet Uranus in 1781; also discovered infrared light. The absorption of IR radiation transfers energy and heats the surface. IR radiation can be felt, but not seen by the human eye. 8

9 Requirements for IR Absorption To absorb IR radiation, a molecule must have a net change in dipole moment as a result of vibrational or rotational motion. For example, is a linear molecule. The electron density is distorted toward chlorine (electronegativity of 3.0) in comparison to hydrogen (electronegativity of 2.1). Molecules have dipole moments and are termed polar if their centers of positive and negative charge do not coincide. 9
