Process Gas Conceptual Needs – Better Control, Less Use Waste Gas Natural Gas and Liquid Fuels Process Gases and Liquids (Vapors) Fixed Flow or Single Gas High Use (H) Std. Multi-Gas Adds Control Med. Use (M) Complete Gas Control/Reuse Low Use (L) Amounts H M L Gas. Based Process Reactor 5

Typical Process Gas Control Measures Only One Gas Species ® Example Types ® Zirconia Oxygen Probe – Measures Oxygen ® Dew Point Meters – Measures Water Vapor ® Electrochemical Cells – Low Range Single Gases ® Thin Film Technologies – Too Many Interferences ® Benefits ® Proven Technology (Typically) ® Lower Capital Cost ® Low Complexity ® Disadvantages ® Other Gas Constituents Assumed (Guessed) ® Assumptions Often Wrong ® Least Accurate Process Control Option ® Limits Process Control Options & Improvements 6

Improved Process Gas Control – Absorption-Based Optical (IR) ® Measures Multiple Gas Species ® Carbon Monoxide ® Carbon Dioxide ® Methane ® Benefits ® Proven Technology and Vendors ® Can be Used to Reduce Process Gas Use Somewhat ® Disadvantages ® Cannot Measure Most Diatomics (H 2, N 2, F 2, O 2, Etc. ) ® Expensive to Measure Many Corrosive Gases ® Detectors Have Limited Measurement Range ® Requires Frequent Calibration ® Species Measurement Has Significant Overlap ® Limits Use of Higher Efficiency Gas Mixtures 7

Other Gas Analysis Technologies – Higher Cost of Ownership ® Gas Chromatography (GC) ® High Installed Capital Cost ($25, 000 - $60, 000+) ® Slow (2 Minutes+) ® Complex – Use Requires Training ® Carrier Gas and Frequent Calibration ® Laboratory and Petrochemical Processes Predominate ® Mass Spectroscopy (MS) ® Higher Capital Cost ($50, 000 - $120, 000) ® Requires Vacuum Pump ® Ionizer Susceptible to Water Damage ® Expensive to Maintain ® Gas Mixtures Often Require Second Analysis Method 8
